So, the awful secrets of Arlo get uncovered in Warframe. Was he truly a savior, or was he trying to damn the whole system? Was he a mighty threat, or a victim himself? No spoilers here, I am just going to show you how to start the Zealoid Prelate boss fight that closes out the season.
How To Start the Zealoid Prelate Nightwave Emissary Boss Fight
To start the Zealoid Prelate boss fight, the first thing to do is check above the Nightwave button in the Navigator. If you see active Outbreak Missions, then it is time to fight. Any planet with an active Outbreak Alert will have an active Derelict Assassination Mission that you can join.
This mission gives you a shot at the Zealoid Prelate. To get access to it, you need a Zealot Derelict Code. If you look at your Navigation screen, there’s a small counter above the Nightwave button that tells you how many Infested Invasions are active, and what planets they are on. This icon will only appear if there are active Derelicts on the Star Chart.
Go to the planet, then look for the Invasion icon on the nodes. Alternatively, you can click on the Invasions tab in the upper right-hand corner of the screen, and select the mission from there.
Like all Invasions, you need to complete the mission three times to secure your Battle Pay, which is a Zealot Derelict Code. When you have the code, you can access the Derelict Assassination Mission, complete it, and get your rewards. The Derelict is on a new node, in orbit around the planet where the Invasions are taking place. You can reference the image above.
So there you go, now you know how to start the Zealoid Prelate boss fight in Warframe.
