Assuming it works the opposite of Bravery skill demerit then this skill will prevent the enemies from lowering your attack and the precious crit damage. Doesn't prevent the enemies from lowering card performance though.

You generally want to use the skill for 20% NP up or preventing the enemy from lowering your crit damage because not most mobs carry card performance down instead of damage down debuff.
