So BASICALLY.

OPTIONAL

1. You can go in with a [Nekros] and use his ability that makes it so that enemies drop more things.
2. You can remove [Overextended] which will change your strength from 253% to 313%. Note that this will make your range 175% if you remove it. I'd advice you don't remove it.

Step 1

Go into [Sanctuary] Onslaught on PUBLIC. (important so that there's always some drops on the floor)

Step 2

Either use the 4th ability Prism when you go in which will last for 1.5s which is horrible to be honest but you still kill everyone.
Or, you can rely on your teammates for a little.

Step 3 (only use when there is a lot of energy / health / ammo on the ground)

Use Sleight of Hand. This would usually trap people, but, due to the [Explosive Legerdemain] augment, it turns all items that can picked up into BOMBS

And uh
yeah
everyone will die.
Just every 15 sec ish just use sleight of hand. This nuke won't be nuking instantly, it takes a bit of time to start nuking, almost like Octavias, just so much better in [Mirage].
