These creatures are aggressive and territorial hunters, with arms reaching 10 feet or more in length. Their tentacles are studded with barbs and sharp-edged suckers.
An opponent can attack a giant octopus’s tentacles with a sunder attempt as if they were weapons. A giant octopus’s tentacles have 10 hit points each. If a giant octopus is currently grappling a target with the tentacle that is being attacked, it usually uses another limb to make its attack of opportunity against the opponent making the sunder attempt. Severing one of a giant octopus’s tentacles deals 5 points of damage to the creature. A giant octopus usually withdraws from combat if it loses four tentacles. The creature regrows severed limbs in 1d10+10 days.
Improved Grab (Ex): To use this ability, a giant octopus must hit an opponent of any size with a tentacle attack. It can then attempt to start a grapple as a free action without provoking an attack of opportunity. If it wins the grapple check, it establishes a hold and can constrict.
Ink Cloud (Ex): A giant octopus can emit a cloud of jet-black ink 20 feet high by 20 feet wide by 20 feet long once per minute as a free action. The cloud provides total concealment, which the octopus normally uses to escape a losing fight. All vision within the cloud is obscured.
Skills: A giant octopus can change colors, giving it a +4 racial bonus on Hide checks. A giant octopus also can squeeze and contort its body, giving it a +10 racial bonus on Escape Artist checks. A giant octopus has a +8 racial bonus on any Swim check to perform some special action or avoid a hazard. It can always choose to take 10 on a Swim check, even if distracted or endangered. It can use the run action while swimming, provided it swims in a straight line.
