If your maps in Path of Exile 2 feel empty — thin loot, no encounters, barely any currency — the fix almost always comes down to two systems most players underuse: Precursor Tablets and Lost Towers. In the Runes of Aldur league (patch 0.5 "Return of the Ancients"), tablets are the single biggest lever you have for turning a plain map into a currency engine: they bolt Breach, Expedition, Delirium and bosses onto whole regions of your Atlas at once, and their effects stack.
The catch is that the game barely explains them. You loot a tablet, the tooltip says it goes in a "completed Tower," and that's about it — so most exiles either hoard them or throw them away. This guide is the full system, end to end: where tablets drop, how to clear a Tower and slot them, what every tablet type does, how the stacking actually works, and the exact way top currency farmers chain Towers to print Divine and Exalted Orbs. Every mechanic here is checked against the official PoE2 patch notes and wiki — not a stale tracker.
PoE2 tablets & towers in 30 seconds (the quick answer)
- What a tablet is: a Precursor Tablet is a currency artifact that drops from enemies in maps. Slot it into a Tower and it adds modifiers to every map in that Tower's radius on your Atlas.
- How you use one: you can't use a tablet from your inventory. You first clear a Lost Tower map, activate the Precursor Beacon at the end, then place tablets into it from the Atlas screen. Each Tower holds up to 3 tablets.
- What they do: add map-wide juice (item rarity, pack size, more rares) or bolt on an Activity — Breach, Expedition, Delirium, Ritual, Abyss — or add Map Bosses (the Overseer tablet).
- The key rule: tablet effects stack. Overlap two or three Towers over the same maps and you run multiple mechanics on one juiced map.
- The hard numbers: every tablet carries 10 charges, a Tower has up to 3 slots, and a rare (3-mod) tablet can sell for 30+ Exalted Orbs on trade.
- The payoff: juiced maps drop far more raw currency, Activity loot, and high-tier Waystones — the difference between scraping by and farming Divine Orbs per hour.
- The #1 mistake: hoarding tablets "for later." Maxroll's advice is blunt — "Do not be afraid to use tablets on your maps... the more you use the more tablets you get back." Slot them and run.
What are Precursor Tablets in PoE2?
A Precursor Tablet is, in IGN's words, one of the "mysterious, archaic artifacts you'll find during the endgame of Path of Exile 2" that "can add powerful modifiers to the maps you explore in the Atlas of Worlds." Think of them as regional map juice: instead of rolling one Waystone for one map, a tablet boosts a whole cluster of maps around a Tower at once.
Tablets drop straight from monsters while you map — any enemy can drop one, and like other items they come as normal, magic, or rare, with more modifiers the higher the rarity. The mechanic-specific tablets have a simple drop rule: you get the tablet by doing the mechanic. Breach tablets drop from Breach monsters, Expedition tablets from Expedition, and Overseer tablets drop from Map Bosses. If you want a specific tablet flowing, farm that content. (You can also push tablet drops by adding the "increased Precursor Tablets found in area" modifier to your Waystones with Distilled Despair, per IGN — handy when you're short on a type.)
This is why tablets sit at the centre of the Atlas economy in 0.5. They're the connective tissue between every other system — your currency farming, your Breach and Expedition runs, and your Delirium maps all get dramatically more profitable when they're layered under the right Towers.
How do you use a tablet? (Lost Towers explained)
Here's the part that trips everyone up: you cannot use a Precursor Tablet from your inventory. Tablets only work through Towers.
Towers (you'll see them as Lost Towers on the Atlas, sometimes called Precursor Towers) are special structures dotted across the map. The process is:
- Find a Tower on your Atlas and run it like any other map. Each Tower has one of a few fixed layouts, but the goal is always the same.
- Reach the end and activate the Precursor Beacon. As Mobalytics describes it, every Tower layout shares one goal: "reach the end, and activate the Precursor Beacon at the end, which will drop a Precursor Tablet and reveal an area around the Tower on the Atlas." So clearing a Tower does two things at once — it reveals a big chunk of fogged Atlas (this is how you find Citadels, bosses and more Towers) and it opens the Tower's tablet slots.
- Place your tablets from the Atlas screen. Once the Beacon is lit, open the Atlas, click the Tower, and slot in up to 3 tablets. Their modifiers immediately apply to the maps in the Tower's radius.
That radius is the whole point. One tablet doesn't buff one map — it buffs every eligible map around the Tower. Run those maps and you're playing inside the tablet's bonuses the entire time.
Every PoE2 tablet type (and what it does)
Tablets are named after the content they add. The main types you'll see:
| Tablet | What it adds to maps in radius | How you get it |
|---|---|---|
| Precursor / Irradiated (generic) | Pure map juice — increased Item Rarity, Pack Size, Rare & Magic monsters, Gold, Essences, extra chests | Drops from any map monster |
| Overseer | Map Bosses added to maps in range (great for Waystone sustain) | Drops from Map Bosses |
| Breach | Breach encounters | Drops from Breach |
| Expedition | Expedition encounters | Drops from Expedition |
| Delirium | Delirium fog encounters | Drops from Delirium |
| Ritual | Ritual altars | Drops from Ritual |
| Abyss | Abyss cracks | Drops from Abyss |
The Overseer's Precursor Tablet deserves a special call-out because it's the sustain workhorse. Straight from the official 0.1.1 patch notes: GGG "Added the new Overseer's Precursor Tablet, a currency item which can be placed in completed Towers to add Map Bosses to valid Maps in radius." Map Bosses are valuable because Powerful Bosses always drop at least one higher-tier Waystone — so an Overseer Tower keeps your Waystone supply topped up while you farm. Maxroll's guidance is to "look for Overseer Precursor Tablets and use them liberally."
