Camel Spit

You alter your stomach, esophagus, and tongue to be able to spit partially digested food with force. You can spit at a foe once you finish Casting the Spell and can repeat the attack once on each of your subsequent turns by taking a single action, which has the acid, attack, and concentrate traits. After your third spit attack, the spell ends. When you attack with camel spit, make a ranged spell attack roll against a creature within 15 feet, dealing 1d6 acid damage and causing the target to be for 1 round if you hit. On a critical hit, you deal double damage and the target takes ] damage.
