As per title.

It's something I should know, maybe, however the entirety of the answer has eluded me. What is the HIGHEST POSSIBLE exp bonus you may have in the game?

I mean, I know you have 50% rested exp, 3% bonus from food, 50% from having a lvl 50 class, for a grand total of 103% bonus. Now, is there anything ELSE you can have, or is 103% the hard cap considering the current possibilities?
