Healing Angel Bela! That decreases your healing ability...

It was to be expected to follow the same idea of rare encounters in the limited time quests.

10878 damage (after factoring in 50% water damage reduction) with CD4.  Her (unevolved) card really does have a RCR of zero too.  In general, Hogle's quest is harder than Lahair IMO due to a somewhat harder lineup of enemies, and this girl can whoop your ass if you don't come prepared with a damage reducer or very high ATK skills.

Her active skill is to enhance water ATK.  Not too surprising.  What is surprising is that her evolved form has NEGATIVE RCR, meaning you will actually lose healing as you level her, equal to her current level minus one.  So troll.
