Open perk planner ↗Browse a recipe
The upgrade catalog lists the result, base success chance, ingredient groups and binding item for every recipe in the upgrade station. Each ingredient group is required. When a group lists alternatives, supply one accepted variant from that group.
Check your personal chance
The station displays your personal success chance. Ordinary recipes can receive a donator bonus. Selected recipes also track failed attempts and apply a capped pity bonus. The base percentage in the wiki does not include those player-specific modifiers.
What a failed attempt consumes
For ordinary chance-based station recipes, a failure consumes the binding item and retains the ingredient items. A successful attempt consumes the ingredients and binding item to produce the result. Read the actual confirmation before proceeding.
Fixed flail recipes
Ivandis, Blisterwood and Hallowed flails use fixed-cost exchanges. These have 100% recipe success and require their listed coin cost and materials. Keep a free inventory slot. The Hallowed flail requires a Blisterwood flail, 20 blood shards and 100,000,000 coins.
Other item systems
The upgrade station is not the same as every item attachment or item-on-item combination. Items may have separate charge, attachment and special-action rules. Do not assume a station recipe describes those systems.
