Keep your aiming reticle on an enemy and quickly flick the Circle Pad to dash around the enemy. This is the perfect way to get behind enemies that are impervious to attacks from the front.
Dash-around acts as a close-range dodge against melee attacks. For aggressive players using weapons like claws and blades, the dash-around can allow you to maintain pressure on an opponent who is mounting a skilled defense. It can also be a way to turn a situation around on your attacker and go back on the offensive. As with dodging, the dash-around consumes stamina, so make sure not to use this excessively.
