For the love of god, I cannot stress how important it is for you to practice using Eos on Obey. She will blow her AOE regen whenever a single person is under something like 80% HP and makes adds a nightmare in a couple of fights, as she grabs hate really easily from it and can screw up with positioning which is extremely important in a lot of fights.

I should also remind you to never use Medica II if you are expecting adds for the same reason. It's an amazing spell but you have to be very careful with it.
