It’s actually pretty easy if you have all Rasputin upgrades and appropriate champion killing weapons (like Eriana vow, divinity, raid exotics if you don’t have either). You probably will still die a bit, but all you have to do is just abuse valkyries and heavy frames, while also making sure to stun champions while doing so (you can drop your Valkyrie, stun a champion, then pick it back up if it hasn’t dissipated by then). Just abuse Rasputin upgrades, and you’ll be fine. If you don’t have them, then you’ll probably have to either do it slowly or get a fireteam together.
