Msea's Exp Chair ;x

EXP storage, basically? That's pretty cool in certain scenario.

Let's say you're doing a Zakum run, but you're at 96% and don't wanna level without your INT equips, for HP wash. Store the EXP in your chair. Finish Zak run, wear INT equips, sit, level up. Win.

Of course, if it only lasts 1 day chances are you can't do that, so that's pretty crappy.
