Most common drops such as Gunpowder, Rotten Flesh, Bones ect. are dropped in quantities of 0, 1 or 2.
I personally find it a little bothersome if I don't get a drop I need due to bad luck, so this datapack makes it so that these mobs always just drop 1 of their common drop.
For example, a slain Zombie will always drop exactly 1 Rotten Flesh.
A slain Skeleton will always drop exactly 1 Bone and 1 Arrow. (Bow drop change is unaffected)
A slain Creeper will always drop exactly 1 Gunpowder.
The random drops added by looting are unchanged.
So killing a Creeper with a Looting 3 sword will make it drop 1 ~ 4 Gunpowder.
This datapack will override vanilla drop tables of certain mobs.
