Eight shrines

1    Ashwold

South of Tinslay is a tall square building of uneven rocks, veiled by spider web that extends in long white tresses to the surrounding trees and over the ground. A withered statue of great age rise out of the web; its pedestal bears the arrow-like mark of the Consolers and a nigh-unintelligible inscription reading DICIO * SATOR. Inside lives a great spider, tending to six large egg sacs of dense web that slowly moves. Denser patches of spider web on the grond cover six pit traps; if a character walks on them, they fall into the pit and lose their remaining movement. When they emerge, 1d4 young spiders follow.
GREAT SPIDER: Large (1d8), HD 4+2, AR 2, MV 6, dmg 1d6 + poison.
+ Climb: Each 1d8 turns, the spider leaps up in the ceiling, tree, or web; there it remains until it suffers damage, spraying a noxious acid at its turn (dmg 1d6, ranged, 3" area, everyone hit must save or armour is dented).
+ Poison: if at least 1 point of damage goes through armour, the target must save or suffer 1d4 damage/round until successfully treated
+ Erratic movement: if attacked and missed, the spider immediately moves 1d6" in a random direction.

YOUNG SPIDER: Small (-1d8), HD 1, MV 9, dmg 1d6 + poison.
+ Poison: if at least 1 point of damage goes through armour, the target must save or suffer 1d4 damage/round until successfully treated
+ Spider sense: the spider can evade any number of attacks and makes evade rolls at +6.

Egg sacs

1:    Corpse of a man, wearing a deep red robe. When opened, 1d4 young spiders crawl out from the sac each round until it is completely destroyed. The dead man has almost no nose and appears to have been an itinerant merchant of some sort, for with him is a wide array of pouches and goods. Most is now useless, but two firebombs, 1d10 pieces of glimmering red gold, and a parchment scroll. The parchment is badly damaged, but if carefully restored it contains a clue.
2-5:     wild animal, barely alive and crawling with spiderlings - when opened, all adjacent characters must evade or suffer a -3 penalty to all actions for the next round as their skin crawls with countless spiderlings. The dying animal has 1 HP and will move 1d4" in a random direction each round until dead. As long as it is alive, all adjacent characters suffer the -3 penalty.
6:    ragged man, alive but severely disfigured by the spiderlings feeding from him - when opened, all characters within line of sight must roll INT or be SHAKEN. The man is disoriented from the spider's poison but if saved, he turns out to be a local farmer who briefly travelled with Raillarde the Paynim as a guide. After a bandit ambush - which he had nothing to do with, he swears - he fled and never saw the knight again. Last he know, the knight was headed north, towards Belmyre.

2    Loudreác

Nine nine miles east of King's road is a small stone shrine, adorned with imagery of queen Aelwydd and surrounded by a low wall that is dwarfed by thistles and shrubbery. The wall is partly destroyed by the encroaching forest, but curiously has no visible gate. A statue of a old woman lies toppled among the weeds, its head missing. The inscription reads: GENTRX * CELSUS * NOSTER.
Inside sits a knight, motionless and reclining against the wall. If approached, the knight comes to life.
GODRYDD THE ACCURSED: HD 5, AR 6, Shield (1d8), MV 6, dmg 1d8+1d6 (longsword)

3    Langonne

An old chapel, slowly keeling into a dark pond. The chapel is adorned by the the tear-shaped mark of the Consolers, but the scarred oak trees surrounding the pond speak of ceremonies still older. If there ever was a statue or idol, it is long since lost. Inside the dark chapel lies a mummified arm in a monstrance, black like tar and smelling of rancid apples.
HAUNT: HD 2, AR 0, MV 5, dmg 1d8 magic
+ Deathless: The haunt is immune to all physical damage, but is immediately vanquished if its relic is destroyed.

