An octopus can emit a 10-foot-radius sphere of ink once per minute as a free action. The ink provides total concealment in water, and persists for 1 minute.
An octopus can jet backward once per round as a full-round action, at a speed of 200 feet. It must move in a straight line while jetting, and does not provoke attacks of opportunity when it does so.
Bite—injury; save Fort DC 13 ; frequency 1/round for 6 rounds; effect 1 Str; cure 1 save.
Once per day as a swift action this creature can add their Cha modifier to their attack rolls (+0) and gain a bonus equal to their HD to damage (+2) against evil/good foes. The smite persists until target is dead or the celestial/fiendish creature rests.
