You sure about that? I've been summoning everything and anything I can and the only bit of diffrence it makes is it makes sure I live about 5 seconds longer. I don't usually get level drained, although a few minutes ago I almost had her when she drained my main character down to level 3 and killed her with one hit. That doesn't usually happen to me though.
My characters are all level 10 or 11 apart from my amin character who is level 13.
The really annoying thing is that I did this about a week ago by pure luck, but my computer messed up and I lost the save.
Oh well, thanks for the help, I'm off to try again.