4    Orvault

On a small island in a reed-covered lake are the ruins of a shrine, dwarfed by a cairn that better withstood the test of time.  The island is home to a band of goblins, whose cooing calls can be heard across the lake. Using sleds and snow-shoes of twigs, the light goblins can move through the dense reeds without getting wet; for everyone else, the reeds counts as difficult terrain. A great lamprey lives in the lake, feeding of animals that get stuck in the mud, and the goblins are careful to move quickly across the reeds and stay away from any open water.
GOBLINS (3d6): small (-1d8), HD 1, AR 2, mv 6, dmg 1d6 (bows: ranged, poison arrows - save or DOWNED) or 1d6 (spears).
+ Pack tactics: Ignores size penalty if outnumbering target

GIANT LAMPREY: HD 4, AR 0, MV 8/4 in reeds, dmg 1d4 + grapple
+ Motion sense: The lamprey relies on motion to find its prey; each round not in melee, it prioritizes moving towards the largest splash or disturbance of the water surface, then the nearest, or else moves at random. It will only attack characters or creatures that are in the water.
+ Grapple: A target successfully grappled by the lamprey is pulled under water, where they suffer 1d4 fatigue per round from asphyxiation.
+ Submerged: The lamprey only rises from the water to attack, otherwise its position is only revealed by the parting reeds. When submerged, the lamprey is in full cover to all but adjacent characters.

5    Egwyn Fach

A sturdy shrine built from neatly-fitted and perfectly square stones sits untouched by time among elderflower trees and rows of salsnip. A pathway lead across the garden to the shrine, each of its of white stones carrying a brown mark looking like a cloven hoof. Inside the floor is covered by hay and fragrant branches. Here lives a peaceful hermit Eroästes and his sheep, collecting wild flowers to adorn a large statue of the God Mother. The hermit speaks only sparingly, but is otherwise happy to help. He knows medicine and has a few books; if studied, one of them provides a clue.

6    Soudan

A walled-up cave by a small stream forms an inconspicuous shrine, built at the foot of a long path leading up a steep hill. A nearby stone reads FARAN - AELWYDD THEODCWEN - BYLDED - CIRCE. Inside the shrine is a travelling merchant.

7    Derrill

By a swampy pond leaking into the Wallingwall channel is a wormstung timber shrine. Inside, the floor stones form the tear-shaped mark of the Consolers. The nun Odille is resting inside; fleeing from Whitesun she is terrified of man-masked demons, but is friendly if convinced that the PCs are mortals.

 8    Pyworth.

A turret-like shrine, walled by several low rows of standing stones. Outside the perimeter of the stones is an encampment, flying the flag of Tuillote of Haute-Occ. His retinue is currently tending to the badly wounded knight and several graves give testimony to recent casualties.

Inside the shrine, stone stairs leads down into a vast, dark chamber where the Foot of the Bleeder is kept. Here resides Lantern Knight Gwent, the formidable foe who has so ravaged the noble knight outside.
TUILLOTE (wounded): HD 2 (fights as HD 5), AR 6, Shield (1d10), MV 6, dmg 1d14 + 1d4 magic (spear called Segwryck) or 1d8 (sword).
RETINUE (2d4): HD 2, AR 4, Shield (1d6), MV 6, dmg 1d10 (axes)

1d6 graves of fallen knights

1.

A large rock, overgrown with ferns. Crushed underneath are the remains of a nameless Knight. The troll that hurled the rock still lairs nearby; ancient and wicked she carries the skull of the dead knight on her club, occasionally swearing at it or ridiculing it.
HAG-TROLL: Huge (2d8), HD 6, AR 3, dmg 1d12 (gt club: knockback, area) or 1d12 (boulder: ranged, 2x2 square area)

+ Mesmerizing song: Each 1d8 turns, save or be paralysed.
+ Regenerates 1HD per round. Immune to magic.

2.

