Mission

Grandmaster Conquest: Arms Dealer

Stifle the legacy of a notorious ironmonger providing weapons to the Shadow Legion.

Overview

A mission in the European Dead Zone about stifling the legacy of a notorious ironmonger who armed the Shadow Legion. It is a Grandmaster-difficulty Conquest mission, played from the seasonal hub in The Portal as part of the Monument of Triumph content. The six Grandmaster Conquests are Grandmaster Conquest: Arms Dealer, Grandmaster Conquest: Defiant EDZ, Grandmaster Conquest: Disgraced, Grandmaster Conquest: Heist Mars, Grandmaster Conquest: Heliostat and Grandmaster Conquest: Scarlet Keep.

Power and difficulty

Grandmaster Conquests are fixed, hand-configured activities with Champions (Barrier, Overload and Unstoppable can all appear), limited revives with Extinguish, Surges and a Power disadvantage. One guide puts GM Conquests around 390-410 Power with 410+ recommended; other listings give higher per-mission Power, so check the in-game recommended Power. Encounter details were not confirmed from an opened source; this page is a stub.

Rewards

A first clear gives a one-time Tier 5 engram. Clears count toward the Grand Conqueror triumph (four GM Conquest clears) for the Conqueror seal, and the seal can be gilded each season by re-clearing that season's Grandmaster Conquests.
