Artibus Features
Consistent Leather
Animals that drop leather will consistently drop a single leather item regardless of looting.
More Shulker Shells
End Cities are far apart, and the end is quite dull. Shulkers always drop at least one of their shells, and regularly drop both.
Silk Touch Vines
Vines can be collected with either shears or silk touch.
Zombie Nuggets
Zombies no longer drop iron ingots, but drop iron nuggets at a considerably higher rate.
