Equipment in Ukiyo is graded by rarity, with increasing base stats depending on its tier.
Tier 1 - Common
Tier 2 - Uncommon
Tier 3 - Rare
Tier 4 - Epic
Tier 5 - Legendary
Most equipment in Ukiyo can be upgraded using power up stones. The success rate of a given enhancement is determined by the item's tier (rarity) and current level of enhancement.
High level equipment enhancement will necessitate an upgrade fee, which can be paid with either Ukiyo tokens or magical shards, depending on the level of enhancement. This is one of the key token utilities in the game that will incentivise players to use their earned tokens to enhance their character. Players who do not upgrade their equipment will reach a plateau, preventing them from progressing their character and experiencing late-game content.
