Bracus Zahn

Bracus Zahn is the boss of the The Arms Dealer Strike in Destiny 2. He is a notorious weaponsmith having been targeted by both the Tower Vanguard and Emperor Calus for supplying weapons to the Red Legion.

Overview
Bracus Zahn is a Cabal officer distinguished by his unusual green armor. He leads a contingent of similarly-armored Red Legion soldiers, possibly renegades or criminals based on their titles. Zahn carries multiple weapons and will switch between them throughout the fight against him, due to his role as a weaponsmith and arms dealer.

Gameplay
Upon the initial confrontation, Zahn will jump from a Cabal ship onto another platform, where he will summon Volcanic Scorpius along with other Cabal. He will be armed with a Slug Rifle for this first section. After doing some damage to him and killing all other enemies, he'll jump to a second platform and do the same thing. Once again, after doing damage to him and killing adds, he will fly upwards and into an airfield. The player must activate a lift and kill more Cabal foot soldiers to continue the fight. Once the lift has reached the top, Bracus Zahn will be waiting at the top armed with a Cabal Headhunter sniper rifle, which can punch through Guardian shields with ease at long range, and at close range he will use his jump jets to create a shockwave that will knock players back a significant distance and into greater dangers. This shockwave will leave behind spots of fire that ignite anyone that steps in them. He will summon four Volcanic Scorpius. At this point, the player can start doing permanent damage to the boss. Every third of his health that is taken down, though, Zahn will fly onto one of two pillars and surround himself in a shield. The only way to remove the shield to continue the fight is to pick up a Flame Core (which appears after enough adds are killed and a Cabal Thresher removes a Goliath Tank on top of it) and "dunk" it into a receiver on the opposite side of the map, similar to earlier in the Strike. Throughout the encounter, smaller Cabal enemies will continue to spawn. When at 50% health, Zahn will switch his equipped weapon to a Cabal Slug Shotgun.

Trivia

 * Bracus Zahn may be part of the Sand Eaters as both him and the Eaters have green coloration. This may just be a coincidence as Zahn has more green on his armor and said coloration is much brighter. This bright green armor color may be the mark of a Cabal Arms Dealer as we haven't seen any other Arms Dealers yet in Destiny.
 * It is possible to deal enough damage in a short enough time to force Zahn to skip going to one of his hiding spots, so players looking to complete the strike as quickly as possible are in luck.
 * The Arms Dealer Strike is Suraya Hawthorne's initiation of revenge against Zahn. His manufactured weapons have killed many of Suraya's people.
 * In the Destiny 2 official guide, Bracus Zahn is listed as a Legionary.
 * Also in the guide, Zahn bears the title of Primus. This could be a mistake or a feature altered through development.
 * In the Tilt Fuse lore tab, it hints that Bracus Zahn once supplied weapons to Emperor Calus before he was deposed. Zahn also seems to have a hatred for the Red Legion and their leaders because of that.
