Extra Content

Extra Content is a keyword that represents content and league mechanics from previous challenge leagues that can be encountered randomly in Maps, some of which are also encounterable in the Acts.

By default, most sources of Extra Content appear at a base chance of approximately >8% in maps. Older mechanics may have different spawn chance calculations which have never been officially published in patch notes. Some of these chances can be increased by various Notables and small passives on the Atlas Passive Skill Tree, or reduced to 0% through various Notables. Things that modify the rate of Extra Content do not prevent it from being spawned via guaranteed encounters e.g. Scarabs, map crafting options, or map modifiers.

On the other hand, the keystone Back to Basics both reduces random spawn chance of all Extra Content to 0% and prevents adding encounters manually.

Currently, Extra Content includes the following:

*Beyond Demons, Harbingers, Tempests, and Affliction Wisps are not encountered naturally and require atlas passive skills or other means to add them to areas.

Note that previous league mechanics that did not go core (e.g. Invasion, Rampage, Talisman, Warbands, Synthesis, Sentinel, Lake of Kalandra, Crucible, Trial of the Ancestors, etc.) are not considered Extra Content. Vaal side area and Trials of Ascendancy are also not considered Extra Content. Other former league mechanics that were part of the core game but were subsequently removed (e.g. Prophecy, Nemesis, Bloodlines, Archnemesis, Perandus, Metamorph) are not considered "Extra Content" as well.

Version history

Version	Changes
3.24.2	Tempests and Affliction Wisps are now considered as Extra Content, and will no longer be present in Map Areas with the Back to Basics Atlas Keystone Passive allocated.
3.24.0	The definition of Extra Content has changed to include wild masters and certain league mechanics such as Beyond and Torment, based on new Back to Basics keystone's reminder text. [Ruthless-specific This patch note only applies to Ruthless mode and does not affect the main game mode.] Einhar, Alva, Jun and Niko missions are now part of the pool of available outcomes for extra content individually.
3.23.0	Ultimatum has been added to the core game, replacing Metamorph. You will have approximately an 8% chance to find the Trialmaster and his Trials of Chaos in Maps. Metamorph has been removed from the core game.
3.20.0	We want to improve on the concept that the Atlas Tree allows players to invest into leagues that they enjoy, and have added new clusters to the passive tree for league content that can be blocked through Atlas Passive Skills. We've also increased the chances for such league content to appear.
3.18.0	The chance for Map Areas to contain a Mirror of Delirium no longer increases by a small amount for each other league, atlas or master mechanic that appears in that area. Instead, Map Areas now have an 8% chance to contain a Mirror of Delirium, with campaign areas from the Torched Courts onwards having a slightly higher chance. Added a new Atlas Keystone Passive Skill, Stream of Consciousness, which grants "Your Maps cannot be modified by Fragments" and "Your Maps have 50% more Base chance to contain Extra Content". "Extra Content" as a keyword is introduced (see: Stream of Consciousness)
3.14.0	Increased the chance for Map Areas to contain The Sacred Grove by 60%. The chance to encounter a Zana mission requiring you to complete a Harvest encounter has also been increased by the same amount. Reduced the chance for Map Areas to contain Abyss, Ambush, Blight, Breach, Domination, Essence, Heist, Legion, Metamorph and Torment encounters by 20%. The chance to encounter a Zana mission containing any of these mechanics has also been lowered by the same amount. Reduced the chance for Map Areas to contain a Delirium Mirror by approximately 20%. The chance to encounter a Zana mission containing a Delirium encounter has also been lowered by the same amount.
1.0.0	Rogue Exiles will start to spawn in all leagues (including Race events) at around 60% of the rate that they appear in Anarchy.
