Upgrading
Tool upgrading lets Architects increase the rarity tier of a tool - improving its stats, efficiency, and durability. This system adds long-term progression and strategic decision-making to crafting.
Upgrading Path
Tools must be upgraded one rarity tier at a time:
Common → Uncommon → Rare → Epic → Legendary → Mythic
You cannot skip tiers.
Upgrading Cost
Each upgrade attempt requires a Crystal cost and has a success chance. The higher the rarity tier, the more crystals are required - and the lower the success rate.

Final Success Rate: 45.68% (40% + 1% + 0.64% + 1% + 0.94% + 2% + 0.10%)
Upgrade Risks
On failure, the tool remains at its current rarity
On failure, offered Tools are returned
⚠️ On failure, Crystals Donations and URRs are consumed regardless! ⚠️
The feature is optional - Architects can still craft higher rarity tools directly (rarely), or salvage and retry
*Failed Upgrades grant soul-bound Divine Favor Tokens for each Crystal used. One Divine Favor Token can be used for the Donation Boost instead of SUI. Divine Favor Tokens also have other uses in the game, mostly to boost chance-based events in the Architect's favor.
