do i have to have both classes at once at lvl 20? or just have gotten a certain class to 20 at one time.
as f2p game only has us owning one class at a time.
Once you die with one of the required level 20s, it will be removed off of the "Requirements"
Say you want a paladin, and you've managed to get a level 20 knight. If that character dies or is deleted, you only need to make a level 20 priest and are then free to play paladin if you have another slot available/die.
