I wouldn't say implement Mondshine just yet just to get to lvl 145 from 140. Instead increase the xp you need at sorcs at such a level so it's slightly easier to gain, or widen the Monsters you can kill to gain xp and level from 120+ because there are caves and areas that will probably be never touched due to the lack of xp given by the monsters in these caves /areas.
wooden keys should also be narrowed down to a level where it's slightly harder to get, since everyone has them. they make tokens look like nothing and made almost completely useless in the game.