The pine-forest here is quiet, and bones litter the ground. Among the lichen-covered trees lie a heap of toppled stones - all that remain of the once-splendid grave of Byrla the Shield. Each night the dead knight returns to cursed life, intent only on killing. If vanquished, the knight begins hauting again at the next full moon unless the body is placed in hallow soil.
CURSED KNIGHT: HD 5, AR 4, Shield 1d16 (3), dmg 1d8 + 1d6 magic (cursed sword).

+ Unhallowed charge: Each 1d4 rounds, the knight charges 2d4 squares forward and attacks with an impaling strike: target must save or suffer 1d12 magical damage and lose 1d4 Spirit.
+ Fay Shield: The Fay Shield of Byrla protects against all types of damage, and reflects the damage back at the attacker if the shield roll is higher than the damage roll. If taken from Byrla, it breaks and withers on a roll of 1.
+ Cursed: Cannot cross running water, must return to corpse at daybreak.

3.

A solemn stone of pink granite marks the grave of Brathos of Werelden. The inscriptions read "As in life, so in death." A large family of wild boars have partly exhumed the bones through extensive burrowing; curse-stricken, they now hunt for food. The boars secrete a dark oil that turn their manes into porcupine-like quills, and gradually kills the forest surrounding their lair. On the week of a full moon, there is a 1-in-4 chance that Gloso is among them.
QUILLED BOAR (3d4): HD 2, AR 2, MV 9, dmg 2d6
Charge, knock down, disengage

+ Bristles: when evading an attack, the boar deals 1d6 damage to the attacker
+ Death struggle: when reaching 0 hp, the boar immediately makes a melee attack before dropping dead.

GLOSO: Large (1d8), HD 6, AR 4, MV 9, dmg 2d8
Charge, knock down, disengage

+ Poisonous exhale: Each 1d4 rounds, Gloso exhales a cloud of black smoke covering 1d8x1d8 squares. The cloud obscures line-of-sight and dissipates at a rate of 1 square in each direction per round. Everyone in the cloud must save or suffer 1d6 poison damage (no armour).
+ Bristles: when evading an attack, Gloso deals 1d6 damage to the attacker
+ Death struggle: Each 2 HD lost, Gloso immediately makes a melee attack.

4.

A great heap of branches and fallen trees adorned with feathers mark the nest of a huge bear-like creature. Beaked and feathered like an owl, it hunts mainly at night and is at disadvantage in direct sunlight. Tangled in the roots in one of the storm-felled trees are broken human bones, barely held together by fragments of green fabric with gold-tread inlay. This is the remains of a nameless knight. If investigated, a sword can be retrieved from the light-brown soil (as longsword; crit on a 19-20).
OWLBEAST: Large (1d8) HD 4, AR 4, MV 6, dmg 1d8 + knockback (area) or 2d6 + grapple

+ Pounce: Each 1d8 turns, the Owlbeast leaps forward 2d4 squares. All PCs in its path must evade or be pushed forward and suffer 1d6 damage (half protection from armour) as they are crushed under the terrible weight of the landing beast. In addition, the Owlbeast may make a single melee attack with its beak upon landing, dealing 2d6 damage (rending: armour reduced by 1).

5.

In the flooded ruins of a small stone temple lives a tribe of leech-skinned goblins. Inside the temple is the remains of Sir Folming; mummified in the marsh, the goblins have exhumed the body and distorted it into an grim idol.
LEECH-GOBLINS (3d6): Small (-1d8), HD 1, AR 4, mv 6, dmg 1d6 (spear).

+ Pack tactics: Ignores size penalty if outnumbering target
+ Impossible to shake: The goblins gain a +3 bonus to grappling; when the grappling goblin is removed, the grappled character suffers 1d3 damage for each failed attempt to break free from it.

GOBLIN LEADER: Small (-1d8), HD 4, AR 4, Shield 1d4(2), mv 6
dmg 1d8 +1d4 magical (sword)

+ Command: Each 1d8 turns, the leader issues an order and the other goblins must immediately charge towards a target or hurl their spears at a specific target. All goblins must follow the same order, towards the same target.
+ Spear of Folming: the leader uses the head of the mummified knight's spear as a sword. If repaired into a spear, its damage increases to 1d10 + 1d6 magical but any failed attempt will dent the weapon.

