Elemental Spit

You touch one willing creature and imbue it with the power to turn their spit into an elemental conduct, provided it has a mouth. Choose acid, cold, fire, lightning, or poison. Until the spell ends, the creature can use a bonus action to spit out a projectile of the chosen type up to 60 feet, roll a ranged attack that the creature is proficient in, doing 2d6 damage of the chosen type on hit

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