Fat Stacks
by CooledBeans
Fat Stacks raises the stack size of most items to 99, including many items that previously stacked only to 16.
What it does
Most items in the game can hold up to 99 per slot instead of their vanilla limit, including many items that previously stacked only to 16. The change covers items found in storage blocks, dropped on the ground, sold by villagers, or crafted in larger quantities. Fat Stacks requires the server and is published for Fabric, Forge, NeoForge and Quilt, with builds covering 1.21.4 – 1.21.6 and the latest file targeting 1.21.6. Players join without installing it, and the client may add it as an optional extra.
