Nami Item Calculator — Build Compare

One box per ability comparing Build A vs Build B. Bars are totals, stacked by source.

Overall Showdown — A vs B

What goes into each row

Slow / MS: Average of two percent-increases: Tidecaller's slow (rank base + 0.05×AP) and Surging Tides passive move speed (100 + 0.25×AP). Both scale with AP only — Nami's own boots / move speed do not count.
Trade damage: Average total damage of the two 2v2 trade combos (W damage-focused + W heal-focused), each with 3 Tidecaller procs and Aery.
Trade heal/shield: Average of (heal + shield) totals from those same two 2v2 combos. Includes Helia at full cap, Moonstone chains, and Aery shield.
Burst damage: Total damage of the solo single-target burst: R → W → 3 Tidecaller procs → Q, plus Aery. Mandate's Vulnerable applies after R; Staff Rapids counts.
Sustained DPS: The damage rows of the Sustained output / second card, summed: W·Damage/s + E·Damage/s. Per second on effective cooldowns (reduced by Ability Haste); W is modeled as the 2v2 ally-first cast.
DPS heal/shield: The heal + shield rows of that same card, summed: W·Heal/s (base + AP + Helia + Moonstone chain) + Aery·Shield/s (+ Moonstone chain). Per second on effective cooldowns.
Gold cost: Total gold spent on each build. The bar fills toward the more expensive build; the number is the raw gold difference between the two (not a percent).

Each bar's % = how much more the leading build does than the other ((leader − loser) ÷ loser) — except Gold cost, whose number is the flat gold gap. Slow / MS shows the averaged percent of its two parts.
