Inventory

Materials stack 25 high in each inventory slot, while other items typically stack 10 high.

The in-game inventory has a soft-cap at 28 inventory slots. This number can be expanded through the use of rare equipment.

Items can stack in the same inventory slot if they are the exact same item. For example, like all materials, coal ore can stack 25 high within each slot. However, fine coal ore will not stack in the same slot as a normal coal ore, as they are not the same item. If you have 13 coal ore in your inventory and receive a fine coal ore while mining, it will occupy a new inventory slot. Crafted items and tools can stack 10 high within each slot, while consumables can stack up to 20. The amount of inventory slots you are currently occupying can be found in the bottom-left corner of the Inventory Screen.

Players can drop items from their inventory at any time by selecting a stack and using the UI to do so with the button that appears at the bottom of the screen.

For maximum power-leveling efficiency, you can also multi-select items in your inventory to drop, select, or bank them (that last one only if you are in a location with a bank). Long-press a single item to open up the multi-select UI, and continue tapping stacks to add them to the current selection.

Over-encumbered

Going above the soft-cap of 28 inventory slots will enforce global work efficiency penalties on your character. At 29/28 inventory slots (unless using inventory expanding equipment) this penalty is not severe, but it quickly slows your character down as you get into the low 30s. You will never slow to 0% progress, but you will eventually reach -99% work efficiency at 33/28 inventory slots occupied. It’s best to keep your inventory under the soft-cap limit.

The scale of work efficiency penalties for being over-encumbered goes as follows:

Items Extra	Penalty
1	-30%
2	-50%
3	-70%
4	-90%
5+	-99%

Treasury

On the bottom-right of your inventory screen, a button to access your treasury can be located. The treasury holds any chests that you find on your journeys. These chests do not occupy inventory space until you open them and receive the items that they contain. It’s easiest to open these at a bank so you can immediately bank the items gained, but it’s also possible to open these out and about, just be careful of going over the inventory soft-cap!
