Skill Amber: Burning Fang

Amber containing a skill Koo can learn. Burning Fang performs an attack that burns foes. Every Skill Amber description ends with the same sentence — "Koo uses this skill automatically" — which puts these on the same footing as the equipped Koo skills IGN describes as firing without an input.

When to use it

Burn pairs with the Infernal End stone, which makes burning enemies explode on death — the clearest published combination between a Koo skill and an Emma stone. All seven come from Wandering Merchants, so this is a category you buy rather than find, and only three of the seven have a published price.

Builds using this

No build on this site currently lists this piece of gear. It is documented here because a source describes it, not because a creator built around it.
