User blog comment:Jimeee/Skyrim 1.9 beta update adds Legendary difficulty and raises level cap (Updated Apr 8th)/@comment-88.159.13.170-20130326151454

I don't know if anyone has found out yet, but is there a limit as to how many times the Legendary Skill can be used?

I raised my Smithing to 'Legendary 100', and I could upgrade it again to 'Legendary 2' and do it for a third time.

Couldn't go to 300 if I wanted to, all the materials I gathered were used up on the second run..
