Your sensitive twisting movements make you difficult to anticipate combat.
Benefit: You gain a +4 bonus to CMD against trip combat maneuvers and on Acrobatics checks and saving throws to avoid being knocked prone. While using the Snake Style feat, whenever you score a critical threat with your unarmed strike, you can make a Sense Motive check in place of the attack roll to confirm the critical hit. Whenever you score a critical hit with your unarmed strike, you can spend an immediate action to take a 5-foot step even if you have otherwise moved this round.
Normal: You can take a 5-foot step only if you have not otherwise moved this round.
