after some testing after the level 30 xp changes, with no deaths i believe i can reach 1x in about 45 hours of playtime.
if reincarnates are 10% more xp per then by my calculations -
45+50+55+60+66+73 = 349 hours
and then ill be ready to play the game for real!
that is defintely a scary grind and i can understand why some have mixed feelings about it. i kind of doubt i will make it to the 6th reincarnation, but im actually really looking forward to trying it.
