They can be found in caves, print/allocate or craft. * **Materials**** :** also called ingredients**,** they can be either mechanical or indigenous. The former corresponds to objects which most of the time come from units that were damaged/destroyed when they explored the caves. This category contains for instance mushrooms, insects, inert substances such as water and more. * [**Consumables**](/nbm-shadow-depths/overview/nft-battle-miners-official-wiki/vii-shadow-depths/games-logic/consumables.md) **:** those items are temporary bonuses that can be used during explorations. They can be crafted using particular ingredients/materials, printed, or imported. Consumables can also be mined using NFTM operations. * **Tokens** : One of the 4 Shadows Depths crypto tokens, also called ressources : [Fusium](/nbm-shadow-depths/overview/nft-battle-miners-official-wiki/iii-resources/fusium.md), [Actium](/nbm-shadow-depths/overview/nft-battle-miners-official-wiki/iii-resources/actium.md), [Minium ](/nbm-shadow-depths/overview/nft-battle-miners-official-wiki/iii-resources/minium.md)or [Constructium](/nbm-shadow-depths/overview/nft-battle-miners-official-wiki/iii-resources/constructium.md). Those Resources are useful all around the game to craft various items, perform upgrades etc.

General clone interface with the warehouse in the left containing various pieces of equipment, materials and consumables.

Each materials, piece of equipment or consumables bears its own rarity ranging from Common to Ultimate. Currently, 5 different rarities are present

Different rarities from COMMON (Blue, left) to ULTIMATE (Purple, right).

To preserve space, similar items can be grouped together into 'stacks'. Thus, a stack allows the storage of identical items into the same slot thereby saving space. Depending on the type of items, stacking follows a simple set of rules: * **Equipment**** :** Can not be stacked. Each piece of equipment will always occupy 1 slot. * **Materials**** :** Up to 5 similar materials/ingredients can be stacked together from start. This number can be increased by upgrading the [Material Compressor](/nbm-shadow-depths/overview/nft-battle-miners-official-wiki/vii-shadow-depths/spaceship/material-compressor.md) SHIP module and playing with a [Season Pass](/nbm-shadow-depths/overview/nft-battle-miners-official-wiki/vii-shadow-depths/seasons.md#season-pass) will make your clone start with this module lvl 3. * [**Consumables** ](/nbm-shadow-depths/overview/nft-battle-miners-official-wiki/vii-shadow-depths/games-logic/consumables.md)**:** Up to 200 similar consumables can be stacked together. * **Tokens** : While exploring, every resource is stacked in the clone backpack. Initially, up to 100 units of resource can be placed into one stack. Playing with a [Season Pass](/nbm-shadow-depths/overview/nft-battle-miners-official-wiki/vii-shadow-depths/seasons.md#season-pass) double this number and upgrading the [Molecular Compressor](/nbm-shadow-depths/overview/nft-battle-miners-official-wiki/vii-shadow-depths/spaceship/molecular-compressor.md) Module increase the stack limit even further. {% hint style="info" %} Once the exploration is done, resources collected during the mission are automatically transferred to the Corporate Leader's wallet. {% endhint %}
