Beetle Rush

Your arms and weapons become enwrapped in a bright beetle- like shell covered in spikes. When you make a melee weapon attack it does an additional 8 (3d4 + 2) bludgeoning damage plus 4 (1d4 + 2) piercing damage. Also, any unarmed strikes you make do an additional 8 (3d4 + 2) piercing damage.  

When using a spell slot of 2nd level or higher you do an additional 4 (1d4 + 2) bludgeoning damage per spell slot level for both melee weapon attacks and unarmed strikes.
