# Economy Sinks

As most games depends solely on increasing the player base to keep the economy afloat, we have different "mechanics" or sinks to incentive the players to re-invest into the game.

**NFT Repair:** 

As you might be aware by now, suits and weapons have a limit of uses until they can no longer be used, but you can easily repair them by going to the workshop and paying the required fee.

**Expedition Fee:**

Did you think that going onto expeditions was as simple as that? Well survivor you need to face the cost of such expedition from things like ammunition, fuel, crew, etc.

**Workshop Fee:**

Remember that you need to pay the artisans on the workshop to do the tremendous job of fusing your brand new suit. It is said that any tip you give them will make them work harder and you will obtain a higher rarity item.

***Note:** All the fees that are paid in Onyx and will be sent immediately to the token reward pool.*

With this we are looking to give an important use for the Onyx so players will always have the need to purchase or get onyx, keeping the main reward pool healthy.
