The Atlas, Waystones, and core currency

Why this lesson matters

Once you finish the campaign, POE2's endgame loop runs through the Atlas — a web of maps you access via Waystones, shaped by Tablets you apply directly to your maps, and layered underneath a whole separate progression system most intro guides skip. Currency is the other half: the orbs that modify your gear, several of which work differently from what Path of Exile 1 veterans expect.

Waystones: T1-T15 drop naturally, T16 doesn't

The Map Device (at the Ziggurat Refuge) is where you insert a Waystone to open portals to that map. One recent wrinkle: as of patch 0.5.0, Waystones must be identified before they'll work in the Map Device — an unidentified one won't activate.

Waystones range from T1 to T15 as natural drops. T16 is the current effective ceiling, and it never drops naturally — the only way to get one is corrupting a T15 Waystone with a Vaal Orb, a low-odds gamble rather than something you can farm directly. If you've seen older content mentioning T17-T19 "virtual tiers," treat that as unconfirmed for the current patch — it traces to older sources that predate the 0.5.0 Atlas overhaul, and nothing current corroborates it.

Precursor Tablets go into the Map Device — Towers are just maps now

Worth being precise here, since this genuinely changed and a lot of guides never caught up: as of patch 0.3.1 (October 2025), Towers and Tablets are completely decoupled. GGG's own patch notes say it directly: "You no longer need Towers to use Precursor Tablets, instead, Tablets can now be placed into the Map Device to add their bonuses directly to your Map." Nothing since — including the big 0.5.0 Atlas overhaul — reversed this.

So the current mechanic is: you apply Tablets directly to the map you're about to run, through the Map Device, alongside your Waystone. 3 Tablets is the base cap, and how many of those slots you can actually use is gated by that map's own modifier count — GGG's notes: a Waystone with 6 modifiers unlocks all 3 slots. Tablets can't be applied to a map you've already attempted, so decide before you go in.

A 4th tablet slot exists as an endgame exception, not a replacement for that rule: allocate the Atlas notable Industrial Improvements ("An additional Tablet may be used on City Maps") and run a City-biome map (area level 75+). Without both, you stay at 3.

Towers themselves are now just regular maps you run like any other — clearing one reveals fog of war on the surrounding Atlas and hands you a bonus Tablet as a completion reward. That's it. A Tower is no longer a persistent node with a coverage radius, and it no longer buffs nearby maps just by having a Tablet sitting in it.

To plan tablets (and Instill) on a specific farm — including the 4th socket when Industrial Improvements and a City layout are set — use Farming strategies.

The old "stack overlapping Towers" strategy doesn't exist anymore

If you've read a guide describing Tower radii overlapping and stacking their effects for compounding bonuses — that's describing the pre-0.3.1 system, not the current one. Some guide sites kept their pages up with recent-looking "last updated" dates without actually rewriting the mechanic description, so this misinformation is still floating around. The current equivalent of "juicing" a map isn't overlapping Towers — it's stacking Tablets (3 on a 6-mod Waystone; 4 on a City map with Industrial Improvements) plus a good Waystone's own modifiers onto a single map via the Map Device.

The Atlas Passive Tree is a whole progression layer most quick guides skip

The Map Device/Waystone/Tablet/Tower loop is the mechanical *input* system — how you access and juice maps. But it sits inside a much bigger progression layer that governs what that loop actually unlocks, and it's easy to miss if you're only looking at the map-running part of the game.

Since patch 0.5.0 ("Return of the Ancients"), the Atlas Passive Tree was massively expanded — estimates range from roughly 200 to 300+ nodes, in a dedicated Atlas Tree UI separate from your character's passive tree. It grants drop-rate bonuses, mechanic frequency, and boss access. Each major league mechanic (Breach, Delirium, Abyss, Expedition, Ritual, and others) is now gated behind its own questline that unlocks both the content and Atlas passive points for it, rather than being open from the start. A separate Atlas Masters system — three Masters, each with their own sub-tree — adds further customization, and 15 Atlas Pinnacle Bosses are reached through these mechanic-specific questlines.

If your endgame planning is only "run maps, place tablets," you're missing a real lever — a lot of your power growth in maps comes from this tree, not just gear upgrades. Browse and allocate it on the Atlas tree.

Currency: what actually exists, and one that doesn't

Trade and crafting run on orb currency. Here's the current, verified list:

• Orb of Transmutation — Normal → Magic, adds 1 random modifier.
• Orb of Augmentation — adds a 2nd modifier to a Magic item that only has one.
• Orb of Alchemy — Normal straight to Rare, 4 random modifiers, skipping Magic entirely.
• Regal Orb — Magic → Rare, keeps existing modifiers, adds one new one. (The jump to a 6-modifier cap comes from becoming Rare-rarity, not from something the orb itself "expands.")
• Chaos Orb — removes one random modifier from a Rare item and adds one new one. This is not a full reroll, unlike Path of Exile 1's Chaos Orb — a targeted swap, not a reset button. Some stale guides still describe the old PoE1 behavior; don't trust them. Greater and Perfect Chaos Orbs do the same one-in/one-out swap, but force the replacement modifier into a higher level band — same mechanic, not a different orb.
• Exalted Orb — adds a new modifier to a Rare item that hasn't hit its 6-modifier cap, without touching what's already there.
• Orb of Annulment — removes a random modifier with no replacement, the inverse of Exalted.
• Vaal Orb — corrupts an item for a random outcome (good or ruinous), unmodifiable by ordinary currency afterward. (One narrow exception as of 0.5.4: Orb of Sacrifice can modify certain corrupted items in specific ways — a specialized tool, not a core currency.)
• Divine Orb — rerolls the numeric values of existing modifiers within their ranges, doesn't change which modifiers are present.
• Orb of Chance — unpredictably upgrades a Normal item to Unique, or destroys it.
• Mirror of Kalandra — copies another non-Unique item exactly. The rarest currency in the game by a wide margin.

"Orb of Alteration" does not exist in current POE2. If you're carrying Path of Exile 1 knowledge, this is a real trap — it's a genuine PoE1 currency name, and it doesn't correspond to anything in POE2's current item list. Whatever role you're expecting it to fill (rerolling a Magic item's modifier), Orb of Augmentation and Orb of Alchemy are the actual current tools for shaping a Magic-tier item.

Live prices for these orbs are on Economy.

Practical tips

• Apply Tablets to the specific map you're about to run via the Map Device — not to a Tower, and not as a standing radius buff. Plan ahead, since you can't apply one to a map you've already attempted. Base cap is 3 (6-mod Waystone unlocks all three); a 4th needs Industrial Improvements plus a City map.
• Don't build a farming route around "staying inside a Tower's coverage" — that behavior doesn't exist anymore. Run Towers for their guaranteed Tablet drop and the Atlas reveal, same as you'd run any other map.
• Be skeptical of guides describing Tower radius-stacking as a current strategy — that's very likely stale content describing the pre-October-2025 system, even if the page looks recently updated.
• Check the Atlas Passive Tree and Masters early — a meaningful chunk of your endgame power comes from there, not just from running more maps.
• If you're hunting for "Orb of Alteration," stop — it's not in this game. Augmentation and Alchemy cover that ground instead.
• Save Exalted Orbs and other high-value currency for items with high enough item level to roll strong modifiers — spending them on a low-iLvl base wastes their potential.
