Rend (Ex): If an octopin hits with both tentacle claw attacks, it latches onto the opponent's body and tears the flesh. This attack automatically deals an additional 2d8+6 points of damage.

Slowing Gaze (Su): Slow for 1d6 rounds, 30 feet, Will DC 18 negates. The save DC is Charisma-based.

Penetrating Sight (Su): An octopin can see through up to 2 feet of wood, 6 inches of stone or metal, and 1 inch of lead as if it were only a ghostly image. Octopins are immune to visual figments (such as major image) and glamers (such as invisibility). It still requires line of effect to a target in order to utilize its slowing gaze.

Skills: An octopin has a +8 racial bonus on Climb checks and can always choose to take 10 on a Climb check, even if rushed or threatened. Octopins have a +4 racial bonus on Search and Spot checks.

The octopin favors attacking from above, climbing down walls to surround and surprise its prey. It relies on its slowing gaze to hinder opponents while it tears them to pieces with its deadly tentacle claws.
