Chain Detonation

Choose up to five volatile marks, objects, hazards, traps, fragile objects, or creatures damaged by your volatile powers within range. Each detonates or ruptures. Creatures within 10 ft. of each chosen target must make a DEX save, taking 7d8 fire, acid, thunder, or force damage on a failed save, or half on a success. A creature can be damaged only once by this use.

This power has its own stable page so it can be linked from any character, item, location, story post, bargain, curse, or future reward.
