A reddish octopus crawls along the beach. From its head, betweeen its eyes, eight long and thin spikes grow, seemingly easy to detach. Its arms are backed with barbs.
These sea creatures are relatively harmless, but like to annoy travelers at beaches and rivers by sniping at them from afar with their head spikes. They are however rather cowardly, and will attempt to escape if cornered. Unlike other octopuses, octocores are social creatures, and often form small “ambush” groups.
Improved Grab (Ex): To use this ability, an octocore must hit an opponent of any size with its arms 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 automatically deals bite damage.
Spikes: An octocore can shoot a single spike from its head as a standard action. This attack has a range of 120 feet with no range increment, dealing 1d4 points of damage plus 1/2 his Strength modifier. The octocore can launch only eight spikes in any 24-hour period.
Ink Cloud (Ex): An octocore can emit a cloud of jet-black ink 10 feet high by 10 feet wide by 10 feet long once per minute as a free action. The cloud provides total concealment, which the octocore normally uses to escape a losing fight. All vision within the cloud is obscured.
Jet (Ex): An octocore can jet backward once per round as a full-round action, at a speed of 200 feet. It must move in a straight line, but does not provoke attacks of opportunity while jetting.
Skills: An octocore can change colors, giving it a +4 racial bonus on Hide checks.
An octocore also can squeeze and contort its body, giving it a +10 racial bonus on Escape Artist checks.
An octocore 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.
