Inventory

Users store their unused RPG items in their inventory, which can hold any number of items, but has a weight limit.

If a user's inventory is overloaded, the user will not be able to perform actions that result in the acquisition of new items, such as opening loot boxes, making purchases from the in-game marketplace, or bringing in an item from NFT.

To empty inventory, any RPG item can be scrapped for Essence, or a user can put items up for sale on the in-game marketplace, or take rarer (C,B,A) items out of inventory as NFT to the blockchain wallet.

The count of available marketplace slots is limited, while to withdraw an item as NFT a fee should be paid in Gold. It costs 100 Gold ($1) to withdraw a C item, 300 Gold ($3) to withdraw a B item, and 900 Gold ($9) to withdraw an A item.

The weight limit of the newly created character is 1 kg, and it can be further increased by adding more attribute points to the Inventory attribute - each point increases the limit by 1 kg. For example, if the Inventory attribute has 15 points, the weight limit will be 15 kg.

The formula for the inventory weight limit is as follows: $WeightLimit_{grams}=1000*(Inventory+1)$

Each point in the Inventory attribute causes the weight limit to grow linearly, while the weight of items grows as a root of the level, i.e. more slowly. Therefore, as the inventory grows, each new item takes up a smaller percentage of the total weight limit.

As a result, users are motivated to increase their inventory weight limit not only to hold more rare and high-level items, which weigh more, but also to be able to hold a larger total number of items.
