How the optimizer chooses a build

The calculator enumerates every legal integer allocation for the selected objective, respects rank unlocks, applies the supported-build probability order, and ranks results by expected outcome. It does not use a generic tier list.

1. Enter progressionSet Mousey rank and whether the Darts jackpot doubles points.
2. Match modifiersEnable only the Zenith and Sushi bonuses active in the current run.
3. Choose a goalXP, Gold, and Shadow use different relevant skills and evidence levels.

Measured default example

Rank 35 XP preset

With 70 points, the Darts jackpot, the 4.5× Zenith chance multiplier, no Sushi bonus, and empirical Frictionless behavior:

Fire Darts: 31
Sparkie Chapter: 26
Mousey Synergy: 13

This is a crawlable reference preset, not a replacement for entering your own rank and modifiers above.

Best Mousey XP build

Balances Fire Darts experience per hit against Sparkie imbue chance, Gunner eligibility from Mousey Synergy, and the optional Frictionless throughput sensitivity.

Best Darts Gold build

Balances Golden Darts value, Alchemic global gold, magic chance, source weighting, and Gunner throughput. The source model remains experimental.

Best Shadow damage build

Uses fight duration to compare Arcane burst and Poison stacking while accounting for magic roll order and configurable player/Gunner sources.
