Destiny 2 - Leviathan Raid - Dog Section
Perhaps one of the most annoying encounters in the whole raid is this stealth room. The room itself is actually surprisingly easy, which you might be able to tell from the video I have a good handle on where things will be, as there is a certain amount of predictability. Sadly, my teammates were not powerful enough to one phase it and allow me to make a video, something that is even easier given that Xur is selling Merciless this week, but still helpful. For those looking for more tips, here is a small guide.
Start by assigning spots to people. The locations are left by the safe room, in the broken tree and the place I go to, with the right being the back two spots, seen at the start of the video, plus the other location by the safe room. If this is confusing, just alert the dogs, figure out where they run and pick a spot. Trust me when I say this is the best way to do it.
As for the rest, the fight actually has a pattern. We found that there is always a starting location, at least for the first set, near the start. Depending on which side it appears, the next one will appear on the opposite side. For the left, that would be mid/far and for right it's the furthest one by the rock. From there, there should always be another one on the same side. This is stupidly easy to get if you're on the right, as you can quickly see the one near the entrance and going to the rock one is the safest way to move back. If it isn't at either of those locations, it should be near the front.
Depending on your actual power, getting these is enough to complete the event. I can personally kill my dog, solo, with a stack of 36 without the need of my super. One or two people in my group couldn't, so make sure everyone can do it before you push for a one phase win.
As for moving, it's always safe to get left at the start, with right requiring a slight wait. If you see the dog turn the corner, it's safe if you don't run/get too close to it.
For the next one, if you're on the right, move back to the safe room and wait for that one dog to move the other way, followed by entering the tree. Have a teammate call out when it's safe and then go there, followed by returning. Ideally the last one will be next to the safe room, making for an easy 36.
Left side is a lot easier. After rushing left, move right and just wait to the broken rock, go through the crack and then wait in the bushes. When the dog on the right moves away, press forward. Depending on your luck, it will be a freebie in the rock or a slight wait behind the pillar. If it's at the start, simply return to the rock, wait for the dog to turn the corner, assuming your partner says it's not safe and then go there.
A lot of these elements can be seen in the video, but the point is that this is a surprisingly straightforward fight.
