Fuse chance calculator
Enter three pets of the same species to estimate result weight, upgrade chance and Fuse price before consuming them.
Possible weight ranges
How to use it
Choose the same species for all three inputs, enter pet weight—not egg weight—and select every mutation on each pet. The three pets are consumed. A larger result is never guaranteed.
What changes the result
Weight is converted to internal Scale with Scale = ∛(weight ÷ reference weight). The three Scale values are averaged. Mutations change estimated income and price, not the modeled size chance.
Mutation price factor
No mutations: ×1. At least one mutation, with no pet holding two: ×2. Any input pet with two or more mutations: ×3.
Modeled estimate
The public source describes a reconstructed client model, not guaranteed server odds. This implementation is calibrated to its published Chicken, Stag and Nightflame examples. Displayed weights may be rounded; always confirm the live price before fusing.