Notice the tooltip: an Overseer tablet might roll "Up to 2–4 Maps in Range contain Bosses," plus increased Quantity of Items and increased Quantity of Waystones dropped by Map Bosses as extra mods. That's three layered bonuses from one item — and exactly why rarer tablets are worth so much.
How does tablet stacking work?
This is the mechanic that separates casual mappers from currency farmers: tablet effects stack. Towers have overlapping radii, so a single map can sit under two or even three Towers at once — and Maxroll confirms "the effect of the modifiers from multiple tablets stack, and the more you use the more tablets you get back."
A few rules to use it well:
- Stack the same Activity for density, or different Activities for variety. Two Breach tablets on overlapping Towers = a much denser Breach map. A Breach tablet + an Expedition tablet + an Overseer tablet = a single map running Breach, Expedition and a boss. That's a "juiced" map.
- Quantity stats stack; some flags don't. Per Maxroll, "a map can't be irradiated multiple times, but the quantity of items and strongbox chance found does stack." So you won't double-add the same on/off encounter, but the raw quantity/rarity numbers pile up.
- Charges are the budget. Every tablet has 10 charges — it applies to roughly that many map runs in the radius before it's spent. Don't agonise over saving them; you'll out-earn the cost. (Tablets are consumed when slotted, so plan which Towers overlap your farming patch before you commit.)
- Plan around overlap. The high-end play is to find a cluster of 2–3 Towers whose radii overlap a pocket of good maps, fill every slot, and grind that pocket. Everything you run is triple-juiced.
Where do Towers fit in the bigger Atlas picture?
Towers aren't just tablet holders — they're how you progress the whole Atlas. When you first hit endgame, Maxroll's advice is to "travel to the Precursor Tower" immediately, because "this reveals a huge Precursor Fortress nearby. Completing maps inside of the Fortress gives you points in your Atlas Passive Tree" (press Ctrl-U in-game to open it). Those Atlas passive points are what give you more loot and more Waystones from every future map — so Towers feed directly into your farming power.
A few supporting systems worth knowing while you build your Tower network:
- Masters of the Atlas — Jado, Hilda, Doryani. Each runs a questline that unlocks map-modifying abilities. You can have one Master active at a time with up to 3 abilities, and switching is free. Hilda grants a 25% chance your opened map contains a Powerful Boss (huge for Waystone sustain alongside Overseer tablets); Doryani adds an extra revival and can terraform a biome you dislike.
- Waystone sustain. Use cheap, sub-tier Waystones to travel between boss maps, and save your high-tier Waystones for the boss maps themselves — Powerful Bosses always return a higher-tier Waystone. You can also reforge 3 Waystones of the same tier into 1 of the next tier up, and Doryani sells Waystones that refresh each time you level.
- Don't over-roll your defenses away. Waystones take up to 6 modifiers, but 6 mods drops you to a single portal — if you die, the map (and everything in it) is gone. On a squishy build, cap at 5.
Are Precursor Tablets worth using in PoE2 0.5?
Yes — unequivocally. Tablets are the highest-leverage, lowest-effort way to multiply your currency-per-map in Runes of Aldur. They cost you nothing but inventory and a few Tower clears, and they pay back in raw drops, Activity loot, and Waystone sustain. The only real "cost" is learning the Tower workflow once.
There's also a straight trade angle: good tablets are genuinely valuable. Because you can't simply Regal a magic tablet up to rare, high-mod tablets are scarce — IGN notes they "often go for 30 or more Exalted Orbs" on the Trade site. If you pull a clean 3-mod Overseer or Breach tablet you don't need, sell it. (One community caution: tools like Craft of Exile are currently unreliable for tablet mod weights because GGG removed the spawn-weight data from the game files — don't trust third-party tablet odds blindly. Treat poe.ninja as the source of truth for prices.)

Frequently asked questions
How do I use a Precursor Tablet in PoE2? You can't use it from your inventory. Find a Lost Tower on your Atlas, clear the Tower map, and activate the Precursor Beacon at the end. Then open the Atlas, click the Tower, and slot the tablet into one of its (up to 3) slots. Its modifiers apply to every eligible map in the Tower's radius.
Where do Precursor Tablets drop? From monsters while you map — any enemy can drop a generic one. Mechanic tablets drop from their own content (Breach tablets from Breach, etc.), and Overseer tablets drop from Map Bosses. You can boost tablet drops with the "increased Precursor Tablets found in area" Waystone mod.
Do tablet effects stack? Yes. Towers have overlapping radii, and Maxroll confirms the modifiers from multiple tablets stack. Quantity and rarity stats pile up across overlapping Towers; on/off encounter flags don't double-add, but you can run different Activities together (e.g. Breach + Expedition + a boss on one map).
What's the best tablet to use? It depends on your goal. Overseer tablets are the safest all-rounder — they add Map Bosses for Waystone sustain and extra loot. For targeted currency, stack the Activity you're farming (Breach, Expedition, or Delirium). The generic/Irradiated tablets are pure rarity-and-pack-size juice for any map.
How many charges does a tablet have? 10. A tablet applies to roughly that many map runs in the Tower's radius before it's used up. Tablets are consumed when you slot them, so place them on Towers that overlap the maps you actually plan to farm.
Why are some tablets so expensive? Rarity. You can't Regal a magic tablet into a rare one, so high-mod (3-affix) tablets are scarce — IGN notes they regularly trade for 30+ Exalted Orbs. A clean Overseer or Breach tablet is a real chunk of currency on its own.
