Deeply Flawed Ritual

COMPLEX HAZARD 5
Stealth +0
Description A flawed ritual emits surges of shadowy energy and opens tiny breaches into the Shadow Plane.

Disable

Seven flaws have appeared in the ritual circle, dancing like shadowy flames. Each of Tavvar's three aides keeps one flaw under control as long as they are alive, while Tavvar herself staves off the ritual's implosion as listed in the ritual anchor ability below.

Each flaw can be repaired with a successful DC 24 Occultism check or DC 20 (trained) check using a skill related to the flaw's original cause (see the table below). Regardless of success or failure, a PC who attempts an Occultism check to disable the hazard learns the cause of the flaws and the skills that can be used to overcome it.

Each success on a check to repair a flaw using these other skills reduces the DC of the Occultism check to repair a flaw by 2. Instead of using skill checks, the PCs can use force to stabilize the ritual. A PC who defeats a shadow wisp automatically repairs one flaw.

d4Cause of FlawSkills to Overcome
1Harried (a "publish or perish" culture at the College of Mystery led to Tavvar cutting corners in the ritual's execution, so some runes aren't drawn quite right)DC 20 Arcana (trained) or DC 20 Thievery (trained)
2Misplaced Affection (Tavvar is from Nidal and subconsciously hopes the ritual will show that there is some good in her homeland; she included some Shadowtongue in the runes and it's enhancing the energyDC 20 Society (trained) or DC 20 Religion (trained)
3Cloistered (Tavvar hasn't done much field work and made a dangerous mistake in which mushrooms she used in the ink for the runes)DC 20 Crafting (trained) or DC 20 Nature (trained)
4Restrained (Tavvar's own hesitation and self-doubt has led to the ritual slipping out of her control)DC 20 Deception (trained) or DC 20 Diplomacy (trained)


Ritual Anchor

If Tavvar dies, the ritual immediately ends disastrously. With a loud pop, it explodes, inflicting an additional surge of shadowy energy on every creature in area B5 before dissipating. This ends the ritual but does not remove any shadows that are already in the room.

Routine

(1 action) On each of its turns, the ritual lets out a surge of shadowy energy, dealing 4d6 void damage (DC 22 basic Fortitude save) to each character who participated in ritual the past round (including Tavvar and her aides as well as any PC who attempted a skill check to disable the hazard). A non-participant can step in front of a participant as a reaction. This blocks the damage from the ritual caster, but the non-participant must then attempt the Fortitude save.

In addition to dealing damage, the ritual's surge of energy brings a Greater Shadow Wisp into the room. Wisps act at the end of the ritual's turn. If there are already two shadow wisps in the room, instead of creating a new wisp, the ritual restores 10 healing Hit Points to each wisp.
