Fuse (Unstable Foundations) detail
Unstable Foundations pillar

A pillar with a fuse attached.

A fuse was a component in an explosive device used by Sir Vant and the player to kill a dragon. It was attached to a pillar then lit, causing the Unstable Foundations to collapse.

Despite having a drop option, it is actually destroyed if dropped.
