Stack Plus Mod Wiki & Guide

Open your inventory, then access Mod Menu (usually by pressing a hotkey or finding it in your pause menu), locate Stack Plus Mod in the list, and click its settings button to open the configuration screen.

The global stack limit sets a default maximum for all items at once, while individual item rules let you override that default for specific items—for example, keeping diamonds at 64 while stacking dirt to 1 million.

By default, tools, weapons, armor, and shields stay unstackable to prevent issues with durability, but you can enable stacking for them in the individual item settings if you want.

The 99+ format is a display shorthand to save screen space; your actual item count is still tracked fully and shown in the item's tooltip when you hover over it.
