*Need Help* Want to Get The Exotic Sword ~XboxOne~

Alright, so getting the exotic sword requires at least 3 people to kill Alak-Hul and the Warden of Oryx. We have to kill the Warden of Oryx, and then kill Alak-Hul in 30 seconds.

I'd like you to read the whole thing so you know what you're doing, but it's not required. I'd like to do it on Saturday (November 14th) but I haven't worked out whether I can do that or not. This is a preemptive post. My GT is CaseyTheTomato, I have a mic but prefer not to use it.
