Drag (Ex): If a urophion hits with a strand attack, the strand latches onto the opponent's body. This deals no damage but drags the stuck opponent 10 feet closer each subsequent round (provoking no attack of opportunity) unless that creature breaks free, which requires a DC 24 Escape Artist check or a DC 20 Strength check. The check DCs are Strength-based, and the Escape Artist DC includes a +4 racial bonus. A urophion can draw a creature to within 10 feet of itself and bite with a +4 attack bonus in the same round.

A strand has 10 hit points and can be attacked by making a successful sunder attempt. Attacking a urophion's strand does not provoke attacks of opportunity. If the strand is currently attached to a target, the urophion takes a -4 penalty on its attack roll to resist the sunder attempt. Severing a strand deals no damage to the urophion itself.

Extraction (Ex): If a urophion begins its turn with at least one strand attached to a victim of Huge size or smaller that is adjacent to it, it can attempt to perform an extraction of the victim's brain as a full-round action. It must succeed on a bite attack, dealing normal damage. It then makes an immediate grapple attempt as a free action without provoking attacks of opportunity. If the urophion succeeds on this check, it tears the victim's skull open and devours its brain, killing it immediately.

Constructs, elementals, oozes, plants, and undead are immune to extraction. Extraction is not instantly fatal to foes with multiple heads.

Mind Blast (Sp): A urophion can discharge a devastating psionic attack in the form of a cone 60 feet long. Anyone caught in this cone must succeed on a DC 18 Will save or be stunned for 3d4 rounds. The save DC is Charisma-based. This ability is the equivalent of a 4th-level spell.

Psionics (Sp): At will - detect thoughts (DC 14), suggestion (DC 15). Caster level 12th. The save DCs are Charisma-based.

Strands (Ex): Most encounters with a urophion begin when it fires strong, sticky strands. The creature can have up to six strands at once, and they can strike up to 50 feet away (no range increment). If one of its strand is severed, a urophion can extrude a new one on its next turn as a free action.

Weakness (Ex): A urophion's strands can sap an opponent's strength. Anyone grabbed by a strand must succeed on a DC 19 Fortitude save or take 2d8 points of Strength damage. The save DC is Constitution-based.

Skills: Urophions have a +8 racial bonus on Hide checks in stony or icy areas.

Like a roper, a urophion hunts by standing completely still until prey wanders near. It can then use detect thoughts to pick out the best targets for immediate attack, which it launches with surprise.
