You can feint to disengage from combat.
Benefit: As a standard action, use Bluff to feint against an opponent. Instead of denying that opponent his Dexterity bonus to AC, a successful feint allows you to move up to your speed without provoking an attack of opportunity from the opponent you feinted for leaving the square you start in.
