Draconic Jaws

You touch one willing creature and imbue it with the power of a dragons bite, provided it has a mouth. Choose acid, cold, fire, lightning, or poison. Until the spell ends, if the creature makes a bite attack against a target it also takes 1d8 damage of the chosen type.

At Higher Levels. When you cast this spell using a spell slot of 3rd level or higher, the damage increases by 1d8 for each slot level above 2nd.
