Your aberration blood has driven you to begin consuming the brains of your enemies.
Prerequisites
Aberrant Bloodline, Tentacled Horror, any one other Aberrant feat, four total Tentacle mutations.
Benefit
Madness drives you to consume the brains of living creatures. After gaining this feat, whenever you make a successful grapple attempt with a tentacle, that tentacle is considered to be attached. If your opponent escapes the grapple, all cease to be attached. If the opponent wins a grapple check but does not escape the grapple (such as making a check to damage you), only one attached tentacle ceases to be attached.
If you begin your turn with all four tentacles attached and have your opponent pinned, you can make a special grapple check to attempt to extract the opponent’s brain. If you win the grapple check, the opponent must make a successful Fortitude save (DC 10 + 1/2 your Hit Dice + the number of Aberrant feats you possess) or die. If the opponent succeeds on the save, he takes 1 point of Intelligence damage for each Aberrant feat you possess. A creature with 0 Intelligence automatically fails its Fortitude save against this attack.
This ability can only be used against living, corporeal creatures that possess a brain and is not instantly fatal to any creature with more than one head.
