Class & Attribute System: Divide heroes into familiar archetypes (Warrior, Assassin, Mage, Archer). Each hero possesses base stats ($HP$, $ATK$, $DEF$, $CRIT$) alongside an Elemental Affinity system (rock-paper-scissors mechanic) to enhance strategic gameplay.

Rarity Tiers: Grade heroes into distinct tiers (Common, Rare, Epic, Legendary). Higher rarity directly translates to stronger base attributes and significantly higher Coin earning efficiency (Earning Rate).

Level Up & Ascension: Force players to reinvest the Coins they earn in-game to upgrade levels or “ascend” past level caps. This acts as a primary Token Burn mechanism to combat asset inflation.

PvE Mode (Campaign/Dungeon): Players send heroes to clear stage-based monsters or crawl through dungeons.

Rewards: Standard utility Coins (capped daily per account) and equipment upgrade materials.

Stamina/Energy System:Every hero possesses a capped daily energy pool (e.g., 20/20 Energy). Once exhausted, players can still play for fun, but they can no longer earn Coins. This strictly blocks automated 24/7 farming bots from crashing the economy.

In-game Marketplace: A decentralized peer-to-peer ecosystem where players can freely buy, sell, or auction Hero NFTs, weapons, and gear using the native game token. The platform charges a small transaction fee (e.g., 5%) to continuously replenish the game’s ecosystem treasury.
