Comparison
Path of Building for Last EpochvsLast Epoch Tools
Two Last Epoch planners with opposing propositions. PoB-LE prioritizes simulation depth; LE Tools prioritizes visualization and community sharing. Serious theorycrafters use both.
Verdict
PoB for LE if you need exact DPS, item-vs-item comparison with computed delta, or to validate creator claims. LE Tools if you want a friendly UI, share via URL, or iterate visually fast. Theorycrafters use both: LE Tools to draft, PoB to validate before spending gold on crafting.

Which to use for what
- Exact DPS simulation with ailments and multipliersBetter pick: Path of Building for Last Epoch
PoB-LE simulates shock stacks, ignite stacking, DOT multipliers, conditional damage, and defense-layer order with real precision. LE Tools approximates these calculations.
- Share build via URL for Discord/RedditBetter pick: Last Epoch Tools
LE Tools generates a unique URL per build instantly. PoB uses "build codes" that are long strings less friendly to link in chat.
- Compare 2 items side-by-side with exact deltaBetter pick: Path of Building for Last Epoch
PoB-LE lets you equip item A, swap for item B, and see the delta on every stat. LE Tools requires manual comparison across tabs.
- Fast visual iteration during theorycraftBetter pick: Last Epoch Tools
LE Tools UI is friendlier: drag/drop gear, click-to-allocate passives, stats update visible. PoB inherits PoB PoE's complex UI with steep learning curve.
- Works offline / without internetBetter pick: Path of Building for Last Epoch
PoB-LE desktop runs 100% offline. LE Tools is web-only — without internet, you can't access your build or iterate.
LE has two main planners and the question "which do I use" depends entirely on what you're doing. PoB for Last Epoch and Last Epoch Tools' integrated planner solve different problems — they don't compete head-to-head.
Simulation depth vs visualization
PoB-LE (lastepochplanner.com or desktop) inherits the original Path of Building's calculation engine — the reference planner for ARPG theorycraft. For LE that means real-precision simulation:
- Shock stacks with all their multipliers.
- Ignite/bleed stacking with correct duration math.
- Conditional damage (vs full life, while channeling, on crit).
- Defense layers computed with the correct order of operations.
LE Tools planner approximates these calculations. For 90% of builds the approximation is sufficient — final numbers are close enough. For the 10% where the difference matters (ailment-stacking builds, conditional damage, ward defense optimization), PoB is the only honest option.
UI and learning curve
LE Tools planner is desktop-first but web-friendly, with clear self-explanatory UI. Drag/drop gear, click skills to open tree, stats visible. For newcomers, open and iterate in 2 minutes.
PoB-LE inherits PoB PoE layout — dense, with panels that assume you know the flow. For players never exposed to PoB, there's a real 30-60 minute curve before feeling productive. For players who already used PoB on PoE, it's instantly familiar.
Share and collaboration
LE Tools generates a unique URL per build. Paste into Discord/Reddit/forum and another user opens instantly. Ideal for community discussion.
PoB uses "build codes" — long strings (~500-1000 chars) you paste into chat. Works but less friendly. URLs win in discoverability and mobile.
Offline vs always-online
PoB-LE desktop runs 100% offline. If your internet goes down, you keep iterating builds.
LE Tools is web-only. Without internet, you can't access even your saved builds. For players with spotty connections or who travel, PoB desktop is a real advantage.
When each wins
| Use case | Winner | Why |
|---|---|---|
| Exact DPS simulation | PoB-LE | Engine inherits PoB PoE precision |
| Compare 2 items with delta | PoB-LE | Swap instantly and see per-stat delta |
| Share via URL in chat | LE Tools | Unique URL vs long build code |
| Fast visual iteration | LE Tools | Friendlier UI, drag/drop |
| Works offline | PoB-LE | Self-contained desktop binary |
| Newcomer to planners | LE Tools | Smooth learning curve |
| Validate creator claims | PoB-LE | Recompute their numbers from build code |
The combined recommendation
For intermediate/advanced players: LE Tools to draft + PoB to validate. You iterate visually in LE Tools because it's fast, then port the build to PoB when you need to validate numbers or decide to spend gold on crafting.
For newcomers: LE Tools is enough. PoB is overkill while you're still learning mechanics. When you reach endgame and start min-maxing specific items, that's when PoB starts paying off.
For pure theorycrafters: PoB first. The UI is worth the learning curve because precision is the only thing that matters in serious theorycraft.
