A gout of caustic bile streams from your mouth. You can choose to create a toxic circle around yourself or send a stream of bile at one creature.   Circle. You turn in a quick circle as you cast this spell, covering the ground in a 15-foot radius centered on you in slippery, acidic bile for 1 minute. The area becomes difficult terrain, and each creature, other than you, that enters the spell’s area for the first time on a turn or starts its turn there must succeed on a Constitution saving throw or become poisoned while it remains within the spell’s area.   Targeted. You spray a jet of caustic bile at a creature you can see within 30 feet of you. Make a ranged spell attack against the target. On a hit, the target takes 4d6 acid damage and is poisoned until it, or another creature within reach of it, uses an action to wipe off the bile.
