After the community feedback and the announced reactions of the Path of Exile Developers received the preliminary patch notes for Update 3.4.3.

The update should be installed this week, until then the patch notes are still to be regarded as preliminary and can change. One of the biggest changes is that Cross-character Delve card. This means that every character no longer has their own personal azurite mine, but rather all characters in the same league explore the same mine. The progress remains, just like the upgrades of the equipment, and new characters no longer have to fight their way down from level 1.

When converting, the mine will use the highest depth level selected and "overwritten" the mine layouts of the other characters. So if you still have special encounters with other characters open, you should do them as soon as possible.

Below you will find the preliminary Path of Exile 3.4.3 notes:

Path of Exile - Update 3.4.3

Improvements to Delve

• Characters within an account and a league now share an azurite mine. The progress in the deepest mine is used as the starting point.
• The amount recovered and the cost of sulfite in the endgame have been reevaluated. You can now find significantly more sulfite in maps (especially maps of a higher level). At the same time, the cost of the segments in the mine was increased proportionally. This change is intended to encourage players to face the most demanding map content.
• Map modifiers that affect the amount of items now also affect the sulfite gained. Playing demanding card content should thus become more rewarding.
• The values of the four highest sulfite capacity upgrades have been adjusted (the largest value is now 30,000 instead of 5,000).
• The sulphite costs are now capped at 2,000 sulphite per segment (occurs from depth level 955).
• The spawn rate of sulphite deposits in The Quarry area has been reduced slightly.
• The loading time when opening the underground map has been reduced.
• Entering the azurite mine from your hiding place now creates a portal into which your group members can follow you.
• Entering the azurite mine from your mine warehouse now creates a portal into which your group members can follow you.
• You can now return to a group member's azurite mine using the underground map.
• You can now return to your hiding place by interacting with the crawler after entering the azurite mine from your hiding place.
• A portal will now open if the owner of the azurite mine leaves the area or dies before the encounter is over.
• Player markings of a group member are now visible on the underground map.
• Party members can now interact with the voltaxic generator.
• You can now buy the maximum number of torches and dynamite using [Shift] + left-click.
• The height of the torches thrown has been adjusted to improve their visibility.
• The crates in the Cursed Remains encounter will no longer automatically open once it is over.
• The Dormant Boulders encounter has been improved.
• Voltaxic Sulphite can now be found in Act 7 in the 'The Chamber of Sins - Level 1' area.
