Snake Style (3.5e Martial Artist Maneuver)
From D&D Wiki
With Snake Style, strikes come fast and low, in retaliation to hits.
Level: Reactive 2
Description: While snake style is the active stance the martial artist deals double damage on all successful attacks of opportunity against an opponent. Snake style's effects are void if used against flying opponents, oozes, incorporeal creatures, or creatures immune to critical hits (with exception to plants and constructs, which snake style may be used against).
