I'm currently playing a 19th level Monk on Sarlona by the name of Regtur Edisnori. He has over 34,000 more XP than required to become 20th level. I'm holding off advancing to 20th to take advantage of the XP in some lower level quests that would be diminished or completely cut off to me if I advanced that one level.

My question is this. By not advancing to 20th, am I missing out on Epic XP or will the XP I'm accruing still count as Epic when I finally level up?
