if you are lvl 19 warrior and do betrayer quest to the good side then become a paladin you should be able to go over to the dark side *** a paladin ? or am i wrong.. it must be some quest that makes you evil agian..
Once you get past lvl 18 you can no longer do the betrayal quest. So no, you cannot become a paladin and then betray (again). Theoretically, Iguess you could do the betrayal quest as many times as you want as long as you do not hit lvl 18.
Why would a paladin become evil or a shadowknight become good?
while I'm all for people playing games in a way that most suits them, they do have to have some limitations on it to support the story line of good vs. evil.
Even in Pen & Paper D&D if you had an alignment change it was a big deal...it shouldn't be something you can change on a whim.
