Dont PM me, im not here to help!
There's a restriction with multi-classing of druids, monks and paladins. A character may change from/to any of the above, but once you leave the path of the above, you are never allowed to return to it. Any change from one of these classes should involve a Character Development Quest. The rules for character development quests are found here:Character Development Quest Rules and a brief synopsis further down in this document. For example: You cannot submit a 5/15 Paladin/Fighter as CDQ rules state no CDQs before level 10, but you can submit a 10/10 Paladin/Fighter. You begin as a paladin; at level 10 you MUST have a CDQ (Character Development Quest) run to become a fighter. From that point on you are never allowed to return to being a paladin unless the character submissions team approves it, which will only do under extreme circumstances that must include another Character Development Quest to return to your previous path. You could also begin as a fighter, but you would still need to have a CDQ run at level 10 to move into Paladin, as that would not be granted at creation. There is always the possibility of failure with a CDQ.
