# Heroes Heroes in DeFi Kingdoms are utility-based NFTs with a variety of uses. Heroes can be paired to [Summon](/gameplay/heroes/summoning.md) more Heroes, whose classes, [stats](/gameplay/heroes/stats.md), and [rarity](/gameplay/heroes/rarity.md) are partially determined by the two Heroes used to infuse the Summoning Crystal. Heroes can engage in [Profession Quests](/gameplay/quests/professions.md) to earn JEWEL, CRYSTAL, JADE and in-game resources, as well as increases to the relevant profession skill and experience toward the next Hero level. Once Heroes reach an experience threshold, they can [level up](/gameplay/heroes/leveling.md) at the Meditation Circle. Eventually, Heroes will be able to participate in further [Quests](/gameplay/quests.md) to gain loot and experience, including PVE quests in which they battle enemies. The [Tavern](/gameplay/locations/tavern.md) hosts the NFT Agent, who can assist with buying and selling Heroes, as well as renting them out for use in the Summoning [Portal](/gameplay/locations/portal.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.
