Suggestions

1.20.1 on high difficulty (day 250 or 100 in my case) no matter how thorougly i tweak breaker chance and other settings (weapon chance, offhand equipment...) zombies almost never spawn with pickaxes. Maybe 1 in 100 (even though often main hand is empty).

In general i'd wish we could get better config options, like it's implemented in Enahnced AI where one can tweak chances for separate equipment. E.g. mobs get way to often ender pearls and flint and steel and axes whereas extremely rare tnt, fishing rods or pickaxes, i'd like to be able to influence that. I tried to compensate this pickaxes and fishing rod diversity with Enhanced AI, but it seems Improved Mobs mod for the most part just ignores Enhanced AI and single-handedly determines mob's equipment.

Solution

Copy paste Enhanced AI config's functionality XD.
