Atlas regions are sections of the Atlas of Worlds that contains a fixed set of maps. Each region has a citadel which allows socketing of 4 watchstones. Each watchstone can have various modifiers, changing the drops, enemies and environmental effects for maps run within that region. Since the Echoes of the Atlas expansion, each region also has a passive skill tree, that allows players to customize the type of content they wish to obtain.
Regions[]
The Atlas is split into 8 different regions, each affecting a Watchstone or Conqueror's area of influence and what item bases can drop.
If you complete a map that was created before the expansion, it will complete a chain of maps from the start pointing on the Atlas up until the tier of map you completed. Shaped and Elder items do not drop on these maps. Elder Guardians also cannot spawn from them. Shaper and Elder areas will not be influenced on the Atlas.
Introduced to the game. Non-unique maps pre-Atlas of Worlds do not count towards Atlas completion, even for maps where the map type and tier are identical to the current version. Older versions of unique maps will count towards Atlas completion, including the bonus objective, but the Shaper's Orb does not drop in old versions (affecting Lua error: Error: invalid field alias "items._pageName"; aliases cannot contain dots or quotes.., Lua error: Error: invalid field alias "items._pageName"; aliases cannot contain dots or quotes.., Lua error: Error: invalid field alias "items._pageName"; aliases cannot contain dots or quotes.. and Lua error: Error: invalid field alias "items._pageName"; aliases cannot contain dots or quotes..).