6.

The wind carries the sweet fragrance from a glade where butterflies swarm over ever-flowering thorns. In the middle of the glade lies the remains of sir Heaved, peacefully as if resting. If the body is removed, the glade will slowly die but similar flowering thorn-bushes will sprout forth over the course of 1d6 days from all dead matter the body touches until it is placed in hallowed soil.

Sample potions

The feasibility of the sub-system for Alchemy I proposed for the alchemy month hinges on the presence of multiple formulas for the same potion. Only by finding two or more formulas that creates similar effects will players have a chance to understand the principles of correspondence and substitution. The presence of multiple formulas also reinforces the notion that formulas are more like recipes for cooking than chemical notation; or that they consist of equal measures fluff and crunch.



To better show what I mean, I've made a small pdf containing three variations on a potion of restoration, and three variations on a potion of healing. While they are designed with this system in mind, you can also use them as stand-alone handouts if you just want to award your players with a tangible representation of their scroll or similar.

Rules for Alchemy

Apparently, there is an alchemy month going on. That's neat, since I've been thinking a lot about alchemy now that my campaign is on pause. Here are my rules. They are not at all playtested, but at least in theory I'm really happy with them.

The basic idea is that alchemy should be about formulas, trial and error. The system therefore makes a strong distinction between simple player-facing rules which are basically "say a prayer, and follow the formula" and more involved referee-facing rules which governs how formulas should be designed. For most players, alchemy is consequently about finding a formula and questing to retrieve the ingredients. For those who want, however, alchemy instead is about trying to understand what makes the potion effective, and/or trying to improve it.

Hopefully, you can find some ideas worth stealing. An example formula can be found here; and there is plenty of inspiration for more over at Slugs and Silver.

A system for Alchemy

PLAYER-FACING RULES

Alchemy is a craft based on a secret system of mystical correspondence. To create an alchemical potion, your character needs
- A formula
- The required ingredients
- Paraphernalia and tools

Any character possessing these things can be an alchemist. To become a master requires understanding the correspondences that govern all of creation - a task that may easily consume a lifetime.

Preparing a potion

Before preparing a potion, alchemists commonly fast, say a prayer or invocation that will compensate for their impending blasphemy. Failure to take proper precautions results in minor corruption (-1 Spirit).

After these precautions, just follow the formula.

Determining the Effect of a Potion

The potion's effect is determined by three things
- The formula
- The alchemist's INT
- How closely the formula was followed

When the potion is used, or otherwise tested, roll d20 and add INT of the character preparing the potion to determine its quality.
Formula was followed exactly
- the potion always has effect
- failed INT-roll means side effect: minor corruption (-1 Spirit)
- natural 1 means side effect: major corruption (-1d4 Spirit)
- natural 20 means potion not depleted; it was so effective it can be used again

Minor deviation from the formula- the potion only has effect on successful INT-roll

Major deviation means the potion never has effect.

Creating new formulas

If a process involving minor deviations is successful, it can be codified into a new formula. Once codified, it is no longer considered a minor deviation for rules purposes. To codify the process, the player simply writes it down.

Prepared potions

A prepared alchemical potion should be noted as
"Potion of healing (minor, +3)"
indicating the formula used, how closely the formula was followed, and the INT of the alchemist.


 REFEREE FACING RULES BELOW





REFEREE FACING RULES

For referees only, below image.

The Formulas

There are three basic types of alchemical formula:
- Pure
- Diluted
- True
When designing formulas, you start with the Pure.

The Alchemical Principles

To design the formula, you first decide what class of potion it will result in.

