NECRON?!?!
Sorry, he is quite hard, but it reminded me of this funny thing that happened once...

I had a friend over, and he wanted to see me beat Necron. So anyway, I got into the fight, expecting something hard. Guess what? He does grand cross... and it does a total of NOTHING!!! I had no status changes (I wasn't protected against half of them), and I think one person got hit for 200 damage!!! Then I beat him in the next round, with practically full health, in 5 minutes! Funniest thing that ever happened to me.

Anyway, Gizamaluke was quite hard for me, and Tantarian was annoying because I always had to do the battle with Freya, who you hadn't been able to use for ages, and was stuck at some low level. Oh, and definitely trying to steal things from bosses is the most annoying thing.
