Biggest physical hit you survive: 6,989 → 9,319 counting 50% evade at half credit
13.6× a juiced T16 rare's hit (687) — the grader calls it safe from 16×
Path of Building's max hit assumes every hit lands. Avoidance stops most hits but not the unlucky one, so it counts at half.

Letter grade is a standard percentage scale: A ≥90, B ≥80, C ≥70, D ≥60, F below 60.

What the gear costs isn't part of the grade — it's priced separately below, so an excellent build is never marked down for being expensive. Full explanation of every score →

EHP already factors in Evasion (via hit-avoidance chance) and Armour, shown above as their own ratings for visibility. Armour's real mitigation is highly hit-size-dependent (PoE2's Armour / (Armour + 10 × Damage) formula) — strong against many small hits, weak against a single big one — so a high Armour rating alone doesn't mean as much survivability against pinnacle-boss-sized hits as it does against regular map packs. For that reason, the defense portion of Endgame/Farming-fit scoring on early_maps/mid_maps/high_maps now uses Max Physical Hit Taken (PoB's own "biggest hit that would exactly kill you," solved directly from your stats — not the ambiguous EHP figure) compared against a real reference monster hit at that tier, instead of the generic EHP bands. pinnacle_bosses still uses the generic EHP bands — no equivalent real per-boss hit-damage data exists to do the same for it.

Fire/Cold/Lightning Res above can look surprisingly low or negative even on a well-geared character. PoE2 applies a real, permanent -60% Elemental Resistance penalty by endgame (-10% per campaign Act, capping at Act 6) — Chaos Resistance is exempt. That means reaching the 75% display cap on Fire/Cold/Lightning takes 135% raw resistance from gear and the passive tree, not just 75%. A build showing e.g. 36% raw Cold Resistance will display as -24% here once that penalty is applied — that's this tool correctly reflecting a real, if widely-criticized, PoE2 mechanic, not a bug or a miscount of your gear.

Unique Items

Skills & DPS Combo

Pick which skill drives "DPS (main skill)" (single-target), and check any skills that should sum into "Full DPS" (PoB's combined-total feature — for totems, traps/mines, minion swarms, etc). For a totem/trap/mine/minion group, also pick which gem actually calculates damage — the other gem is the one you press (it triggers the payload automatically) and doesn't get its own DPS number. That same pick also decides how many "true buttons" the build counts as for Piloting Ease, below. Recalculates via the real engine.
