I have a party of 5 and want to introduce a homemadecharacter, is it possible for me to do this using shadowkeeper? Or some other manor? And how can this be done! Thanks!

what exactly do you mean? do you have 5 custom-made characters, and want to make another one, or do you have 1 PC, 4 NPCs, and want to add custom character?

anyways, i think i may be able to help. roll up a character in the "premade char" section in multiplayer. then copy your savegame folder from the "save" to the "mpsave" folders in your BGII directory. load the multiplayer game, add your custom character, and save, then quit. then move your folder back to the "save" folder from the "mpsave" folder and you should be able to do fine.

And if you don't have internet(...) can you do this via SK?

the method given above doesn't require the net, just tell it to open a TCP/IP game and choose host
