Item Search Regex Builder
Your waystone search regex
Paste into the search box with Ctrl+F. Matching waystones light up; the rest dim.
How this works
Path of Exile 2’s search boxes accept a regular expression and highlight any item whose text contains a match. The search is case-insensitive and checks each line of the item, so you rarely need real regex syntax — a plain word is already a search, and | means “or”. The catch is the 50-character limit (GGG has said it will rise to 250), so long mod names don’t fit.
This builder solves that by picking, for each modifier you tick, the shortest fragment of its real in-game text that no other waystone modifier shares — so “increased Critical Hit Chance” becomes just bonus (from its “Critical Damage Bonus” line), because shorter words like “critical” also appear on the “reduced Extra Damage from Critical Hits” mod. Every fragment is drawn from letters only, so it keeps working no matter what number the mod rolls, and it’s checked against every other modifier in the pool so it won’t light up mods you didn’t ask for.
The same string works whether you want to find good mods (keep the ones that light up) or avoid bad ones (reroll or skip the ones that light up).
Some modifiers cannot be isolated at all, and the builder says so rather than pretending otherwise. It happens whenever a modifier’s whole text sits inside a longer one’s: any search for “#% increased Movement Speed” necessarily also catches “#% increased Movement Speed if you haven’t been Hit Recently”. That is a property of the game’s text, not of this tool — no search string can separate them — so the result panel lists exactly what else will light up. It is rare on waystones and tablets, and common on gear, where affixes are routinely extended with an extra condition.
Every search is a link. The address bar updates as you tick, so you can paste your setup into a party chat or a guide and whoever opens it sees the same picks — use Copy share link in the result panel.
The full modifier pools live on the Waystones, Tablets, Modifiers and Relics pages, with every tier and roll range; the league mechanics reference explains what each map layer does.
PoE2 regex FAQ
- How do I use a regex in Path of Exile 2?
- Open the window you want to search — your waystone stash, tablet stash, a normal stash tab or a vendor — and press Ctrl-F (or click the search box). Paste the string this tool gives you. Every item whose text contains a match lights up and the rest dim, so you can instantly spot the waystones or tablets carrying the mods you picked.
- Why is the generated regex so short and cryptic?
- The in-game search box has a 50-character limit today, so full mod names rarely fit. Instead of the whole line, the builder uses the shortest fragment of the modifier's real text that no other modifier in the pool shares — often a single distinctive word. It reads oddly on its own, but it highlights exactly the mods you ticked and nothing else, while staying under the limit.
- Can I search for dangerous map mods to avoid?
- Yes — that's the most common use. Tick the modifiers you don't want to run (for example ones that reduce your maximum resistances, cut your recovery, or add extra elemental damage), and the regex highlights any waystone carrying them so you can reroll or skip it. The exact same string works the other way round if you'd rather highlight the mods you want to keep.
- Does the search match the rolled numbers on a mod?
- It can, but this builder deliberately doesn't rely on them. Every fragment it generates is made of letters only, so it keeps working whatever value the modifier rolls on a given waystone tier. That means one search string stays correct across every tier of waystone and tablet.
- Why does it say my search also highlights other mods?
- Because some modifiers genuinely cannot be told apart by text. It happens when one modifier's whole line sits inside a longer one — a search for 'increased Movement Speed' must also catch 'increased Movement Speed if you haven't been Hit Recently', and a plain 'increased Quantity of Waystones found' tablet shares its only line with several tablets that carry it as a bonus. No search string can separate them, so instead of hiding it the builder lists exactly which extras will light up. It's rare on waystones and tablets and common on gear, where affixes are routinely extended with an extra condition.
- Can I search my stash for gear affixes, not just map mods?
- Yes. Switch to the Gear tab for the full item modifier pool, or Jewel, Flask & charm and Relic for those windows. Gear is a large pool, so use the filter box to find a modifier by its text and the item-class dropdown to narrow to the slot you're rolling — a modifier with no class restriction always stays in the list, because it can appear anywhere. Whatever you tick, the search string is built against the whole pool, so it stays accurate in a stash tab holding every kind of item.
- Can I share a search I've built?
- Yes — the page address updates as you tick modifiers, so copying the URL out of the address bar (or using 'Copy share link' in the result panel) gives a link that opens with exactly your picks selected. The link stores the modifiers themselves rather than their positions in the list, so it keeps working after a game patch adds or reorders modifiers; anything genuinely removed by a patch is quietly dropped rather than shifting your other picks.
- Is the search case-sensitive?
- No. Path of Exile 2's item search is case-insensitive and matches each line of the item text, so you never have to worry about capitalisation. This tool outputs everything in lower case for that reason.
