The Claws of Coleoptera are a secondary target in the battle with Coleoptera itself.
Coleoptera's claws automatically attack the player, but are immobile and cannot hit the player unless they are close. They can also strike the player when approaching Coleoptera's ribcage. The player must use ranged attacks to hit the claws, such as alchemy, a charged spear, or the Bazooka.
The Claws each reward a substantial amount of experience and Talons. If the player wishes to optimize rewards, they can take the time to kill the Claws, but it is easier to just focus on the heart.
