Plan your fusion.
Combine Deviations and traits, compare chances, and try possible outcomes.

Animals and furniture add a trait. Additional Deviations can change species odds and the trait pool.

How the planner calculates +
Species & traits
The parents define the species pool; matching material Deviations change its weights. A single trait copy starts at 50%; two identical copies reach 100% without competition. Different traits in one group share the chance by copy count. Clean material Deviations only boost a group without competing traits.
Rating model
Skill: 40% each on A and B, 10% on the higher parent +1, 9% on that value −1, and 1% on −2. Activity: 45% each on A and B, 5% each on A+1 and B+1. Ratings are capped at 1–5 and equal results are combined. This distribution is a planning model.
Scope
For standard fusion with three known trait groups. SCP stat traits, techniques, species codes, and special mutagen recipes are outside this calculation. Additional SCP skills prevent a material Deviation from counting as clean. In game, parents need an available fusion attempt and ingredients are consumed.
