If you want to farm a lot of essences in PoE, then the best way to do so is by spamming low-tier maps. To get started, you will need to use the essence thing on the map device, and you will have access to all the nodes. By doing this, you can get up to four actual essence rewards for each map, and some maps can give you up to 18 shrieking essences with one click.

To make the most out of farming essences, you should also have a decent amount of blue harvest juice so that you can swap them around between the different ones that you want. You can focus on getting more greeds or other cool rarities, and you can farm either the Cemetery for divination cards that give divines or the Crimson Temple for the one that gives mage blood. Both of these options are great for getting the items that you need.

To maximize your essence farming potential, you can also create magic find the character with 30-40 quant and a few hundred rarities. You can use this character to farm different maps and get more taste of hates and other cool rarity stuff. To create magic and find the character, you can start by getting a Vixen's Gloves for an Impending Doom build, or you can use a Wind Ripper for a bow build.

However, it's worth noting that the Wind Ripper doesn't have enough damage, and you will need to drop a lot of magic find or survival to make it work. Alternatively, you can use a basic starter bow and work on getting a new one with tier-one stats, such as tier-one attack speed and tier-one crit.

For your magic find character's equipment, you can use a Viscous, a Goldworm, Ventures, and the Taming for some damage, along with a Hibernation Flask. You can also use an Anointed Vengeance Cascade and other items to help your character's survivability.

When it comes to choosing your ascendancy, you can opt for a Pathfinder. This choice will allow you to keep up Divination Distillate permanently, thanks to the Master Surgeon's ascendancy. You will also have many flask effects, making it easier to keep everything up permanently. Additionally, you can use the charges when you're hit, and you will have to recover four percent live, making your character decently tanky.

While fighting essences with less than 4k HP can be risky, you can increase your character's survivability by getting more life per level and more damage. You can also use jewels with life on them to increase your character's survivability. Remember to always be on the lookout for better equipment, More Poe Currency and to keep practicing your farming skills to maximize your essence farming potential.
