# Items ![](/files/GBBsSTejTsy1U9sWrJ9i) Items in the Nine Chronicles world are the main way for a character to increase their power and progress through the increase in difficulty stages of the Campaign, as well as challenge strong opponents in the Arena. Every equipable Item in the Nine Chronicles world is a unique NFT (Non-Fungible Token) over which the players have true ownership. Any item that a player possesses can be upgraded, bought, and sold in the shop. Items in the Nine Chronicles World are divided into: * [Equipment](/introduction/intro/items/equipment.md) * [Grimoire](/introduction/intro/items/grimoire.md) * [Rune](/introduction/intro/items/rune.md) * [Consumables](/introduction/intro/items/consumables.md) * [Materials](/introduction/intro/items/materials.md) --- # Agent Instructions: Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.
