Delving is a great way to get in-game currency. The more you do, the more rewards you get.
The Atlas Passives are a great help with this as they increase your Sulphite generation and spawn more Azurite when you complete a map.
Niko missions spawn piles of Voltaxic Sulphite that are very valuable depending on the map tier and your character level.
1. Azurite
The deep blue monoclinic crystals of azurite are highly prized by mineral collectors, and specimens of exceptional quality can sell for hundreds, thousands or even tens of thousands of dollars. It can be found in copper deposits and is often associated with malachite. It also forms a variety of crystal shapes including masses, tufts, rosettes and crusts. Azurite is sensitive to heat and slowly weathers to malachite over time.
The combination of azurite and malachite is known as azurite-malachite, or sometimes called a “stone of heaven” or celestial energy. It has been said to promote intuition, increase creativity, dispel egocentric characteristics and open spiritual channels.
In Path of Exile, azurite is a keystone resource for crafting, providing all socket colors and the majority of links. It is also the primary currency of delve, allowing players to purchase resonators and fossils from Niko. Early on, azurite should be prioritized over most other resources as it can provide significant profit and experience rewards.
2. Sulphite
Sulphite is a resource that can be traded for valuable items in the market. It is also a very profitable currency to farm in delve. Players can collect it by reaching any node that rewards the player with Fossils, and by collecting it from special nodes like Atlas chests and Vaal Outposts.
Another way to obtain Sulphite is by farming the Fractured Walls. These are side passages hidden in the darkness of a long delve corridor and can conceal a variety of loot, including Fossils and Resonators. Players can easily reach these by using their Flares to avoid the darkness damage and dynamite to break them.
These walls are very common at the higher end of the depth scale, especially in City biomes with a Delve Boss. However, the perks gained from farming them (such as Increased Atlas Passive Generation and Sulphite Production) don’t apply to rewards earned within a map itself.
3. Divination Cards
Divination cards are a new form of currency that drop in specific locations in the cheap poe currency and grant players a unique reward. They allow players to systematically farm specific items rather than relying on random chance to acquire them.
A full set of divination cards can be vendored to Tasuni in Highgate or Lilly Roth at your hideout in exchange for an item listed on the card. These cards also have a high chance of dropping from bosses and in the Maps’ strongboxes. These cards are stackable and tradeable, taking up one inventory space.
They can be found all over Wraeclast, but some cards are more valuable than others. A good example is the Choking Guilt divination card, which can be rewarded by defeating the Eater of World’s little brother in Blight Ravaged maps. Unlike most divination cards, this one doesn’t seem to be affected by any quantity modifiers. This makes it a great farming option for many players.
4. Orbs
There is a large number of people who believe that strange balls of light caught on still images or video are the spirit of deceased loved ones. Others believe that these orbs are simply a manifestation of paranormal energy or spirits trying to communicate with humans.
Depending on who you talk to, there are also people that believe that orbs can be used for magic and that they are a portal into another world. This is an idea that has not been scientifically tested.
In Path of Exile, orbs are a special type of currency that can be used to transform items in specific ways. There are three basic orbs that can be used to change an item’s appearance, quality or stats. In addition, there are two types of meta-crafting modifiers that can be applied to an item with orbs. These are called ‘Fossils’ and ‘Resonators’. The Fossils are a separate type of currency that can be socketed into Resonators to change the crafting behavior in a specific way.
