Right, sorry for the newbish question, but I just tried to log on and play some multiplayer on Sacred, but when I go to do it, I don't see a way to use the Battlemage from my single player quest.
Do you have to start a new character especially for multiplayer, or is there some way to use the single player file that I have overlooked?
Any help would be appreciated! :)

I can't remember if the sacred servers are closed or not but I'm leaning towards yes. This means you will have to make a new character. You can test this out though by going into single player and exporting your character, This is done either from the character selection screen or actually from within the game from the menu, again its been a long time so I can't recall which. Once you make a character in multiplayer you could see if you can import him into that character screen.

Awesome! Guys thank you both so much.
You have to load the single player game up and then export, pick a slot, quit, load the multiplayer and go from there.
Thanks for the prompt responses also! :)

No problem. Have fun :)
