# Rarity System & Blockchain Classification All items fall into four rarity tiers. Each tier affects how the item looks, how valuable it is in gameplay, and if it can be minted as an SFT or NFT. #### Four-Tier Rarity Structure * **Common Items** – Basic functionality and power up; can be minted as Semi-Fungible Tokens (SFTs). * **Rare Items** – Enhanced visuals and power up; can be minted as SFTs. * **Epic Items** – Distinctive designs and power up; can be minted as SFTs. * **Legendary Items** – Outstanding visual effects and power up; minted as Non-Fungible Tokens (NFTs) with a limited supply set at the end of each season. #### SFT vs NFT Classification **Semi-Fungible Tokens (SFTs)** * Eligible items: Common, Rare, and Epic (excluding Reward Track items, Profile Pictures, and emoji™ Vocabulary) * Supply: Unlimited minting, letting the market control availability * Trading: Multiple identical items can exist and be traded individually **Non-Fungible Tokens (NFTs)** * Eligible items: Legendary only (excluding Reward Track items, Profile Pictures, and emoji™ Vocabulary) * Supply: Each item has a limited number of copies * Trading: One-of-a-kind assets with verifiable scarcity --- # 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.
