Shadow Heart

COMPLEX HAZARD 9

Stealth +20 (expert)

Description A heart of tumorous, shadowy tissue unleashes magic on nearby creatures.

Disable DC 26 Arcana or DC 26 Occultism (expert) to counter the heart's offensive magic, or DC 28 Religion (trained) to purify the area containing the heart. Four successes are required to disable it; after two successes, the shadow heart can't use its shadow lash Strike.

AC 28; Fort +21, Ref +15, Will +18

Hardness 15, HP 72 (BT 36); Immunities critical hits, precision; Weaknesses fire 10, vitality 10

Shadow Pulse

Trigger A creature approaches within 10 feet of the heart

Effect The heart gives a slow beat, and all creatures in the room must succeed at a DC 30 Will save or be Stunned 1 and unable to take reactions for 1 round (Stunned 3 on a critical failure). The dark heart then rolls initiative.

Battering Vortex

A swirling vortex of shadows forms around the heart, lifting all creatures in the room and slamming them forcefully to the ground, dealing 4d10 bludgeoning damage. Each creature must attempt a DC 30 Fortitude save. Anyone adjacent to a wall may Grab an Edge with a successful DC 28 Reflex save; on a success at Grabbing an Edge, the creature uses a result one step better than the roll of their Fortitude save.

Critical Success The creature is unaffected.

Success The creature takes half damage and is knocked Prone.

Failure The creature takes full damage, is knocked prone, and is Clumsy 1 for 1 round.

Critical Failure The creature takes full damage, is knocked prone, and is Clumsy 3 for 1 round.

Melee Shadow Lash +21 (cold, reach 30), Damage 3d4 cold

Routine The shadow heart uses Battering Vortex, and then uses shadow lash on a random creature within range.

Reset The heart deactivates if there are no creatures present in the room. It resets in 1 hour.
