How to gain extreme amounts of ap/exp in new game+

worked on ps5, most likely works on pc too

the trick

Ok so basically you will want to use chapter select to enter hardmode and do the quest "my white haired angel" or whatever and then reach the battle where the queen bee spawns, bees give tremendous amounts of ap and exp and the queen bee spawns them. Once you reach that place just kill the regular bees and avoid hurting the queen bee.

Quickly you will gain a tremendous amount of exp/ap and you can just go back to chapter select to do it again once she dies.
