An XX constantly mutters and whines to itself, creating a hypnotic effect. All sane creatures within 60 feet of the XX must succeed on a Will save or be affected as though by a hypnotism spell for 2d4 rounds. Any creature that successfully saves cannot be affected by the same XX's babble for 24 hours.
When the XX casts a spell with a verbal component, its babble special attack is negated during casting, and any creature already hypnotized by it is freed of the effect. This a sonic, mind-affecting compulsion effect. The save DC is Charisma-based.
Touch of Insanity (Su)
Each of a XX's incorporeal touch attacks deals 1d6 points of Wisdom damage (Will save negates). A successful critical hit causes 1d6 points of Wisdom damage and 1d4 points of Wisdom drain (instead of double Wisdom damage). A XX gains 5 temporary hit points for each point of Wisdom damage or drain. The save DC is Charisma-based.
Any creature that targets a XX with a thought-detecting, mind-control, or telepathic effect takes 1d6 points of Wisdom damage (no save), though the effect otherwise works normally.
