Requirement: Agility 3, Endurance 3
You can retreat while attacking or lunge forward with an attack.
To retreat, you need to hit with either a light or strong attack, and before the strike is executed, press the jump key.
To perform a forward attack, it's similar. Execute a light or strong attack, then press the forward key and the jump key.
This type of attack consumes two more stamina points than it normally would.
