Quick answer: A Reliquary Key in Path of Exile 2 unlocks the Reliquary Vault — a special Atlas map that holds a chest guaranteed to drop a foiled (foil/shiny) Unique item. The common Twilight Reliquary Key is a rare global drop (item level 65) that gives a random non-boss-exclusive foiled unique — a cheap lottery ticket. Boss-specific keys (Xesht's, Zarokh's, The Trialmaster's, Olroth's, and more) drop from their matching pinnacle boss and let you target a specific chase unique as a foil — e.g. Zarokh's key drops Temporalis, Xesht's key drops Hand of Wisdom and Action. Boss keys are where the real money is: you either kill the pinnacle boss yourself or buy the key, then cash in the foiled unique.
If you've picked up a Twilight Reliquary Key off a random rare and had no idea what to do with it — you're not alone. This is one of the least-explained systems in the 0.5 "Return of the Ancients" endgame, and the confusion is made worse because "Reliquary" also refers to a supporter-pack nomination feature that has nothing to do with the key in your stash. This guide clears it up: what the vault actually is, exactly how to open it, every boss-specific key and the foiled unique it targets, and — most importantly — which keys are worth farming or buying and which are junk. Everything here is verified against poe2db, the PoE2 Wiki, and Game8 for the current 0.5.4 patch.

What Is a Reliquary Key and the Reliquary Vault?
A Reliquary Key is a consumable Atlas item. You slot it into the Map Device (the same device you use to run Waystones), and it opens a one-off area called The Reliquary Vault. Inside is a golden relic chest — the Twilight Order Chest — that drops a foiled Unique item.
"Foiled" is a cosmetic foil (shiny) treatment on an otherwise normal Unique. Per the PoE2 Wiki, a Reliquary Key "grants access to the Reliquary Vault via the Atlas, which drops a foil version of uniques selected by players who have purchased the Liberator of Wraeclast Supporter Pack." That's the key thing to understand: the pool of uniques you can pull is the set that founder-pack owners nominated — so it's a curated slice of the game's uniques, dressed up in a collector-grade foil.
The foil is purely visual — the item's mods are identical to the base unique. A foiled Temporalis rolls the same stats as a normal Temporalis; it just looks fancier and carries collector value. So the reason to chase these isn't power — it's the guaranteed unique drop and the foil premium.
This is a separate system from the "Reliquary Nomination" in the Liberator of Wraeclast supporter pack (which is a website feature where supporters pick which unique goes into the pool). Players constantly conflate the two. The key in your inventory is the endgame drop; the nomination is the founder feature that stocked the pool. If you're farming, only the key matters.
Twilight Reliquary Keys vs. Boss-Specific Keys
There are two classes of Reliquary Key, and the difference is everything:
| Twilight Reliquary Key | Boss-Specific (Pinnacle) Key | |
|---|---|---|
| Drops from | Any endgame monster (global drop, item level 65) | Its matching pinnacle boss only |
| Vault reward | Random non-boss-exclusive foiled unique | That boss's exclusive foiled unique |
| Targeting | None — pure lottery | Precise — one specific chase item |
| Rarity / value | Common, cheap | Rare, valuable |
The Twilight Reliquary Key is a global drop — it can fall from any monster once you're in maps, and it opens the vault for a random unique from the global (non-boss-locked) pool. Boss-exclusive chase uniques like Temporalis or Hand of Wisdom and Action will never appear from a Twilight key. That's why Twilight keys are cheap: most of the time you pull a low-value unique, so they trade like a scratch card.
Boss-specific keys are the opposite. Each pinnacle boss has its own Reliquary Key that drops when you kill it, and that key's vault contains that boss's exclusive foiled unique. This turns the vault into a deterministic target farm: instead of grinding the boss over and over hoping the raw unique drops, the key guarantees the item (in foil) when you open the vault.
How Do You Open the Reliquary Vault?
It takes about 20 seconds once you have a key:
- Get a key — pick up a Twilight Reliquary Key from any endgame drop, or a boss-specific key from a pinnacle kill (or buy one via trade).
- Go to your Atlas / Map Device. The Reliquary Vault sits as a node on the Atlas near your starting area — look for the relic/home icon on the Atlas map.
- Insert the key into the Map Device the same way you'd load a Waystone, then open the portal.
- Enter the vault and open the chest (the Twilight Order Chest). It drops your guaranteed foiled unique.
That's it — there's no additional currency cost to open the vault beyond the key itself. One key = one vault run = one guaranteed foiled unique. As the in-game Twilight Reliquary Key item text spells out: "Travel to the Reliquary Vault by using this key from a Map Device. Can only be used once." — so don't expect to reuse a key after a run.
Every Boss-Specific Reliquary Key (and What It Targets)
The current 0.5 endgame has a Reliquary Key for essentially every pinnacle boss. These are the ones you'll actually see traded and farmed:
| Reliquary Key | Source Boss | Content | Notable Foiled Target |
|---|---|---|---|
| Xesht's Reliquary Key | Xesht, We That Are One | Breach pinnacle | Hand of Wisdom and Action |
| Zarokh's Reliquary Key | Zarokh, the Temporal | Trial of the Sekhemas (floor 4) | Temporalis (Silk Robe) |
| The Trialmaster's Reliquary Key | The Trialmaster | Trial of Chaos | Trialmaster-exclusive uniques |
| The Arbiter's Reliquary Key | The Arbiter of Ash | Pinnacle | Arbiter-exclusive uniques |
| Olroth's Reliquary Key | Olroth, Origin of the Fall | Expedition pinnacle | Olroth-exclusive uniques |
| Ritualistic Reliquary Key | Ritual pinnacle line | Ritual | Ritual-exclusive uniques |
| Tangmazu's Reliquary Key | Tangmazu | Delirium | Delirium-exclusive uniques |
Other keys also exist for pinnacle and Simulacrum-tier encounters (Kosis the Revelation, Omniphobia, The Arbiter of Divinity, The Aberration, and more), but they trade far less often. Note: the game's database still lists some legacy PoE1-style reliquary keys that are not obtainable in 0.5 — if you can't find a key on the trade site or in a current boss loot table, treat it as not farmable.
Two flagship examples show why boss keys matter. Temporalis is exclusive to Zarokh, the Temporal — the raw item only drops if you clear all four Sekhemas floors and, on a Last Flame–influenced run, take zero damage to guarantee it. Zarokh's Reliquary Key sidesteps that entirely: the vault hands you a foiled Temporalis. Likewise, Hand of Wisdom and Action is locked to the Breach pinnacle Xesht — its Reliquary Key is the clean way to target it.

