As a full-round action, you can spit poison up to 10 feet as a ranged touch attack. If you hit, the target must make a successful Fortitude save or be blinded for 1d6 rounds. The DC of this save is equal to 10 + 1/2 your total Hit Dice + your Constitution modifier. You can use this ability once per day plus one additional time per day for every three Hit Dice you have.
