Fusion Calculator

Estimate the total gold needed to fuse an item to a target tier. The estimate compares a perfect run, an average run with a 65% success rate, and a maximum-cost run with a 30% success rate.

Market price of one tier 0 item in gold.
Market price of one sliver in gold.
Classification determines tier limit and fusion cost.
Maximum tier for this class is 10.
How this is calculated
  • Every item starts at tier 0. Fusing two identical items of tier T creates one item of tier T+1.
  • Fusion costs depend on classification and the tier transition.
  • An Exalted Core costs 50 slivers and is used when either core option is selected.
  • The 100% column assumes every fusion succeeds, with cores consumed per attempt as selected.
  • The 65% and 30% columns show expected total costs for those success rates, including the chosen core costs.

Convergence Fusion

Convergence Fusion

Convergence Fusion fuses different items of the same body slot at the same tier into one item of the next tier. The result is guaranteed, but the gold cost is substantially higher than regular fusion.

The tier your item is at now (0–9).
The tier you want to reach (1–10).
How this is calculated
  • Each step from current to target tier requires a food item of the same tier as your item at that step.
  • The sacrifice item price for each step is set in the inputs above (defaults provided for tiers 1–9).
  • Convergence fusion always succeeds — no Exalted Cores or slivers are needed.
  • The total is the sum of all food item prices and convergence gold costs across every step.
