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.
