Soulfire crucible

Soulfire crucibles are nightmarish chalices which can gather death energy and expel it outward violently. Being lit and placed will cause a crucible to flare after the next fifteen deaths, dealing heavy fire damage to all adventurers in its location. The artefact cup is immobile once placed but will vanish after the allotted deaths, or after its owner dies, ending the cascade of pain in the room.
