When update first came out and it was a Full Moon, I had some gnarly 13+ HP drains going on.

Now the Enaspir sucks something fierce. I have to deal 100+ damage to receive even 1 MP drained from MP based monsters. This was at about 50% moon heading towards new.

I have a suspicion that rising moon gives endrain, falling moon gives enaspir. Or it could be close to full moon is endrain, close to new moon is enaspir.

I don't mind Fenrir following the moon's cycle and I personally enjoy the roleplay aspect of the game. But it would be nice if enaspir could be useful...
