History of Cartographer

Overview

Cartographer is a 50-point triumph from Lightfall: complete all three Lost Sectors in Neomuna. Which seal it counts toward was not confirmed by the pages I opened.

How to complete

• Hydroponics Delta (Cabal; boss Valus Dravusk): in Zephyr Concourse, reached from the Strider's Gate landing zone. The symbol is on the wall below a helipad structure; jump onto the balcony with lights opposite it and the door opens, then enter beneath the plant projections.
• Gilded Precept (Cabal; boss Valus Tharum): in Ahimsa Park and the easiest to find. Look for a large rock formation bearing the Lost Sector symbol, go left to the pyramid that is the entrance.
• Thrilladrome (Vex; boss Agon): in Liming Harbor and the hardest to spot, because the path is behind a ventilation system many players run past. Climb the cylindrical structures near the marked building and break the metal vent doors on the right, or follow the wall north past the giant fans to a door, then take the flashing pink vent and follow the pipes left.
• Each sector must be finished (defeat the boss) once; the Solo Legend and Master versions are separate triumphs and are not needed.

Notes

The boss/faction details come from the D2 Wiki; location directions come from GG Recon and ProGameGuides-style guides and may differ slightly in wording.
