• Improved Grab (Ex): To use this ability, the xill must hit with one or more claw attacks. The grapple check has a +2 bonus for each claw that hits. If it gets a hold and maintains it the next round, it automatically bites the foe at that time. The bite deals no damage but injects a paralyzing venom.
• Paralysis (Ex): Those bitten by a xill must succeed at a Fortitude save (DC 14) or be paralyzed for 1d4 hours. Barbaric xills secrete enough venom to bite two opponents every 6 hours, while their civilized cousins can bite only once per day.
• Planewalk (Su): These planar travelers like to slip between the folds of space to attack enemies as though from thin air. They can cross from the Ethereal Plane with a move action but take 2 rounds to cross back, during which time they are immobile. As a xill fades away, it becomes harder to hit: Opponents suffer a 20% miss chance on the first round and a 50% miss chance on the second.
• Implant (Ex): Xills lay their eggs inside paralyzed creatures. The young emerge about 90 days later, literally devouring the host from inside. A remove disease spell rids a victim of the egg, as does a successful Heal check (DC 20) by someone with that skill. If the check fails, the healer can try again, but each attempt (successful or not) deals 1d4 points of damage to the patient.
• Feats: A xill receives the Multiweapon Fighting feat as a bonus feat. With its Multidexterity and Multiweapon Fighting feats, it can attack with all its arms at no penalty as a racial ability.

Xill characters

Xorn

• Burrow (Ex): A xorn can glide through stone, dirt, or almost any other sort of earth except metal as easily as a fish swims through water. Its burrowing leaves behind no tunnel or hole, nor does it create any ripple or other signs of its presence. A move earth spell cast on an area containing a burrowing xorn flings the xorn back 30 feet, stunning the creature for 1 round unless it succeeds at a Fortitude save.

• Tremorsense (Ex): Xorns can automatically sense the location of anything within 60 feet that is in contact with the ground.

• Bay (Su): When a yeth hound howls or barks, all creatures except other evil outsiders within a 300-foot spread must succeed at a Will save (DC 12) or become panicked for 2d4 rounds. This is a sonic, mind-affecting fear effect. Whether or not the save is successful, an affected creature is immune to that hound's bay for one day.
• Trip (Ex): A yeth hound that hits with its bite attack can attempt to trip the opponent as a free action without making a touch attack or provoking an attack of opportunity. If the attempt fails, the opponent cannot react to trip the yeth hound.
• Flight (Su): A yeth hound can fly as the spell cast by an 11th-level sorcerer, as a free action. A yeth hound that loses this ability falls and can perform only partial actions.
• Skills: *A yeth hound receives a +4 racial bonus to Wilderness Lore checks when tracking by scent.

• Sonic Lance (Su): Every 2 rounds, an yrthak can focus sonic energy in a ray up to 60 feet long. This is a ranged touch attack that deals 6d6 points of damage to a single target.
• Explosion (Su): The yrthak can fire its sonic lance at the ground, a large rock, a stone wall, or the like to create an explosion of shattered stone. This attack deals 2d6 points of piercing damage to all within 10 feet of the effect's center. This counts as a use of the sonic lance and thus is usable only once every 2 rounds, and never on a round following a sonic lance attack.
• Snatch (Ex): An yrthak that hits a Medium-size or smaller creature with a claw attack attempts to start a grapple as a free action without provoking an attack of opportunity. If it gets a hold, it can fly off with its prey and deal automatic claw damage, though it prefers to drop victims from a height. It can drop a snatched creature as a free action, which deals normal falling damage if the yrthak is flying.
• Blindsight (Ex): An yrthak can ascertain all foes within 120 feet. Beyond that range it is considered blinded. Yrthaks are invulnerable to gaze attacks, visual effects of spells such as illusions, and other attack forms that rely on sight.
• An yrthak whose sense of hearing is impaired is effectively blind, treating all targets as totally concealed.
• Sonic Vulnerability (Ex): Yrthaks are affected by loud noises and sonic spells (such as ghost sound or silence) and are more susceptible to sound-based attacks, suffering a -2 racial penalty to all saves.
• Immunities: Yrthanks are immune to gaze attacks, visual effects, illusions, and other attack forms that rely on sight.
• Skills: Yrthaks receive a +4 racial bonus to Listen checks.
