Essences and Strongboxes Hybrid Farm
This farm can actually print $$ without having to take all the map modifier amplification nodes on the tree, which is VERY rare in Path of Exile 2 (unfortunately).
Preparation:
Buy 3x tablets
Find both +1 to Essences and +1 to Strongboxes on each
You can mix/match the content types you like for these, but I like Ritual, Expedition, Abyss
Trade link for searching these tablets: https://www.pathofexile.com/trade2/search/poe2/Fate%20of%20the%20Vaal/eR66PgjnhL
Note that you have to update the COUNT section with the tablet type you prefer. Also note that I've added more affixes for you to select depending on preference.
Get 10x Omen of Secret Compartments
Spec the boss node for +1 additional Essence
Bring 60x Vaal Orbs for hitting the essences
Also bring Regal, Alchemy, and Exalts for the Strongbox modification
Strategy:
It's pretty simple: you just open Researcher's boxes, and make sure your Omen triggers on a Researcher's (it only triggers once per map).
You want to make sure that Rarity and Quant properties are on the box, so modify with currency until you see both. (Occasionally you can whiff and only hit one of the two out of 6 mods).
On Essences, if the display essence on the monster is not good, Vaal it and go.
if the display essences are VERY good, don't Vaal and go.
if the display essences are MID or MANY in number, you can decide.
Note the present value of Essence types, which can be found here:
