A small data pack that gives some mobs a new loot table
Bats: Drop 1-2 leather
Chicken: Always drop at least one feather
Cow: Always drop at least one leather
Drowned: Have a small chance of dropping a nautilus shell and a even smaller chance of dropping a trident even if they don't spawn holding one
Shulker: Always drop 2 shulker shells. You can't get less or more than 2, not even with looting
Silverfish: Drop 1-3 iron nugget
Turtle: Always drop at least one scute on death
Wandering Trader: Don't like the trades? Now they drop 1-3 emeralds upon death!
Zombie Villager: Usual loot table with an addition of 1-2 emerlads on the drops
Witch: Now they drop more potion-related items. The full loot table is: glowstone dust, sugar, gunpowder, redstone, spider eye, nether wart, fermented spider eye, blaze rod, ghast tear, fermented spider eye, magma cream, golden carrot and glistering melon slice. Now you have a reason to go and look for some witch huts!
This is my first data pack, so it's very simple, but it should work just fine. Please report any bugs and suggestions you may have for further improvement of the pack!
