Fear (Su): A xilob looks so horrible that any living creature seeing it must succeed on a DC 14 Will save or become shaken for 2d8 rounds. A creature that succeeds at the save is immune to that xilob's fear aura for 24 hours. This is a mind-affecting fear effect. The save DC is Charisma-based.

Stench (Ex): A xilob exudes a terrible stench. Each creature within 30 feet (except other xilobs) must succeed at a DC 20 Fortitude save on its turn each round or take 1d6 points of Strength damage. Success means that the creature does not take ability damage that round but must make a new save for each subsequent round of exposure until it fails. Once a creature has taken Strength damage from xilob stench, it cannot be affected again by the stench of any xilob for 1d4 rounds. Thereafter, it must begin making a save for each round of exposure again. Exposure to the stench of multiple xilobs in the same round requires only one saving throw. The save DC is Constitution-based.

Backward Tracks (Ex): A xilob's backward feet impose a -2 penalty on all Survival or Search checks made to track it. A successful DC 20 Knowledge (nature) check negates this penalty.

Skills: A xilob has a +8 racial bonus on Intimidate checks.

Xilobs don't attack humans without provocation, although their action often invite the anger and hostility of their neighbors. When forced into combat, xilobs are relentless and unforgiving opponents. These giants like to exploit their frightful presence ability in combat, and they often try to terrorize enemies before engaging them.
