Cortex is a unique Synthesised MapSynthesised MapMap Level: 77
Map Tier: 10
Guild Character: uTravel to this Map by using it in a personal Map Device. Maps can only be used once.. The base map has a variable tier but the unique map has a fixed area level (83). The area level override prevents further modification of monster levels, such as from the atlas passive notable Deadly Nightmare. The area level can be overridden by the keystone Memento Mori, which makes the area level is 85 and the map bosses are harder, but drops 3 additional rare synthesised items, each with 3 less common synthesised implicit.

Cortex is not part of the Atlas of Worlds. There is no bonus objective for this map.

This map, however, can be witnessed by the Maven as part of the prerequisites of Maven's Invitation: The FearedMaven's Invitation: The FearedThe Maven must Witness:
Cortex,
Chayula's Domain,
The Alluring Abyss,
The Shaper's Realm,

Despite not on the atlas, this map can still be affected by atlas passive skill that affects Synthesised Map. Note that atlas passive skill cannot affect maps from Kirac's atlas mission.

Modifiers

The map has two pools of map modifiers, one draw from "synthesis global " pool (mod domain = 19), one from "synthesis local" pool (mod domain = 18).

Version history

Version	Changes
3.17.0	Introduced a new "Synthesised Map" Base Type, which all 5 Unique Synthesis Maps now use. This Map is not found on the Atlas.
3.13.0	Map tiers and locations have been shuffled (though the 'pin' locations for maps has not changed). Most maps are now initially found at a different tier. ^[a]
3.12.0	Map tiers and locations have been shuffled (though the 'pin' locations for maps has not changed). Most maps are now initially found at a different tier. ^[a]
3.11.0	Map tiers and locations have been shuffled (though the 'pin' locations for maps has not changed). Most maps are now initially found at a different tier. ^[a]
3.9.0	All 5 Synthesis maps can now drop as unique items. They can only be acquired from map bosses of Tier 11 or greater maps (or Tier 14 or greater for Cortex), or if you're very, very lucky, maybe Zana will sell you one. The Cortex map is now more commonly available from Zana relative to the other Synthesis maps, and is now always level 83 (previously had a variable level). All Synthesis maps now require a minimum level 80 area to appear in Zana's mission window. Unique maps can now drop with varied tiers based on the state of your Atlas. Maps that previously had monster level overrides (such as Hallowed GroundHallowed Ground Cemetery MapMap Level: 71 Map Tier: 4 Guild Character: Ð Item Quantity: +100% Item Rarity: +100%Unique Boss drops 3 additional Maps Unique Boss gives 2000% increased Experience 0.5 Flask Charges recovered every 3 seconds +(-2-2) to Monster Level of AreaSome dead have long envied the living. When given the chance, they take from us what they can. So we offer our suffrage. In return, they give only suffering.Travel to this Map by using it in a personal Map Device. Maps can only be used once.) now instead rely on the variable tier.^[b]
3.8.0	Overhauled as a core mechanics If you're lucky, Zana will now offer 5 new unique maps as part of her missions. Each map contains a boss encounter originally from the Synthesis league, and each can drop unique items originally exclusive to that league. Note, you cannot obtain Fractured items, nor will you have any access to the Synthesiser.
3.6.0	Introduced to the game as league mechanics

Notes

↑ ^1.0 ^1.1 ^1.2 The patch notes incorrectly stated that unique maps did not changed tier, however, they did. In 3.11, Cortex 's base tier is T9 and also have T11 and T14 variants. All variants have an area/monster level override, however. In 3.12 and 3.13, Cortex's map tiers are not changed. But other unique maps have changes in tiers.
↑ Despite stated in the patch note that unique maps do not have monster level overrides anymore, all Synthesis Maps have introduced monster level overrides since version 3.9.0. In specific, Cortex can dropped with variable tiers since circa version 3.10.0.
