[Elsword INT] 642% EXP Knight Emperor 16-2 Solo (Before 03.27.24 balance patch)

The house buff ran out before the dungeon result screen so the EXP gained was lower than usual. Normally, I'd gain about 340m EXP per run.
Can be improved further if I reforge the rest of my armors to R21. But the balance patch would've come already, so I cannot record another video to compare between the same Mod Double Slash.
