Natron Eruption

HAZARD 7

Stealth +20 (expert)

Description Negative-energy charged natron sprays out of the tub and starts to mummify nearby creatures.

Disable DC 27 Thievery (trained) to safely remove the umbral vise from the tub without triggering the natron or Dispel Magic (4th rank; counteract DC 25) to counteract the ritual energy.

Mummify (divine)

Trigger A creature touches or disturbs the umbral vise.

Effect Natron sprays out of the tub, infusing all creatures adjacent to the tub with void energy and desiccating their internal organs. Each creature takes 2d10 void damage and 2d10 poison damage (DC 29 basic Fortitude save). On a failure, the internal damage makes the creature more susceptible to other effects that would cause it to mummify, such as Mummy Rot. For 1 day, the first time it is exposed to such an effect, it uses the outcome one degree of success worse than the result of its saving throw.

Reset The trap resets after 24 hours.
