Bone Shield

You generate a barrier of elongated femurs that protects you. You reduce the incoming damage by 6, and if the attacking enemy is within 10ft of you, the osseous barrier explodes, dealing 6 slashing damage to them.
At Higher Levels. When you cast this spell using a spell slot of 2nd level or higher, both the damage reduction and the slashing damage increase by 6 for each slot level above 1st.
