As you venture through Path of Exile 2, there will be times when you hit a roadblock or need some extra levels to progress. Farming XP can be an effective way to prepare for tougher encounters, gear up, and improve your overall power. This guide highlights some of the best farming spots throughout the campaign and endgame, where you can grind for XP while taking a break from the main progression.

1. Best Act 1 Farming Maps: The Hunting Grounds & Ogham Village

Act 1 can present a difficulty spike, especially when you face the Geonor boss. If you find yourself under-leveled or lacking sufficient gear, head to Ogham Village for solid XP farming. The map is simple to navigate, and the Executioner boss provides decent XP and loot.

Another great Act 1 farming map is The Hunting Grounds, where you'll need to defeat Crowbell, an optional boss that rewards you with extra passive skill points. This map's high mob density makes it a good option for leveling up.

Key Tips:

Kill Crowbell for additional passive skill points.

The Executioner fight in Ogham Village is excellent for loot and XP.

2. Best Act 2 Farming Maps: Keth & Mawdun Mine

Act 2 introduces more difficult mobs, and players may need to farm for better gear or build defenses before progressing. Keth is a reliable farming map, with the Kabala the Constrictor Queen boss being fairly easy to take down.

Another map worth noting is Lost City, which is connected to Keth and features the Ninth Treasure of Keth, another optional boss. Running both Keth and Lost City repeatedly will ensure ample XP.

Key Tips:

Kabala the Constrictor Queen is an easy-to-defeat boss for decent XP.

Generate new instances of Keth and Lost City for maximum farming efficiency.

3. Best Act 3 Farming Maps: The Jungle Ruins & Utzaal

In Act 3 (or Act 6 on Cruel Difficulty), The Jungle Ruins is a great map to farm early in the act. It features Mighty Silverfist, an optional boss, along with several elite enemies and other minor bosses. This map has decent mob density and can help you gain XP before tackling the tougher content in Act 3.

For later in the act, Utzaal offers Viper Napuatzi, an optional fight. This map is one of the best XP farms in Act 3, thanks to its wide-open spaces and large mob density.

Key Tips:

Mighty Silverfist is a reliable boss for loot and XP in Jungle Ruins.

Utzaal has great mob density and the Viper Napuatzi fight, which provides solid XP.

4. Trial of Chaos: Trial Mastery

The Trial of Chaos is replayable content that allows you to gain passive points for your ascendancy class. While its primary purpose is for ascendancy progression, it's also a good spot to farm Vaal loot and some XP.

You can re-run this trial starting from Act 3 onward, using an inscribed ultimatum. While it's not the most efficient XP farm, it offers some decent rewards as a side activity, especially if you're focused on grinding for Vaal loot.

Key Tips:

Focus on re-running the Trial of Chaos with inscribed ultimatums.

Ideal for grinding Vaal loot alongside XP.

5. Farming Endgame Maps: Juicing Waystones

Once you reach the endgame in Path of Exile 2, the difficulty curve increases and the farming opportunities become more dynamic. Waystones are essential for crafting high-tier maps, and you can "juice" these Waystones with magic and rare modifiers to increase mob density and add elite enemies.

The best Waystone modifiers to look for are those that increase mob density or provide elite enemies, which result in more monsters and better XP per map.

Key Tips:

Look for Waystones with increased mob density or elite enemies.

These modifiers can drastically improve XP farming in endgame maps.

6. Farming Expeditions: Excavation Time

Excavation farming comes into play as you reach the endgame, particularly after meeting the NPC Dannig, who unlocks Logbook Expeditions. These expeditions allow you to complete much larger excavations, with 20 explosives at your disposal instead of the usual 5. The bigger the excavation, the more enemies spawn, providing tons of XP and loot.

Key Tips:

Complete excavations until you meet Dannig and unlock Logbook Expeditions.

Chain Remnants and Runic Monster spawns for massive enemy packs and higher XP returns.

7. Farming Breach Events: Breach and Clear

Breach events are an excellent endgame farming activity, where waves of monsters spawn in a Breach zone. This event offers solid XP and valuable endgame currencies and loot. When playing in endgame maps, you can use Waystone modifiers to increase mob density or spawn more elite enemies, making Breaches even more profitable.

Key Tips:

Look for maps with Waystone modifiers that guarantee Breaches.

These events are highly effective for XP and loot farming in the endgame.

8. Farming Simulacrum Events: Wave After Wave

Similar to Breach events, Simulacrum events are focused on waves of monsters that you must clear to progress through each wave. Simulacrums tend to have more monsters per wave, making them a great source of XP and loot if you can clear them effectively.

However, Simulacrum farming is often more focused on generating Simulacrum Splinters and loot than XP. Still, for players in the probing their builds, the early tiers of Simulacrum events can yield excellent XP.

Key Tips:

Focus on early tiers of Simulacrum for great XP farming.

Simulacrum Splinters are valuable, making this a dual-purpose farming activity.

Act 1: Ogham Village and The Hunting Grounds (for solid XP and additional passive skill points).
