🔡Tier Up(=evolution)

There are 5 tiers of buildings: common, rare, epic, unique, and legendary. To go to the next tier, you need level 1 lv building NFTs materials (= building demand) of the same tier. Since tier upgrades are based on chance, 1 lv building NFTs materials are consumed, and in addition to consumption, the 3 lv building NFTs you want to tier up can be destroyed (destructed building NFTs can be restored). To get to the next tier, $Lay 007 and $Orb for each building's level and tier are consumed. Tiering up also takes time.

If a building is successfully tiered up, building NFTs' Lay-Bours and Green Value will increase by 1 to a fixed value.

Rare Tier Building NFTs = Level 3 Common + Level 1 Common (material), with a chance of failure. Failure may also result in the destruction of a level 3 Common. If it succeeds or fails, the level 1 Common(material) is burned.

Epic Tier Building NFTs = Level 3 Rare + Level 1 Rare (material), with a chance of failure. Failure may also result in the destruction of a level 3 Rare. If it succeeds or fails, the level 1 Rare(material) is burned.
