Your technique is deceptive to any creature, even those that fight in an instinctual or unthinking manner.
Benefit: You no longer take a penalty to your feint check for feinting against a non-humanoid target. Feinting a creature of animal Intelligence (1 or 2) now imposes only a -4 penalty. You can feint a creature with no Intelligence score, although you have a -8 penalty when doing so.
Normal: When feinting against a non-humanoid you take a –4 penalty. Against a creature of animal Intelligence (1 or 2), you take a –8 penalty. Against a creature lacking an Intelligence score, it’s impossible.
