List of modifiers
Each combat area of the game, including The Twilight Strand (Act 1), has the following mods:
| Name |  | Stats |
|---|---|---|
| EverythingEverywhereExiles | 1 | Area is inhabited by 20 additional Rogue Exiles |
| EverythingEverywhereInvaders | 1 | Area is inhabited by 20 additional Invasion Bosses |
| EverythingEverywhereBreaches | 1 | Area can contain Breaches Area contains 10 additional Breaches |
| EverythingEverywhereStrongboxes | 1 | Area contains 20 extra Strongboxes |
| EverythingEverywhereTormentedSpirits | 1 | Area is haunted by 20 additional Tormented Spirits |
| EverythingEverywherePerandus | 1 | Area contains 10 additional Perandus Chests Area contains Cadiro Perandus |
| EverythingEverywhereBeyond | 1 | Slaying Enemies close together has a 50% chance to attract monsters from Beyond |
| EverythingEverywhereHarbingers | 1 | Area can contain Mysterious Harbingers Area contains 20 extra Harbingers |
Note that GGG may disabled some of the modifiers. For example, all editions of the events so far, did not have Beyond and Perandus mod enabled.[2][3][4] In addition, 20 Harbingers mod is added to the 2020 events, but not in 2017. The November 2017 events was held in parallel with Harbinger league.
In some case, some mod appear to an area but not actually affect it. Such as rogue exiles are not actually spawning in The Tidal Island , probably for balance reason. While for The Twilight Strand (Act 1), GGG declared the extra modifier does not appear in that area. However, in fact it does, but only Breach and Torment mod works, while mods such as Invasion, Rogue Exiles and Strongbox does not.
Moreover, the modifiers did not have the league flag property. Unique items that specific to the past league CANNOT be acquired from the above area modifiers. E.g. Anarchy, Ambush, Invasion and Torment league.
However, since Harbinger unique pieces are tied to The Beachhead maps while Breach unique are tied to Breach monsters. The above restriction does not apply.
