Done on PS4 (not PRO) without SSD so loading screens adds some time.

There is definitely place to improve. Hammer is not the fastest weapon for speedrun, but still pretty efficient. For now its World Record Hammer Any% Colossal Task. Personally I don't think hammer will be best choice for any weapon world record, but sub 4:45 should be possible.

This are my timers for monsters (not included expedition monsters), No faints. Pretty bad RNG on Ajanath, but still good run.
