What is Epoch DPS?

Epoch DPS is a free, per-skill damage calculator for Last Epoch. Paste a lastepochtools planner link and it breaks the build down skill by skill, showing what each one does against a target rather than a single sheet number.

Sheet DPS is the naive hit-times-attack-speed-times-crit figure. Effective DPS accounts for what actually lands over time: ailment stacks, damage-over-time, minions, transforms, echoes, hit chance, and the target's defences. For most builds the two are a long way apart, and the gap is usually where the build lives.

This is an alpha. The numbers are estimates meant for comparing builds and finding what scales, not exact in-game readouts. Expect rough edges, and check the assumptions panel for anything the engine hasn't modelled yet.

How it works

  1. Paste a planner link

    Drop in a lastepochtools planner link (or just the code). Epoch DPS pulls the build straight from lastepochtools' public planner API.

  2. Read the per-skill breakdown

    Every skill, sub-skill, and ailment gets its own effective DPS and a full stat breakdown, so you can see exactly what carries the build.

  3. Tune and share

    Adjust the assumptions — target, ailment stacks, roll mode, conditional buffs — then share the /b/ link so anyone can open the same result.

FAQ

How accurate are the numbers?

It's an alpha. The engine aims to land within a few percent of what lastepochtools' own offence tab reports for global stats, but per-skill effective DPS is a model, not a measurement. Treat every figure as an estimate for comparing builds and finding what scales — not a guaranteed in-game readout.

Why are my numbers higher than lastepochtools?

By default Epoch DPS rolls every affix and implicit to its maximum — the build ceiling — so it usually sits above lastepochtools, which shows the average of each roll range for planner builds. Switch the roll mode to Average to compare like for like.

What does it actually model?

Direct skills, sub-skills (cast-on-hit and procs), ailments and damage-over-time, minions and their own skills, player transforms such as Werebear and Swarmblade, and echo repeats. Scaling from stats, tags, tree nodes, idols, affixes, uniques, and conditional buffs is folded into each skill's breakdown. Some mechanics still aren't modelled — those are flagged in the assumptions panel.

How does sharing work?

Every analysed build gets a stable link at /b/<code>, where the code is the lastepochtools planner code. Send that link and whoever opens it sees the same per-skill breakdown. No account needed.

Is it free?

Yes — free, no ads, no account, no paywall. It's a community tool built by a Last Epoch player for other players.

Is this affiliated with Last Epoch or lastepochtools?

No. Epoch DPS is an independent, unofficial tool. It is not affiliated with, endorsed by, or connected to Eleventh Hour Games (the makers of Last Epoch) or lastepochtools.com. Build data is fetched from lastepochtools' public planner API; all trademarks belong to their respective owners.

Changelog
July 21, 2026
  • changelog date sections are now collapsible — the newest date stays open, older dates start collapsed
  • modifiers with two conditions now keep BOTH (e.g. Nightbringer's 'hit damage to Blinded Enemies with Multishot') — previously the second condition was dropped; both must now be satisfied and their stack scaling combines
  • added Lethal Concentration logic — 'N% of Player Poison Damage Applies to Skeleton Rogues / your Falcon' now feeds the player's typed added and increased damage onto the named minion
  • added '+X Damage Over Time' logic — flat added damage-over-time now boosts every matching-type DoT ailment the build inflicts (e.g. The Ghost Maker)
  • Omen of Thunder's '+Spell Lightning Damage for all existing totems' is now counted — the 'all existing' wording was previously dropped
  • corrected Crystalwind, Unearthed Memories, and Lament unique text against lastepochtools — added Crystalwind's bow scope, Unearthed's 'against cursed enemies' restriction, and Lament's missing Spell Void Damage line
  • corrected Spark Charge damage — now uses the explosion's base (20 lightning, 100% added-damage effectiveness) and its +4% damage per Intelligence, fixing a large under-count on Spark Charge builds (in-game validated within 3%)
  • changelog now groups changes under a date header instead of repeating the date on every line
  • fixed Hand of Judgement's '+X Melee Damage per Attunement for Judgement' — now scales by Attunement and applies only to Judgement (was a flat bonus applied to every skill)
  • corrected 'while Unarmed' detection — now requires no weapon in either hand (a Shield or Off-Hand Catalyst still counts as unarmed, and an off-hand weapon now correctly counts as armed), fixing Hand of Judgement and similar unarmed-gated mods
  • fixed dropped skill-scoped flat damage on uniques/idols — mods like '+52 Melee Damage for Shield Bash' and '+18 Spell Damage for Storm Bolt' are now counted for that skill instead of being ignored
  • fixed Fragment of the Enigma's Spark Charge modifier — now applied as a multiplicative 'more' scoped to melee appliers (was counted as additive 'increased' and applied to all appliers), matching the in-game tooltip
  • corrected Shield Throw ricochet model (in-game validated): count the return-to-you bounce toward Lava Burst procs, and only count single-target return hits — fixes a ~35% DPS under-prediction on ricochet builds
  • new engraved masthead + typographic refresh
  • replaced emoji icons with custom sigils
  • class-colored build identity + timeline divider
  • added a DPS composition bar
  • fixed dropped damage/ailment conversions on tree nodes that also carry a structured stat (e.g. Upheaval's Glacial Cascade phys->cold)
July 19, 2026

  • transform rotation now honors attack speed
  • fixed Wildfire Embers fire penetration over-count
