You guys said 20 lord-> 20 Cavailer -> 20 paladin -> great lord so I finally got him level 20 he starts off as lord already when I first got him so him being at lord 20 now I reclass back to lord? Now or does it mean I go cavailer then paladin then great lord? Just confused because hes lord 20 now do I go lord to lord or just promote to cavailer now? I know it's super confusing to ask like hes already started out as lord so I dont need to bring him back to lord again right?? I'm just trying to get better understanding
