I have thought about trying the LR mod for a long time now, and have finally decided to do it. Right now I´m playing trough the whole series starting at BG1, so it´ll still take a while until I get to ToB.

I just have a few questions about the mod before I get it. I´m sorry if the answers to some of them are written down somewhere and I've simply missed them.
First of all, are all NPCs compatible with Irenicus, or will some of them start fights or leave the group if I bring them together? It would be pretty irritating to bring a character through all of SoA only to have them leave me once I get to ToB. I've been thinking about romancing Jaheira this run, but I know she doesn't exactly like Irenicus, will there be any problems between them that the PC can't settle. Are there any other char I should think of who I can´t take in my group?

Also is there any list of what other mods are compatible with LR? Or could someone tell me if there should be any problems with the mods I´m using. Right now I have:
- Ascension
- Kelsey
- Banter Pack
- Unfinished business
- Turnabout
- Oversight

The thing I´m most worried about is probably the Improved(tougher) Sendai part of Oversight. I knew there used to be problems with a few of the Improved bosses from Ascension. I know nothing of scripting/modding so I have no idea what consequences the mod might have. Is there anyone here who has played LR with Oversight's Improved Sendai fight and can say if it works or not? Or does anyone know if it should work.

I also didn't completely understand the stat requirements for getting Irenicus. Would a char with 14 int and wis and 18 cha be able to get him(and get the good ending)?
