# Economics of Chests
Anything on this page is subject to change throughout the development progress of the game. We will thoroughly test and validate any feature before it goes live.
Initially, there are 3 chest rarities (common, rare, legendary). The chest contains 1 NFT recipe. The rarity of the recipe is described in the table in the previous section.
Please note that chests can be obtained in the following ways Dungeon+ Purchase on the marketplace / Participation in special events

* Weekly quests
* Special events in the PvP arena
Each period (e.g., weeks or months), there can only be one series of chests dropped. Each chest series contains a different combination of unique items with different attributes and visuals. Hence, developers can phase in and phase out new gear and weapons in a drop. For example, chest series can look like this:
The rarity and number of unique items per chest is described below
Different weapons and gear have different features. One important element is that some gear/weapons can only be used on specific planets to mine specific resources.
