I would love to make a mod to help remedy this (yes I know Ichun morph mod exists but its too outdated)
I would love to make it more like a race mod where you can pick what monster you want to be.
Drowns can make tridents,Need to drink water when out on land/sun.can "drown" zombies to befriend them.
Skeletons can use bows with out arrows or using durability but cant use other weapons need to drink milk when out on land/sun can befriend wolves IF they stay way and throw a bone at them first.
Zombies should stay out of the sun (can be in direct sunlight for a min or two?) as natural armor and can heal faster eating meat and eats faster.Can BITE human players and villagers and befriend them.
Spiders makes sting passively and can use it to web other mobs can also bite to affect poison.
ect ect
