The final encounter in the Wrath of the Machine raid in Destiny: Rise of Iron has two phases. It’s a somewhat tough fight, but it is manageable if you’re patient and pay attention. Before we get into what you need to do, let’s get the basics down.
You’re going to come into a large arena and when you do, split into three pairs again then cover left, middle, and center. There will be Shock, Null, and Scorch captains, as well as Servitors of the same burns. There will also be panels in front of the Aksis that you’ll need to keep an eye on, as well.
As far as prep goes, good weapons to go in with are Exotic Swords, since their special attacks absolutely melt through captains and groups of adds. If you don’t have one, just go for your most trusted weapons and you’ll be fine. Definitely go for high power, though.
Other than that, any classes are good. You don’t need a Sunsinger warlock, though, so you should go for damage from either the Stormcaller or Voidwalker. Otherwise, you’re good to go.
