What it is
tarnished.dev is a modern build planner maintained by an independent dev. It lives at tarnished.dev/build-planner and covers the base game + Shadow of the Erdtree. Free, no ads, no login. Data is updated with each major balance patch (typically within 1-2 weeks of release).
The UI is built with UX in mind: item cards, optional drag-and-drop for swaps, collapsible panels. Each build generates a shareable URL that preserves all state.
What it solves
Classic planners (Mugen Monkey, EIP) are functional but item-lookup friction is high — long dropdowns, infinite scrolls. tarnished.dev solves this with fuzzy search: type "blood" and Bloodhound's Fang, Mohgwyn's Sacred Spear, Bloody Helice, etc. appear.
It also solves build-sharing: the URL is stable, copy-paste to Discord or Reddit works, and anyone opens it without installing anything.
Differentiation
Against EIP it wins on UX (fuzzy search, smooth animations) and iteration speed. It loses on rare-item coverage — some DLC items took time to appear post-launch, though as of 2026 it's complete. Against Mugen Monkey, it wins on everything visual but loses on starting class optimizer (Mugen's unique feature).
What people use it for
Fast iteration: try 5 variants of a build in 10 minutes without wrestling with dropdowns.
Builds shared on Discord: the URL is the standard way to pass a build to a friend.
Visual validation: see your Tarnished with full gear, talismans visible, on a single screen.
DLC planning: with Scadutree Fragments integrated, you plan your effective Realm of Shadow level.
Mobile-friendly: responsive works, you can edit builds from your phone.
Who shouldn't use it
If your priority is minimum-total-level optimization (capped PvP), Mugen Monkey does it better with its class optimizer.
If you want 100% complete data on obscure items, EIP usually has better longtail coverage.
If JS-heavy sites bother you, the cold start of tarnished.dev is slow — ~2 seconds to render initial UI.
How it's used in practice
- Open
tarnished.dev/build-planner. - Pick starting class from the top dropdown.
- Raise stats with sliders or type the value.
- To equip items, click an empty slot → search bar → type the first letters of the name.
- Repeat for all slots (weapons, armor, talismans, sorceries, incantations).
- Check AR/defenses in the side panel.
- Copy the URL — the full build is encoded in the path.
Honest limitations
Slow cold start: the JS bundle is heavy, first load is slower than Mugen.
No starting class optimizer: you must test manually or consult Mugen.
No frame data: for frame-perfect counter-play or i-frames on rolls/dodges, consult Emilia's Frame Data Explorer.
Maintained by one person: update cadence is good but may pause if the dev is busy.
No JSON export: the URL is the only export format.
How to start
- Visit
tarnished.dev/build-planner. - Pick starting class.
- Define target level (NG cap or PvP 125/150).
- Iterate stats and gear until you hit the desired spread.
- Copy the final URL and save it.
