Until the end of your next turn, the first time you hit with an attack during this spell’s duration, the target suffers the attack’s normal effects, and takes damage equal to your spellcasting ability modifier.  The type of damage dealt by this spell is the same as the type of damage you last took before casting this spell.  If you took more than one type of damage within the round before casting this spell, you choose what type of damage this spell deals from those types.  If you have taken 0 damage since the beginning of this combat, this spell ends with no effect.  

This spell’s damage increases when you reach higher levels. At 5th level, the damage to the target increases to 1d6 + your spellcasting ability modifier damage. Damage rolls increase by 1d6 at 11th level and 17th level.
