We have stated 6 different rarities to make sure the game economy remains sustainable. The first 2 rarities are Common and Uncommon. Dragons with these rarities will be virtual items: they cannot be bought or sold in the marketplace, but they will be vital to get better rarity dragons.
Rare, Epic, Legendary and Mythical rarities will be considered NFTs (Non-Fungible Tokens), all dragons with these rarities can be swapped in the Coinary Hub marketplace. All rarities will be available for all dragons, and will also apply to other items in the game, which will allow to consider them as NFTs and can be traded in the marketplace, too.
The level cap of a dragon will vary according to its rarity.
Common: level 20
Uncommon: level 40
Rare: level 60
Epic: level 80
Legendary/Mythical: level 100
Dragons will also evolve/grow on different level checkpoints depending on their rarity; and will also gain a small improvement on their base Stats, when they learn their "Passive abilities" every 20 lvls (Passive abilities are not yet implemented on the game)
