In the Pyramidion nightfall, is there any reasonable way to approach the last phase of the Brakion boss fight? It always just devolves into chaos and "revive, grenade, rocket, die, repeat". I've finished it multiple times including prestige, but that last section is just always a shit-show, and it seems like there should be some kind of strategy to do it without dying.
How far into it until you hit chaos? I'm going to guess final damage phase, but I'll start at the beginning.
There are many different approaches, but I've had
plenty of success with this strategy.
tldr; Kill all the adds then damage the boss. The only exception is when the boss loses its head. When that happens let it come to your group then use supers, heavies and grenades to finish him off.
As soon as you drop down assign rings (left and right) to everybody. Everyone stands in the first ring to start the encounter. Damage the boss when possible, but the person or persons that plan to activate the left ring need to be moving in that direction before the boss teleports. After the boss teleports you can throw a grenade at it before the shield goes up. Then everyone throws grenades to the left side then to the right side where the enemies spawn. When the boss shields go down the first time the left side team should again already be in position to start activating the next left side ring. This saves time. Once the left ring is activated a second time everyone meets at the second right ring.
This right ring is going to be your home for a bit. Warlocks should drop rifts and Titans should set up shields. Hunters should stand around evaluating their poor class choice. The boss will first teleport to its right (your left.) After doing enough damage adds will spawn. Throwing grenades at adds is a good idea to keep their numbers down. You can easily do this while avoiding boss damage thanks to cover and subclass abilities. After the adds are dead damage the boss. You can do both at the same time just try to keep add numbers manageable. As soon as cover disappears move up the steps to your right for the next bit of cover.
* Again kill all the adds from here. You should still be in a tight group. Adds will move up the steps to get you which makes them very vulnerable to grenades. You should have enough time to always be killing adds. The only exception is when the boss loses its head. When the boss loses its head it will go ultra-aggro. Let it come to you and as soon as it is in stomp range everyone should dump heavies, activate supers, and throw every grenade available at the boss. The combined firepower should melt his last bit of health.
I'm a few beers in so if I missed anything let me know. If you have any questions feel free to ask.
-Edit 1: I already see one thing I forgot. If everyone is dead don't revive one at a time unless you are confident you can revive everyone else. There are so many adds that they will absolutely melt you if you spawn one at a time. Wait until everyone's timer is up then spawn together.
Anyone that needs help on PS4 hit me up. Approaching 80 clears.
*Giant Asterisk: I have played this mission many times and I still don't quite understand cover behavior. Sometimes it doesn't activate when it normally does.
