What happens to xp once you are legendary arch wizard/witch?

What happens to xp once you are legendary arch wizard/witch? Does it just disappear, or does it turn into soul gems or something?

Not one user has reached that level yet, if you check the rank page then you'll know. It has 0.00% population. To conclude, no one knows yet unless you're ambitious and passionate enough to reach it

Uh, I think you're mistaken. Masmm has it, and so do a few other people...

Uh, if you knew about that then you could've asked them yourself, not to be rude though but you had a solution to your question. Also, i assumed that there was none since nobody ever tried to show up.
