When creatures approach, a darktentacles typically uses its charm monster and hold monster powers first, concentrating these attacks on foes who seem to be physically powerful. Thereafter, it attacks anyone who comes within reach of its tentacles. If the darktentacles manages to grab someone, it uses its wall of force ability to keep any other opponents from lending the victim assistance.
A darktentacles can use only three tentacles at once against a Small or Medium-size opponent. Against a larger foe, it can use three additional tentacles for each extra 5 feet of face the opponent has, provided that it has the reach. Against a Tiny or smaller opponent, the creature can use only one tentacle. It can use a maximum of three tentacles against all foes in any single 5-foot by 5-foot area.
Constrict (Ex): With a successful grapple check, a darktentacles can crush a grabbed opponent, dealing 2d6+6 points of bludgeoning damage.
Improved Grab (Ex): If a darktentacles hits an opponent that is at least one size category smaller than itself with a slam attack, it deals normal damage and attempts to start a grapple as a free action without provoking an attack of opportunity. If it gets a hold, it can also constrict in the same round. Thereafter, the darktentacles has the option to conduct the grapple normally, or simply use its tentacle to hold the opponent (–20 penalty on grapple check, but the darktentacles is not considered grappled). In either case, each successful grapple check it makes during successive rounds automatically deals slam and constrict damage.
Spell-Like Abilities: 5/day—hold monster; 3/day—charm monster; 1/day—wall of force. Caster level 10th; save DC 11 + spell level.
Enhanced Multiweapon Fighting (Ex): This ability lessens the penalty for off-hand weapon use by 2 for primary and 4 for off hands, and by 2 for its slam attacks. Combined with the Multiattack and Multiweapon Fighting feats, this ability effectively negates all attack penalties for using one or more light off-hand weapons or all its slam attacks.
Tentacle Regeneration (Ex): An opponent can attack a darktentacles’s tentacles as if they were weapons (see Sunder). A darktentacles’s tentacles have 20 hit points. If the darktentacles is currently grappling a target with that tentacle, it usually uses another limb to make its attack of opportunity against the sunder attempt. Severing a darktentacles’s tentacles deals damage to the creature equal to half the limb’s hit points. A darktentacles regrows severed limbs within a day.
Weapon Use (Ex): A darktentacles of Large size can wield a melee weapon of up to Huge size in each tentacle. It is proficient with all simple and martial melee weapons.
Skills: A darktentacles receives a +4 racial bonus on Hide checks.

Replaced Multidexterity with Multiattack in feats entry. Rewrote the Enhanced Multiweapon Fighting special quality to account for lack of a Multidexterity feat.
