Hello! So i have been trying to make a mod that adds plant fiber to minecraft 1.16.5 (i believe there are mods that add plant fiber but not for 1.16.5) but the problem is that i want to modify the loot table of grass to always drop plant fiber but also keep the vanilla drops. Most common answer i have seen is GlobalLootModifiers. But my tiny brain cant understand any tutorials. So any help is appreciated.
