Alignment Drain (Su) A simpathetic that perches upon or otherwise stays in contact with a living creature for a full round feeds on its innate goodness (if any). For every round a simpathetic remains in contact with a creature, that creature must make a DC 13 Will save or have its alignment shifted one step toward chaotic evil (if it isn't that alignment already). A creature must be willing, unconscious, charmed, or otherwise immobilized to allow a simpathetic to perch on it. A simpathetic can do nothing else during a round that it drains alignment. A creature affected by this ability functions as if its alignment is naturally this new alignment, losing access to any alignment-dependent class abilities (like a paladin's spells and abilities). A drained creature's alignment gradually recovers, returning to normal at a rate of one step per week, while atonement or remove curse immediately restores a creature's natural alignment. The save DC is Charisma-based.

Blood Spit (Ex): Once per day, a simpathetic can make a ranged touch attack that deals 1d4 points of acid damage. Those struck must make a DC 10 Fortitude save or, in addition to the damage, be blinded for 1d4 rounds. The save DC is Constitution-based.

Plane Travel (Su) Through a complicated weeklong aerial dance, a flock of six or more simpathetics can transport half of their number to a randomly determined plane as per the spell plane shift.

Speak with Avians (Ex): Simpathetics can naturally communicate with any avian creature.
