Describe the problem. Be as specific as possible!:

Well, the Battle Mage Skill, Dark Aura, keeps cancelling out the HP Buff of Ancient Warding (Merc 4th Job Skill). I would understand if it cancelled out the % damage boost from AW (which it does not), but it cancels out the HP boost for some odd reason. It makes it difficult seeing as Mercs don't have the greatest HP, and the extra boost really helps a lot.
