Help on Gates of Madness!

Okay well, I have tried this mission countless times and I keep losing! I'm really starting to get upset about this and I would like to try and recruit some good players from here to help me! It would be really helpful if some people could help me. My character is a dervish by the name of Eli Lizt Eldenbroch.
Again help would be greatly apreciated!

the only "hard" part would be i guess shiro, but if u keep ur henchies back u "should" be fine, add an ss or sv necro in your group that would help.

Or are u having trouble with the portals?