There are four alchemical Principles, or classes of potions, corresponding to a colour each. All potions use a base that is determined by their principle. They are
- White (purify, heal): White wine, distilled alcohol, fermented milk, or other white/clear liquid intoxicant
- Yellow (enhance): Ale, Mead, or other yellow/golden liquid intoxicant
- Red (alter): Red wine, or other red liquid intoxicant
- Black (?): Ichor

A healing potion will thus be white, a potion of giant strength yellow, and a potion of growth red. The black are there as a possibility; not currently part of my campaign.

The Pure formula

The Pure formula consists of 5 components
1 base- An intoxicating liquid of a colour determined by the Principle of the potion.

3 ingredients
- A natural ingredient (something from nature)
- An unnatural ingredient (something made)
- A preternatural ingredient (something with magical or mystical properties)

1 reagent- Salt or potash gives a normal potion
- Sulphur gives a weak potion (+3 to INT roll)
- Mercury gives a strong potion (-3 to INT roll)

Diluted formulas

Over time, many formulas become diluted when passed from Alchemist to Alchemist, or developed from flawed understanding of the pure process. A diluted formula has the same effect as a Pure formula, but contains more than the 5 required ingredients. These additional ingredients may give side effects, but are commonly just cosmetic. For example: an alchemist may decide to add honey to a potion where honey is not required, just because they prefer the taste or to see if a rival alchemist is stealing their formula (and thus also including the unnecessary honey).

Using a diluted formula means characters have to collect more ingredients, but otherwise carries no penalties.

True formulas

Through clever substitution (see below), it may theoretically be possible to create a formula with less than 5 components. The hypothetical formula using the least number of components to create an effect are known among alchemists as True formulas.

Substitution

Alchemy works through correspondence. Thus, all components can be substituted with another component of sufficent similarity. For example, red wine may be substituted as a base by blood and white wine, and a hippogrif egg might perhaps be substituted by the egg of an eagle raised among horses. Substitutions like these are considered a minor deviation.

If a substitution is successful (meaning: the character succeeds with the INT roll to determine the potion's effect), the character can codify the process as a new formula. In game, this is done by a player writing down the process. Through iterative attempts of substitution and codified processes, a clever alchemist might eventually arrive at a formula that is very different from the original.

3 Lantern Knights

Here are three lantern knights, supposed to the mini-bosses in my campaign. Like dragon-hauted Cabour the format is inspired by wisdom from a lot of other sources - such as "paragon creatures" - in hope of making solo monsters that can pose a challenge to a group of players. They are not playtested, so whether it works or not I do not know.

Four basic ideas:
- Each lantern knight has a single theme for its special attacks. This should make it possible to anticipate actions, even when the knight is only encountered over a few rounds of combat.
- The special attacks are mainly tied to turn timers. This forewarns of their coming in an obvious way, but also interrupts the back-and-forth of sidewise initiative.
- Special attacks are also set up so that one timer (d8) is tied to ranged and the other (d12) to melee. This should make it possible to interrupt the attacks through positioning, thereby encouraging movement.
- Each lantern knight has more than one HD pool that must be depleted in order. When one is reduced to zero, the circumstances of the encounter changes substantially.

I hope they survive playtest, because the format seems manageable both to write and to run.

ALASTER
Proud and oblivious of his fall, his shielded lantern glows like a sun.

HD 7/7
- Exquisite armour (ar 8, magic 4, flame 4)
- Blackened crossbow (dmg 1d12/magic, range 12)
- Champion sword (dmg 1d12/magic, fast, deathblow)

Radiant: all characters starting their round within 2 squares of Alaster must suffers 1d4 damage (no armour).

Unnatural life: Alaster has two HD pools. When one pool is reduced to zero Alaster is downed. Any surplus damage is lost, and all ongoing effects targeting him ends.

Demonic actions: Alaster has 1 bonus round (move AND attack) per HD pool.

Unshielded radiance (downed): When a HD pool is reduced to 0, the metal cover than shields Alaster's light is is dislodged. When this happens, the damage of radiant and consuming light doubles (to 2d4 and 2d8, respectively).

