Cornterspell

You attempt to interrupt a creature in the process of casting a spell. The creature must make a Constitution saving throw or be forced to choke on an ear of corn for one minute. Choking in this way prevents somatic components of spells. Spells without somatic components ignore this detriment but the caster is still considered choked. A choked creature cannot speak and makes the constitution saving throw at the end of each of their turns. For each time they fail the save again, they take 3d6 bludgeoning damage
