Ashe's Vicious Bandage

A creature of your choice that you can see within range regains hit points equal to 1d6 + your spellcasting ability modifier. Additionally, a spectral band wraps around the target where it was most recently injured. This band does not restrict that target's movement in anyway. While the band persists, if the target is hit by a melee attack, the band bursts into a shower of needles that deal 1d6 + your spellcasting ability modifier piercing damage to the attacker. The spectal band lasts for 10 minutes or until it is burst. This spell has no effect on undead or constructs.

At Higher Levels. When you cast this spell using a spell slot of 3rd level or higher, the healing and damage is increases by 1d6 for each slot level above 2nd.
