Stand on the Circular floor panels to light up an area, or toss a few flares to go faster. Keep an eye out for various Boxes like Abandoned Charts as they contain Maps or other rewards. The chance to generate each biome is dependent on the weight of all biomes at each depth. A visual representation Luckzie can be found on poe.db’s delve biome page. The mines contain many themed chests, often hidden away in dark side areas along a path. Flares are consumable items that can be used to create a temporary lit area.

General Drops

Flare uses cannot be targeted; when used, the flare drops at the character’s feet. Note that the costs of some upgrades can become discounted if a player goes unusually long without buying them.

• The deeper a delve goes into the mine, the more the Crawler’s light radius is reduced.

{

• The character’s effective darkness resistance is reduced by the character’s current depth in the mine.

• A visual representation can be found on poe.db’s delve biome page.

{

• As you delve deeper into the mine these nodes appear more frequently.

|}{

• A mission can randomly occur and the chance of this can be increased or guaranteed with related Atlas passive tree nodes.

• Some nodes on the Subterranean Chart will have no paths shown leading to them.

Subterranean Chart

When a player reaches the Azurite Mine for the first time in a given league (using any of their characters in that league) a single mineshaft entrance node is created. Fractured walls and the areas behind them will not normally appear on the minimap. A dynamite charge will destroy any fractured wall within its blast radius. As you delve deeper into the mine these nodes appear more frequently. Once you’re comfortable with the level of rewards from your Depth, you Delve sideways grabbing valuable nodes along the way.

• A dynamite charge will destroy any fractured wall within its blast radius.

• Each node has a checkpoint, a circle marked on the ground in a chamber at the center of the node.

• During delves, light is normally only present in a circular area around the Crawler.

• These are of particular note early in a league due to offering items with drop only affixes including “Subterranean” Prefixes, and “Of the Underground” Suffixes.
• But it’s more profitable to farm Delve along side other league mechanics as part of your mapping strategy.

The character follows a Crawler (mine cart) powered by Voltaxic Sulphite through the mine to a checkpoint. If you want to focus exclusively on Delving you should ignore regular monsters in the map, click the 3 Voltaxic Sulphite piles then leave and start a new one. But it’s more profitable to farm Delve along side other league mechanics as part of your mapping strategy. If the party leader’s character dies inside the instance, the portal’s destination will move to the point where the character died.
{

• A map instance’s Sulphite total is increased by the map’s item quantity bonus as well as by the map’s level.

{

• Dynamite is a consumable item used to destroy fractured walls.

• The difficulty and rewards of delves increase based on depth in the mine.

• When a player reaches the Azurite Mine for the first time in a given league (using any of their characters in that league) a single mineshaft entrance node is created.
• This means that failed delves will often not cost the full original amount.

{

• But nodes which contain Fire, Cold, Lightning, Physical, and Mana or Curse items can also be worth chasing to get items with Fractured drop only modifiers.

A mission can randomly occur and the chance of this can be increased or guaranteed with related Atlas passive tree nodes. A map instance’s Sulphite total is increased by the map’s item quantity bonus as well as by the map’s level. When a new mineshaft node is created, it destroys any previously-existing node in the same spot.
