is there any way for the mega xp to just jump to the like level 27 or something?
you don't really want lvl 27 especially on Jaws of Hakkon when the enemies are leveled at 27 as well, even with 95% Melee DR and 50% Spirit DR and 25% Range DR they still take out a quarter of the health on my Warrior Characters a hit. and that's with Masterpiece Quality armor and the highest rating one can have. the current gear in the game isn't suited for such levels, it's okay for the normal run without Hakkon. but if you're going to do Hakkon, I suggest sticking to around 20 for that.
