How scoring works

Every build gets a 0–100 score from four weighted components, then a letter grade. Here's exactly how each part is calculated.

The four components

Disc sets20%

We match your equipped 2pc/4pc bonuses against the build's ranked list of acceptable loadouts and score the best one you satisfy. Lower-priority loadouts take a small decay so any listed option stays viable.

Main stats25%

Slots 1–3 are fixed by the game (HP / ATK / DEF). Slots 4–6 are scored on whether their main stat is one the build wants — e.g. CRIT, element DMG, or ATK%.

Substats35%

Each disc's substat rolls are weighted by how much the build values them, then measured against an excellent, realistically achievable disc for that slot. A disc's main stat can never appear among its own substats, so the benchmark excludes it — a CRIT Rate–main disc isn't judged against CRIT Rate rolls it can't have. Exceptional discs reach S+, and a disc that meets or beats the benchmark tops out at GOD — though a disc wasting two or more of its lines is capped below the top. Rarity below S-rank scales the result down.

Stat goals20%

Your agent's final combat stats (agent + W-Engine + discs) are compared against the build's target thresholds, such as reaching a CRIT Rate / CRIT DMG breakpoint.

Weights are relative (20 / 25 / 35 / 20). If a build leaves a section undefined, that component is dropped and the rest are renormalized so the total always sums to 100%.

Letter grades

GOD

Score ≥ 98

S+

Score ≥ 87

Score ≥ 73

Score ≥ 58

Score ≥ 43

Score ≥ 31

Score < 31

The same thresholds grade both the overall build and each individual disc drive.

The fine print

Substat curve. Raw substat quality is raised to the power 0.8 so mid-range discs spread across B and A instead of piling up at the bottom — the benchmark is an excellent achievable disc, not a mathematically perfect one.
Main-stat exclusion. A disc's main stat is removed from its substat benchmark, since the game never rolls a stat as a substat on a disc that already has it as the main stat.
Wasted lines. Every disc carries 4 substat lines whether the build wants them or not. One dead line is the normal tax and never blocks a top grade; two dead lines cap a disc at 94, three or more at 84.
Rarity multiplier. A disc's substat score is scaled by its rarity — S-rank ×1, A-rank ×0.75, B-rank ×0.55.
Wrong main stat. A slot 4–6 disc with an off-build main stat keeps only ×0.3 of its substat score.
Loadout rank decay. Matching a lower-priority set combo costs 5% per rank, never dropping below ×0.85.
Disc level. Discs are expected to reach +15; under-levelled pieces are flagged since they haven't rolled all their substats yet.
