Timeless Jewel Calculator is a browser-based tool for Path of Exile that inspects any Timeless Jewel, searches all valid Seed numbers, and scores outcomes against an imported Path of Building (PoB) tree.
What is Timeless Jewel Calculator?
Timeless Jewel Calculator is a specialized web utility for Path of Exile players who need to analyze and optimize Timeless Jewels. It takes a jewel's item text as input, identifies its type, historical figure, and seed, then lets you search the entire seed range for a socket and score results against your chosen class and Ascendancy or an imported PoB tree. The tool runs entirely in the browser, keeps all inputs local, and adapts its full-tree renderer from the open-source project Vilsol/timeless-jewels under GPL-3.0.
Key Features
The tool provides a range of features that cover every step of jewel analysis, from pasting an item text to calculating the perfect seed.
- Jewel Inspector — Paste the item text from Path of Exile (Ctrl+V) and Timeless Jewel Calculator automatically identifies the jewel type, historical figure, and seed from 11 possible jewels such as Glorious Vanity (Vaal) or Lethal Pride (Karui).
- Private deterministic scoring — Calculations use a pinned PoB engine and run locally in your browser; no build data is uploaded or stored, and results are reproducible for a given seed.
- Reverse Seed Finder — Search every valid seed for the selected jewel/figure/socket, with up to three target outcomes (desired stat or node, each with a minimum weight), ranked by score. Results can be limited to the top 20, 50, or 100.
- PoB import — Import your build by pasting a PoB export code, raw XML, or a pobb.in URL; the tool decodes only the active passive tree, class, Ascendancy, and socketed Timeless Jewels, and then scores only allocated passives.
- Socket picker — Choose a socket from a searchable list of 15 all-tree sockets (with region and node ID) or visually select on the rendered passive tree.
- Share and export — Create shareable links that open the exact jewel and recalculate locally, or generate card images for Reddit, Discord, and ShareX.
- Field guide — A built-in guide explains socket, seed, and transformation mechanics without leaving the calculator workflow.
Who is it for?
Timeless Jewel Calculator is made for Path of Exile players who own or want to use Timeless Jewels, from casual players to hardcore optimizers. It is especially useful for those who use Path of Building to plan their allocations.
- Endgame players — Find the best seed number to achieve a specific keystone or notable in an existing build.
- Build theorycrafters — Maintain PoB trees that use Timeless Jewels and need to find the optimal seed to maximize allocated passives.
- Trade-savvy players — Evaluate a jewel’s seed value before buying or selling, or identify which sockets on their build could benefit from a new jewel.
What can you do with Timeless Jewel Calculator?
This web tool gives you a full workflow for working with any Timeless Jewel, whether you are identifying, comparing, or planning your passive tree.
- Identify any jewel — Paste a jewel’s item text to instantly see its type, historical figure, and seed, then check how it affects the tree from any socket.
- Optimize your passive tree — Import your PoB build, select a Timeless Jewel socket, and search the seed range for the wheel that grants the most valuable passives for your class and Ascendancy.
- Compare multiple outcomes — Set up to three target nodes or stats, each with a minimum weight, and have the tool rank seeds by how well they match those outcomes.
- Share and analyze jewels — Generate a shareable link for a specific jewel and socket, allowing others to recalculate the results locally without an account or any uploaded data.
How does Timeless Jewel Calculator work?
The workflow is straightforward: paste (or type) the jewel's item text to auto-detect its type, figure, and seed; choose your character class and Ascendancy; select the jewel socket on the tree or from the sorted list; optionally import a PoB build; and then run a reverse seed search with up to three target outcomes. The tool iterates over the entire seed range using its local worker, then displays a ranked score table with matches and actions. All computation stays on your device, and the results never leave the browser.
Pricing
Timeless Jewel Calculator is free to use, with no account or paid plan required. The web page does not mention any subscription, premium tier, or transaction-based features.
FAQ
Is Timeless Jewel Calculator free?
Yes, the calculator is free to use. The website does not require an account and does not mention any paid or premium plan.
Does Timeless Jewel Calculator upload my data?
No. All calculations run locally in your browser. When you paste item text or import a PoB code, the active tree is decoded locally and never uploaded to a server. The shareable links also recalculate on the viewer’s own browser.
How do I import my Path of Building tree?
Copy your PoB export code (or raw XML, or a pobb.in URL) and paste it in the import dialog. The tool reads only the active passive tree, class, Ascendancy, and socketed Timeless Jewels, then lets you score only allocated passives.
Which Timeless Jewels are supported?
The calculator covers all 11 league-based Timeless Jewels, including Glorious Vanity, Lethal Pride, Brutal Restraint, Militant Faith, Elegant Hubris, Heroic Tragedy, and the five more recent expansion jewels (Festering Vengeance, Extinguishing Grasp, Baleful Dominion, Destructive Aspiration, Reclaimed Malevolence). Each requires selecting the correct historical figure and falls within its own seed range.
