Ritual Effects

COMPLEX HAZARD 5
Stealth +8
Description The effects of Hesla's profane ritual ripple outward through Deskari's Gullet. Physical tremors shake the cavern complex, while magical waves of energy affect those opposed to her actions.

Disable This hazard persists until Hesla's ritual is complete and her demonic forces defeated.


The Ritual Continues
Trigger Combat begins within Deskari's Gullet

Effect The Ritual Effects roll initiative. Each combat indicates how often this hazard triggers during that combat.
Tremors

Targets take 1d8+4 bludgeoning damage (DC 23 basic Reflex save) as rocks fall from the ceiling. On a critical failure, the target falls Prone.

Demonic Energy

Targets take 1d8+4 void damage (DC 23 basic Fortitude save). On a critical failure, the target is Sickened 1. Holy creatures treat their save as one degree worse for the purposes of the sickened condition only.

Routine (two actions) The ground shakes, and waves of demonic energy surge through the cavern. Each PC must make a save against tremors and a save against demonic energy. Enemy combatants must only make the Reflex save against tremors; they are immune to the Demonic Energy effects.
