Welcome to the Path of Exile currency farming guide. In this article, we will focus on the Harvest League and growing Hordes, which can be a lucrative way to make currency in Path of Exile. We'll discuss the tree, the Atlas, and the setup you need to farm Poe currency, as well as some tips for maximizing your profits.

First, let's talk about the tree. The most important nodes to get are the Harvest nodes, as these will increase the chances of getting life force and crafting materials from the Harvest. Other important nodes include map drops, duplication nodes, and saving extract points. The rest of the points can be allocated to strong box nodes or other flex points that suit your playstyle.

For the Atlas, the most important sextants to use are the Harvest sextant and the Beyond sextant, as these will increase the chances of getting life force and rare monsters respectively. Magic pack-size sextants can also be useful for increasing the number of monsters you encounter.

To maximize your profits, it's important to use scarabs, which can be obtained through in-game content or purchased from other players. Polished scarabs are the cheapest and can be used to increase the chances of getting maps, which can be sold for profit. Other scarabs can be used to increase the chances of getting specific drops, such as divination cards or currency items.

For the setup, you will need to use the map device to guarantee the Harvest. This will cost around 12 chaos, but it's worth it as it will increase the chances of getting life force and crafting materials. Additionally, it's important to have good clear speed and a strong build to clear the Harvest quickly.

During the farm, it's important to focus on getting as much life force as possible, as this is the main source of income from the Harvest. The other drops, such as currency items or divination cards, are secondary sources of income.

In terms of profitability, the average return on investment for this farm is around 69 divines for 100 maps, with a total cost of around 26 divines. This is mostly due to the high value of the life force and extract alters, as well as the sextants and chaos orbs that drop from rare monsters.

In conclusion, the Harvest League and growing Hordes can be a profitable way to farm currency in Path of Exile. By focusing on the Harvest nodes, using scarabs, and having a strong build, you can maximize your profits and make a significant amount of currency.
