Inventory

An Inventory is a set of slots where items appear, or can be placed for storage.

Stacks
Each slot in an inventory can contain multiples of the same item type; such a grouping is known as a "stack". Each item has its own maximum per-slot stack value, indicated on the item's wiki page via "Max Stack". The Max Stack for reusable weapons and tools is only 1, whereas for consumable items it is usually between 30 and 250. Individual items from a stack can be removed using the right-click button, which can be held down to continuously remove items from the stack, or the left mouse button can be used to remove the entire stack at once.

Main inventory
The player's main inventory can be viewed and modified by pressing the ESC key (default). This is where items the player has picked up will appear, and can be accessed for use or removed. Generally the term "Inventory" when used on its own refers to the main inventory.

The main inventory consists of the following slots:
 * 10 Hotbar slots: These comprise the top row of the main inventory, and are where the current useable items appear. Any item can be placed here. Even items that are not useable can be placed here for storage.
 * 30 storage slots. Any item can be placed here.
 * 4 Coin slots where coins the player has picked up, or acquired via selling items, will appear. Non-Coin items can not be placed here.
 * 4 Ammo slots for storing Ammunition items. Ammunition can also be stored in other slots, but ammunition stored here will be used first, and ammunition items picked up will be placed here first. Non-ammunition items can not be placed here.
 * 1 Trash Slot for discarding unwanted items. Any item can be placed here.
 * 3 Clothing slots where helmet/shirt/pants items can be placed for wear. These slots are generally used for Armor. Non-clothing items can not be placed here, and clothing can only be placed in its appropriate slot, ie. Helmets in the Helmet slot.
 * 3 Social slots where Vanity items can be placed for wear. Armor and other items that normally provide functionality can also be placed in these slots, though they will have no effect other than appearance. Non-clothing items can similarly not be placed here, and clothing can only be placed in its appropriate slot, ie. hats in the Helmet slot.
 * 5 Accessory slots where equippable accessory items can be equipped. Non-equippable items can not be placed here.

Storage item inventory
Storage items have 20 inventory slots where the player can find new items or store excess items.

NPC inventory
NPCs who sell items each have their own 20-slot inventory where the items available for purchase are shown. Items sold to the NPC will also appear there, but only while the inventory remains on-screen; accessing the same NPC later will not show the sold items.
