Monster Manual II
Improved Grab (Ex): If a hook horror hits an opponent that is at least one size category smaller than itself with both claw attacks, it deals normal damage and attempts to start a grapple as a free action without provoking an attack of opportunity (grapple bonus +18). If it gets a hold, it automatically hits with its rending bite attack the same round. (This replaces its normal bite attack for that round.) Thereafter, the hook horror has the option to conduct the grapple normally, or simply use its claws to hold the opponent (-20 penalty on grapple check but the hook horror is not considered grappled). In either case, each successful grapple check it makes during successive rounds automatically deals damage for both claw attacks and a rending bite.
Power Sunder (Ex): A hook horror attempting to strike a foe's weapon or shield does not incur an attack of opportunity. On a successful power sunder attack, a hook horror deals double damage.
Rending Bite (Ex): A hook horror can automatically bite a grabbed foe for 3d6+10 points of damage.
Blindsight (Ex): A hook horror emits high-frequency sounds, inaudible to most other creatures, that bounce off nearby objects and creatures. This ability enables it to discern objects and creatures within 60 feet. The hook horror usually does not need to make Spot or Listen checks to notice creatures within range of its blindsight. A silence spell negates this ability and forces the hook horror to rely on its weak vision, which has a range of 10 feet.
Light Sensitivity (Ex): Exposure to bright light (such as sunlight or a daylight spell) imposes a -2 penalty on a hook horror's attack rolls.
Skills: A hook horror receives a +8 racial bonus on Hide checks when in subterranean areas.
Hook horrors attack in groups, using their climbing skills to ambush foes from above. They fight cooperatively and work together against the largest and best-armed opponents. Hook horrors use their arm hooks to trip foes. If a battle goes poorly, they retreat by scaling walls.
