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.

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.

Half Damage from Slashing (Ex): Slashing weapons deal only half damage to xorns, with a minimum of 1 point of damage.

All-Around Vision (Ex): Xorns' symmetrically placed eyes allow them to look in any direction, bestowing a +4 racial bonus to Spot and Search checks. Xorns can't be flanked.

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