what happen if I use a trilogy keycode in my acc with factions?

I have been asking myself this for some time, I will get 8 character slots (plus the 4 I already have)? Or there will be only 8?, same with xun lai panels, according to wiki using complete collection gived only 2 more char slots if there was an existing campaign, but doesnt say nothing about trilogy, I won't loose my actual characters?

You get one bank tab per campaign and two character slots per campaign. I think EoTN doesn't give anything. You will not lose your existing characters.

you will get the other chapters that you dont already have added to your existing one, you will get the 8 total character slots (4 for the first chapter +2 for each additional one for a TOTAL of 8, yes eye gives nothing on that end). Basically it will look like you have only the trilogy on your account--so what that gives you is what your account will look like after you add it. It wont get rid of anything you currently have (I did this with a prophecies account---added the trilogy to it--and thats what I got).

Thanks guess I'll have to buy some char slots later xP, but is good to know I wont loose the stuff I have
