To maximize the yield of Chaos Orbs in Path of Exile, selecting efficient farming routes and strategies is key.

1. Vendor Recipe Farming with Item Level 60-74 Rare Sets
   A foundational early-game method revolves around the Chaos Orb vendor recipe. The player collects a full set of rare gear with item levels between 60 and 74, including weapons, armor, rings, amulets, and belts. Selling this full, unidentified set to a vendor rewards one or two Chaos Orbs. Focus on maps within this item level range and run them repeatedly, selectively picking up items that fit the recipe and organizing loot efficiently to maximize orb returns. This method provides a steadier income stream for players ramping into the endgame, especially for those looking to stack buy poe 2 currency early.

2. Fast Mapping on High-Mob Density, Clear Layout Maps
   Fast mapping is the backbone of Chaos Orb farming mid-game and beyond. Prioritize maps with straightforward linear layouts that enable quick clears without backtracking, such as Burial Chambers, Toxic Sewer, or Crimson Temple. These have dense monster packs that generate more drops, increasing chances for currency. Boost map quality with chisels and invest in map mods that enhance pack size or rarity to further maximize loot. A fast, high-damage build that can clear packs swiftly is critical to maximizing Chaos per hour.

3. Targeting League Mechanics with High Monster Spawns
   Engaging in league-specific content that generates bursts of monster packs is another efficient route. Mechanics like Incursions, Legion, Delve, or Expedition spawn numerous enemies or chests, increasing loot drops and Chaos Orb potential. Allocate Atlas passives to amplify these mechanics and use scarabs or other currency to force encounters. The condensed loot rewards, often combined with map mods, create an opportunity for rapid Chaos Orb acquisitions.

4. Farming Divination Cards that Yield Chaos Orbs
   Certain divination cards reward Chaos Orbs directly or items that trade well for Chaos. Farming maps known to drop these cards efficiently, especially those with high mob density and quick layouts, adds an alternative method of accumulation. Examples include cards like "Rain of Chaos" and others which can be turned in for Chaos Orbs. Managing inventory to prioritize card picks and turning them in promptly ensures a reliable currency flow.

5. Engaging Heist Content for Steady Currency
   Heist contracts and blueprints drop consistent small currency amounts including Chaos Orbs. While slower than mapping for sheer volume, Heist is accessible to modest builds and generates regular income from completed contracts, loot drops, and rogue gear. It also adds variety, reducing burn-out compared to solely running maps. Incorporating Heist runs into farming routes can supplement Chaos Orb earnings with less variance and can even set players up with gear for cheap poe 2 currency trading later.

Efficient Chaos Orb farming in Path of Exile centers on combining fast clears in dense monster zones with smart loot management and leveraging vendor recipes. Early on, focusing on vendor set recipes in suitable maps lays a steady foundation. As characters progress, incorporating juiced maps and league mechanics will increase Chaos yield. Finally, diversifying routes to include divination cards and Heist content maintains a steady influx of Chaos Orbs while keeping farming engaging and sustainable. This balanced approach optimizes Chaos Orb income for both solo and group playstyles.
