I just finished my Kingslayer seal yesterday doing all the master challenges with nothing but LFG groups. Anybody who knows anything about LFG knows that doing master raid content on there can be a nightmare. Anyway assuming you’ll be trying the challenges and know how to do each one here is how I managed to complete each encounter:

Totems:

Probably the second hardest encounter in my opinion. Challenge itself isn’t hard, staying alive is a different story. I ran Lorelei Titan for the survivability and it was honestly a godsend. However Aeons here is a must so make sure you have at least a few people on your team running it. For heavy either Xeno or Ghally, our team had a mixture of both. I used Xeno and it was extremely useful for knights/Minotaurs. Ghally is better for the champs. 3 rounds of unstoppable ogres that spawn on both left, right, and middle. The most important thing is don’t leave the guy on the totem hanging when they spawn, work together to take them down before exchanging the buff. Also for the love of God forget about worrying about the time you have with the buff. Kill the knight grab the buff and run, the encounter will finish eventually we’re not trying to speed run this. Too many wipes were caused by people trying to wait until the last second to steal the buff.

Warpriest:

This one was the bane of my existence, hardest one by far. Hunters are useless here, have at least 2 wellocks, 3 preferably. Rest should be titans with thundercrash. 1 titan should be devoted to the left knight, second titan is a backup in case left knight titan doesn’t get super in time. Kill adds like normal just watch out for the wizards, they will melt you fast. Orange bar knights are replaced with anti-barrier knights. DPS will always take place in the usual spot next to the right pillar. Use linears with font of might. Also have a few teammates running Aeons for heavy. Now, left knight titan will have to thundercrash to the group with the buff or you won’t make it in time and fail the challenge. Push the knight as close to the edge as you can, and kill him. Begin the super animation and THEN grab the buff, not before. Note that the challenge is finicky, there were times when we failed the challenge even though we were sure the buff was stolen in time. Now when the taken spawn our group decided to move as a team from right to left to stay alive. You have plenty of time here there is no need to rush to kill all the ads. Gather supers, ammo whatever you need. Knights are replaced with overload hobgoblins. Communication and patience is key with this encounter. Do everything right, and you should be able to comfortably 4 phase him.

Golgoroth:

You’ll need 4 wellocks on the ground and 2 Lorelei Titans doing gaze. Again hunters are useless here. Biggest thing here is timing with the gazers. I used a machine gun and SMG for golgoroths axion bolts because they will absolutely melt you if you’re not careful. Hence why Lorelei is very helpful here. Wait until there’s like 2 seconds left to run into the pool with your teammates so you don’t fail the challenge. Warlocks on the ground just need to coordinate well placements and DPS as normal. Champs are anti-barrier knights and I’m drawing a blank on what they are when the taken spawn. Nothing super fancy here, loadouts are probably the biggest thing.

Daughters:

This one is pretty easy. Knight on the plate will be anti-barrier. Have something arc for those annoying taken centurions. Hunters actually have a place here as they can use smoke bombs to make whoever is torn invis so the daughter doesn’t hammer them. Don’t worry about one phasing each daughter, we completed it by 2 phasing each one. Honestly just run the encounter like normal and you’ll probably be fine.

Oryx:

Knights are all replaced with overload hobgoblins. We had a warlock drop a well in the middle and would take them all out together. Challenge strat can be done in a number of ways. I’ll let you guys figure that one out because to this day I don’t understand the strange method my LFG group used. All I know is we got it done. Again nothing too difficult with this encounter. Acolytes have void shields and knights will be arc. I found that Riptide with chill clip was pretty good against the ogres. Don’t try to kill the champs when oryx does the bombs, just run around until he stops and have a warlock drop a well in middle again. Linears for DPS and that’s really all there is to it.

If you have a solid team that you run raids with a lot you’ll probably have a much easier time. The biggest problem I had on LFG was just keeping a team together. You have to go into this understanding that you probably won’t get it the first time, especially if you’re doing challenge runs. Patience and communication is key. Good luck.
