Strengthened Typhoon Kick is the first Wind Stance upgrade. Typhoon Kick knocks targets further and adds Stagger damage, giving you more room to keep attacking.
Kick a spearman away, then close the gap again with Spearbreaker's leaps.
Upgrades in this tree unlock in order, so you need Wind Stance first.
Spear Defense
Spear attacks that hit you during a Wind Stance attack are parried automatically.
Moon Stance
A stance for brutes: heavy attacks deal extra Stagger damage and disrupt brutes whatever their weapon.
Water Stance
A stance for shield users: heavy attacks deal extra Stagger damage to shieldmen.