Which Reliquary Keys Are Actually Worth Farming?
Here's the honest value read for 0.5.4:
- Twilight Reliquary Keys — low value, but free money. They cost almost nothing to buy and drop passively while you map. Never farm them on purpose, but always open (or sell) the ones you find. Treat a stack as a cheap gamble, not income.
- Cheap boss keys (Tangmazu's, Ritualistic) — situational. Worth it only if their target foiled unique is in demand that league. Price-check before you invest boss kills into them.
- Premium boss keys (The Trialmaster's, Zarokh's, Xesht's) — the real prize. These target the game's chase uniques, so both the key and the resulting foiled unique carry serious value. The Trialmaster's key is consistently one of the most expensive keys traded. If you can reliably kill these pinnacle bosses, their Reliquary Keys are a direct currency printer.
The core takeaway: the money in the Reliquary system isn't the vault — it's your ability to kill the pinnacle boss that drops the key. Every boss key is really a receipt for a pinnacle clear. If a boss wall is blocking you from farming its key (or its base unique), a boss carry / pinnacle service gets you the kill and the key without the gear check.

How to Farm Reliquary Keys Fast
For Twilight keys: just map. They're a global drop, so juiced T15+ maps with high monster density and increased quantity/rarity are the fastest passive source — the same juicing you'd already do for currency. Don't build around them.
For boss keys: farm the pinnacle boss directly.
- Xesht's key → run Breach farming to the Xesht pinnacle.
- Zarokh's key → grind Trial of the Sekhemas to the floor-4 boss.
- The Trialmaster's key → farm the Trial of Chaos / Trialmaster.
- Olroth's key → push Expedition to its pinnacle.
- Ritualistic key → run the Ritual / King in the Mists line.
Because the foil is cosmetic, always price-check both the key and the foiled unique on poe.ninja / poe2scout before committing — foil premiums swing hard through a league. When a chase item's foil is spiking, farming that boss's key is one of the better raw-currency-per-hour plays in the endgame.
Frequently Asked Questions
How do you get a Reliquary Key in PoE2? Twilight Reliquary Keys are a rare global drop from any endgame monster once you reach the Atlas (item level 65). Boss-specific keys drop only from their matching pinnacle boss when you kill it. All Reliquary Keys are tradeable, so you can also buy them from other players.
How do you open the Reliquary Vault? Insert the Reliquary Key into your Map Device (like a Waystone), then open the portal to the Reliquary Vault — a node on the Atlas near your starting area (look for the relic/home icon). Inside, open the golden Twilight Order Chest for a guaranteed foiled unique. There's no extra currency cost beyond the key.
Are Twilight Reliquary Keys worth it? They're cheap for a reason — the vault gives a random non-boss-exclusive unique, so most opens are low value. Always open or sell the ones you find (free value), but don't farm them on purpose. Chase uniques like Temporalis will never come from a Twilight key.
What's the difference between Twilight and boss-specific Reliquary Keys? A Twilight key gives a random unique from the global pool. A boss-specific key (e.g. Zarokh's, Xesht's) targets that boss's exclusive foiled unique — so it's a deterministic way to get a specific chase item instead of gambling.
Do foiled uniques have different stats? No. The foil is a cosmetic-only treatment — a foiled unique rolls the exact same modifiers as the normal version. You farm them for the guaranteed drop and the collector/foil value, not for extra power.
Can you buy Reliquary Keys instead of farming bosses? Yes — every current Reliquary Key is tradeable. If a pinnacle boss is a wall for you, buying the key (or the foiled unique directly) is often cheaper in time than repeatedly attempting the fight; a boss carry is the third option for getting the kill and the key on your own account.
