Don't know where i put the first part of the Hoppulus fight. But its pretty the same like the last 40%, just md the adds and focus one mob with a hammer to kill all with it.
The last boss was one of the shitty combs, so other will be much easier. Just keep your pet on the boss so u don't get any bolts in your face.
