I was talking with a friend and he said that Raphael has 4 forms? I think I just saw him change twice and I was playing on Tactician. Besides giving him legendary resistance to not having him fail for a tasha hideous laughter, make when his HP goes 0 at the first time he goes full again so you keep the 666 funny number that way and at the same time we can appreciate his fight at full potential.
Raphael can be rough right. I beat it at level 11, albeit i did it bugged, using hope divine intervention got her instant killed. He has 2 forms, one from ascended and normal.
