Quickest way to level up

As above

Outside of the super challenge battles and rank up events, best is Chapter 4: Prelude to the Empire, Hidden Temple, 10 tickets for the Dungeon giving 2600 EXP.

Quickest way is to beat extreme level on super challenge…Aren’t sure how much experience points is awarded but definitely in the range of ten of thosands…Coz i gain 1 lvl up immediately even though i am in my 80s already…

Extreme always gives 30k EXP. This is roughly equivalent to one rank in the early 80s. However in the late 90s, each rank starts taking somewhere around 45-50k

yes 90 is 50k
im at 93 now next level is 53k