Turn timers
1d8: Mothlight. If not in melee, Alaster lifts his lantern and lets it burn like a beacon. All characters within line of sight must save or make a full movement directly towards him. In addition, all actions are HARD for affected characters until next turn.
1d12: Consuming light. If in melee, Alaster covers his face with his arm and lets the lantern burn unshielded. All characters within 2 squares must save or suffer 1d8 damage (no armour) as their flesh boils under the horrible light.


BLAINE
A hulking mass of armour and weapons, carrying a faint candle like a captured bird.

HD 5/5/5, Large (+1)
- Layered armour (ar 8/4/2, magic 6), evade +0/+2/+4
- Jagged greataxe (dmg 1d14, reach 1, deathblow, rend: save vs total damage or armour is dented; dent it again and AR is irreparably reduced by one).
- Blunt greatsword (dmg 1d12-1, reach 1, deathblow, knockdown).
- Hand axes (dmg 1d10 each, rend: save vs total tamage or armour is dented).
- Rusted short sword (dmg 1d8-1, fast) and fractured shield (ar 1d8-1)
- Improvised weapon (dmg 1d6-1, close, knockdown).

Unnatural life: Blaine has three HD pools. When one pool is reduced to zero Blaine is downed. Any surplus damage is lost, and all ongoing effects targeting him ends.

Demonic actions: Blaine gains 1 bonus round (move AND attack) per HD pool lost.

Shed (when downed): When a HD pool is reduced to 0, Blaine crawls out of his armour like an insect breaking free from its cocoon. Each time this happens, AR is halved (to 4, then 2), evade increases by +2.

Turn timers
1d8: Hurl weapon. If not in melee, Blaine moves up to full movement and throws his weapon at the most exposed target (as weapon, range 12, knockdown).
1d8: Special attack. If in melee, Blaine performs a special attack (per weapon).

Special attacks
- Destruction (axe): all characters in melee must save or suffer half damage and have their armour dented.
- Stunned (sword): target character must save or become stunned for 1d3 rounds and have their helmet torn off and thrown 1d6+5 squares in random direction.
- Tear (unarmed/other): Blaine grabs the target character and starts tearing: save or armour is ripped/deformed (AR -1).

GWENT THE GAUNT
A skeletal knight long since fallen from honor, sustained by the cold light of his lantern.

HD 4/4/4, Large (+1)
- Chain +1 (ar 5, flame 4)
- Thin spear (dmg 2d6, piercing 3, reach 2, deathblow)

Impaling strike: If any damage dice shows max damage, the spear is stuck in its target. Impaled characters cannot move without suffering 1d6 damage (no armour). Removing the spear is an action, requires a STR check and results in 1d6 damage (no armour).

Fling: Instead of dealing damage, the attack sends the target 2d4 squares away. If target is impaled, no attack roll is needed.

Unnatural life: Gwent has three HD pools. When one pool is reduced to zero Gwent is downed. Any surplus damage is lost, and all ongoing effects targeting him ends.

Demonic actions: Gwent has 1 bonus action (move OR attack) per HD pool.

Lights out (when downed): When a HD pool is reduced to 0, the lantern's light fades. As long as there are no other light sources all character-actions requiring sight are HARD, and Gwent strikes from behind and with surprise each turn, if possible. During this time, no turn timers are rolled. Gwent re-lights his lantern once there is another light source.

Turn timers
1d8: Blow fire. If not in melee, Gwent moves up to 3", lifts his lantern and blows fire (fire dmg 1d10, area 6:2, save or catch fire for 1d4 fire damage per round until put out).
1d12: Burn. If in melee, Gwent uses his lantern to burn the most susceptible opponent (fire dmg 1d4, save or catch fire for 1d4 fire damage per round until put out).

