You will need to find the Forge Drones in the Izanami Forge if you want to gain maximum temperament from your races. Destroying both will set the Forge to maximum Temper, which will allow you to progress in the Mysterious Box quest for Izanagi's Burden Exotic Sniper Rifle.
Where are Izanami's Forge Drones in Destiny 2?
The Izanami Forge is located on Nessus. Spawn at Architect's Edge, then head to The Hollows and descend to the lower level. Stay to the right and go around the cave. You will see a small Vex portal hanging on the wall. Go there to find the path that leads to the Izanami Forge.
The Forge consists of three platforms. The central platform is where the Forge itself can be found, while the platforms to the left and right add up while the Forge is in progress, each of which also spawns a drone. of Forge.
The Forge Drone on the right will appear next to the high column in the image above. It is quite easy to see from the central platform.
The Forge Drone on the left will spawn right next to the outermost pillar on the right when facing the platform from the center. If you need to get both Drones, it is best to stand on the central platform for the duration of the race. You'll need to deal with a busy platform and make sure any orbs thrown by your teammates make it to the Forge, but you can be sure you'll remove both Drones after they spawn. You just need to equip a sniper rifle to do so.
Now that you know where the two Drones appear, remember that you don't even have to kill the boss. All you need to do is complete a max heat race and progress through the quest.
