Blood Drain (Su)
A blood sucker can drain the blood from a target within 30 feet. The target must make a Fortitude save (DC 12) or take 1d8 points of shadow damage and the squid is healed for that much. Blue mages may learn this ability as a 1st level spell (Knowledge: Arcana DC 17).
During a constriction, the blood sucker can heal half of the damage done from constrict.
Ink Cloud (Ex)
A blood sucker can emit a 10-foot-radius cloud of ink once per minute as a free action while underwater. This cloud provides total concealment. The ink persists for 1 minute.
A blood sucker can jet in a straight line as a full-round action. It does not provoke attacks of opportunity while jetting.
Water Gun (Su)
A blood sucker can shoot water out of its mouth towards a single target with an water projectile. The blood sucker must make a ranged touch attack (+5), if it hits, the attack deals 1d6+2 water damage and must make a Fortitude save (DC 12) or be inflicted with the Drenched status effect. Blue mages may learn this ability as a 1st level spell (Knowledge: Nature DC 17).
