Starting at 1st level, you can make a melee touch attack as a standard action that inflicts 1d6 points of nonlethal damage + 1 for every two sorcerer levels you possess and sickens the target for 1 round. Oozes, plants, and creatures with the aquatic or water subtypes suffer lethal damage instead. You can use this ability a number of times per day equal to 3 + your Charisma modifier.
