Creates a special aura around the weapon that increases damage and ignores the targets DEF, but not his Flee. Aura Blade kind of adds Weapon Mastery type ATK regardless of what weapon is being used.
Aura Blade does not have any element, which means it can hit Ghost monsters even if your weapon does not have any element. This means that element endow does not gives Aura Blade's bonus.
The effect cancels when switching weapon.
This is almost a Weapon Mastery Skill, and thus almost carries those properties; for example, the damage gained from this skill bypasses defense, and is added at the end of all attacks
It is recommended that this skill is either left at 0 or maxed.
