You can leap to attack enemies from unexpected directions.
Benefit: You may make an Acrobatics check as part of a charge attack. The DC of this check is 16 if the target of your charge attack is a Medium or smaller creature and increases by +8 for each size category larger than Medium. If successful, and your attack hits the target, the attack automatically is considered a critical threat. If the target falls (either dead or unconscious) as a result of this attack, you can continue moving in a straight line to the extent of your remaining available movement.
