How to start end-game?

[EmptyFibers]

Edit : Btw (in case you don't know) try to do AK to cap the 300 mythology tomes you can get each week. They reset on monday so try to get the 300 before that, each run gives 40.

When you say resets..., does that mean the 300 you have set to zero? I'm no where near end game, but merely curious.