Dragon-haunted Cabour

A ruined city, shrouded in mist from the dragon's nauseating breath. You have come here to find a relic, lost when its bearer fled from the terrible dragon. Years have passed since the ancient creature last was seen, but you know it remains here. Biding time. Waiting.
It knows about you, too.

NOTE: This is meant as a boss encounter, so there are a lot of things going on. Inspirations come from Arnold K's bosses and  dynamic encounter, stages from Whitehack and discussions on the Runehammer forum.
Click for large


Setup
A chasm across the board, a hill, several towers and trees. Scatter ruins.

Six hidden entrances to the dragon's lair.

Structures are close enough that you could make a desperate leap from one to another, far enough that it requires a roll, and high enough that falling results in substantial but not fatal damage (2d6, no armour, dex roll for half). All floors are in poor condition, breaks on a 1-in-4 unless the character moves with caution.

The relic
The relic is located by some of the scatter ruins (decide beforehand). It beckons quietly. 

Searching for the relic
A PC can search for the relic as a normal action by rolling WIS. On a hit, the referee says if it is close, near, or far. Searching at the exact correct location instead results in 1d4 effort (1d6 if some device is used) - at 10 effort the relic is found.

The dragon entrances
There are six entrances to the dragon's lair. They start hidden, but an entrance is immediately revealed if a character is adjacent to it. A PC can enter through an entrance as a normal action. If so, they are removed from the board. Next round the player rolls WIS: on a success, they can chose to enter at any known or a random unknown (not yet revealed) entrance. On a miss, they are ambushed by the dragon (Phase 1) or lost for another round (Phase 2+3).

The encounter

The encounter is played in three phases, defined by the dragon's activity: lurking, hunting, flying.

Phase 1: Lurking. Room TN 10
Timer. 1d6 TURNS, TN increases by 1

Dragon is not placed, hides in its lair. Roll 1d6 to decide in which entrance.

- TN increases by +1 per round.
- TN increases by an additional +1 for all PC actions that are not very quiet (roll DEX if in doubt), or +1d4 for all loud actions
 
When TN reaches 20 the dragon attacks from ambush (fire breath). After that, it retreats to a random non-revealed entrance phase 1 restarts.
If the dragon is found, phase 2 begins.

Finding the dragon
A PC can search for the dragon as a normal action by rolling WIS. On a hit, the referee says if the dragon is close, near or far based on approximate distance to the entrance the dragon is in. If a PC moves close to an entrance it is automatically revealed. If the PCs find the entrance where the dragon is, phase 2 begins.

Phase 2: Hunting. Room TN 15
Timer. 1d6 TURNS. Dragon gets another turn.
Dragon is placed and goes hunting for the PCs.
It targets, in order of preference: 1) as many as possible, 2) a mortal threat if present, 3) fleeing, cowering, hiding characters, 4) anyone else.

Nowhere to hide. Destroy at least one piece of terrain per turn, as a side effect of the dragon's attacks (example: it crashes through a wall to catch someone hiding on the other side).

When the dragon is reduced to 0 HP, phase 3 begins.

Phase 3: Flying. Room TN 15
Timer. 1d6 TURNS. Dragon gets another turn.
Dragon is returned to full HP.
It leaps up in the air and starts flying. PCs standing under it must roll STR or be knocked down from the force of its wings.

When the dragon is reduced to 0HP again, it crashes down (dead?).

The Dragon of Cabour

HD 7, Giant: 3d8, MV 4 (increasing by one per round flying, max double)
Fire breath. Use a template. Automatically hits everyone within for 4d6 fire damage & -1 to a random stat unless they evade. Full cover reduces damage by half. On doubles/triples/quadruples, the fire keeps burning on the area covered by the template for 2/3/4 rounds.
Can only be used when attacking from ambush or if foreshadowed one round in advance (free action).

Bite (1d10) + Claws (1d8) + Tail (1d6, knockdown). All have reach 3. 

Special. If flying, a successful claw attack means the dragon carries the target off to throw it or drop it in a following round.
