Celtic Heroes

I have a few questions:

A.) what are the lvls of the bosses?
B.) exactly where to they spawn?(I know they spawn in Carrow and Sewers. I mean exactly where do they spawn in those areas.)

40 sewers unknown
90 in giant sewecrawlers, top left circle in sewers
140 carrow in one of the boggan caves
190 mord troll pit

Do you know that for sure, or just educated guesses?

There's a blog out that has names and general locations

That's Bitey's I believe. I was thinking they'd be like OW rare weapon mobs which apparently they aren't and they're just rare bosses, but idk and no one is being very helpful in saying much about them thinking we'll just have to wait and see for ourselves...
