Zelda Wind Waker: Darknut Fight Skull Hammer Only

Darknuts are basically kind of "free" in Wind Waker with parries and boomerang spam and the like but actually their armor does take damage, shown here with a horizontal Skull Hammer swing. (Vertical hits their helmet which is invulnerable to all but a sword parry.) I'm not sure entirely how it works; their armor seems to have their own health bar, however they take some residual damage after their armor is destroyed it seems. Either way this enables a pretty fun Skull Hammer only run. (Although it should be noted that you can still hit their weak point with the Skull Hammer to immediately destroy their armor.)
