Aura Saber - Guardian Skill

Emit a murderous fighting spirit. With a weapon (or bare hands for a Monk) radiating with light, pierce through opponents as though they are wearing nothing. Special attack that deals piercing damage and ignores the defense of the target.

While it looks flashy, the amount of Hate gained relative to damage dealt is lower than other skills, so it's not too good at controlling large groups of enemies. However, this is useful against groups of enemies that don't have very tough skins.
