It seems like the mob encounter is rolled when a new frame appears, and using this i could spam eat a bunch of food to freeze the game and then click attack really fast when a rarer mob for example: the orc shaman appears to make sure i kill like 40 of them until the next frame loads. This became sort of a nice workaround when i had killed >1000 skeletons and needing those last rats.
I also noticed that the game lags almost nothing at all when no weapon is equipped, but any weapon at all made clicking freeze the game immediately =w=
Loved the game and would love to see more content added in the future! o/
