Strategy
As an another superboss that is an Angel, Eden is subject to the same weakness as every other Angel superboss: Holy Skills require mana to work. The second you drain Eden's mana to 0, she loses all her auto hit skills and can only use Pleasure and Physical attacks, which Waning Moon Dance will null completely. As such, the only issue is draining the mana in the first place, but once you do, Eden becomes useless. This also prevents the otherwise dangerous Illusion Fantasy Dance, which is one of the few current skills that grants any form of Auto Hit Evade, which means she CAN evade an Auto Hit skill/attack... or that dispel you were going to use to dispel Illusion Fantasy Dance. So, try not to drag this fight too long if you cant drain her mana in time.
