Tactics
Stay at the side of the map so the Bone Walls hit the enemies if they aren't paying attention.

Pairing Bone circle + Blue bone zone can be a good way to get damage off your opponents.

A viable option is to use your Bone shield to trap enemies and use Bone circle for guaranteed damage (this is not easy to pull off)
