Bone Rush

You summon a bone the size of a shortsword, using it as a melee weapon. As an action, you can make a melee spell attack with your bone. On a hit, roll 1d4. The result is the number of times you hit the enemy, and the damage die for each hit is 1d6 force damage. For the duration of the spell you may dismiss or re-summon the bone(s) to your hand(s) as a bonus action.

At Higher Levels. When you cast this spell using a spell slot of 5th level or higher, you instead summon two bones, causing what you roll on the d4 to double upon roll.
