^ wow, that's sounds hard.
I found the Endboss almost too easy, when the three dragons appeard I really thought this is it, I'm done for.
He never managed to kill me, but my group was already very high leveled (maybe even maxed out, I can't remember) so it was a piece of cake.
Can't even remember that he used status effects.
I did him on the first try, something that rarely happens to me in a game, it was almost disaapointing.
