Mission
Grandmaster Conquest: Heist Mars
Blitz the legendary BrayTech Futurescape campus on Mars to repossess fragments of the submind Charlemagne's code.
Overview
A mission in Hellas Basin on Mars: a blitz of the Braytech Futurescape campus to repossess fragments of the submind Charlemagne's code. It is the Grandmaster version of the Heist Battleground: Mars activity. 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. Power is listed at around 390-410, with 410+ recommended; other listings give higher per-mission figures. The mission has three parts: an opening area (Zones A, B and C of yellow-bar enemies), a door-defense horde section, and a boss room fight against Kelgorath with adds. Unstoppable and Anti-Barrier Champions appear and should be killed quickly. Ability-spam builds such as Solar Warlock with Starfire Protocol are recommended. The encounter description comes from an earlier Season of the Seraph Grandmaster Nightfall, which may differ from the current Conquest.
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.
