Forgefire

Kindle supernatural forgefire in a handheld object, weapon, tool, forge, engine, or campfire. For the duration, the target burns without fuel, cannot be extinguished by mundane water, and can melt, weld, cook, purify, or temper materials as if using a fully equipped forge.

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