Bone Offering
Impale a Skeleton on a bone spike to shield your Minions while the spike remains, reducing the amount of damage taken from Hits. Taking a Hit that deals damage above a certain threshold will cause that Minion's shield to absorb all damage from that Hit, then explode. The bone spike is itself a Minion, and shields itself. If it dies, shields on your other Minions disappear.
