reminder: Michael, if you can, please upload your savegame on some file host site. It's better than nothing, and it would save me hours of playing anyway. It's not perfect, but if others can't help more, I'll be grateful anyway.
Well, I'm not Michael, by I am a Priest, so here:
http://ul.to/7iidtxgg My Priest character is in level 4 of the Coliseum.
End of Act 2, before exorcising Francesca. Only side quests left are: obtaining chalice for alchemist and clearing the basement of the cursed tower in wastelands.
Bare in mind that I never wasted my magical boxes on frivolous matters and did a lot of exploring, so I'm a bit more powerful than the level (35) suggests.
There's Exile and Lightning, so have fun!
