Once you have opened the hound door after your first return to the Castellum in Destiny 2’s Leviathan Raid, you will head down a hallway and into the Royal Gardens, a lush jungle filled with Cabal War Beasts. When you first pop in, you will be hit with some visual overload, with light beams hitting platforms and fog everywhere. You will come to learn this room very well soon, so focus on clearing out the Loyalist War Beasts and the Beast Handlers before you go exploring.
Once all the enemies are down, you will notice two large crystals spawn at the back of the room, near the gigantic Calus statue. At the foot of the statue, there is a large, round door with three lights on it. This door leads to the Safe Room, which is crucial mechanic in this encounter.
Before the fight starts, break your team up into groups of two and four:
- Four Roamers will grab spore balls and sneak around
- Two Spotters will jump on platforms with crystals and guide the Roamers
This encounter is fairly simple to explain but incredibly difficult to execute properly due to the high amount of communication required. The gist is simple: Spotters grab crystals and stand in the light while Roamers sneak past patrolling hounds to reach glowing spores. When the Roamers make it to the spores, the Spotters channel light onto the spore to make them explode, granting a damage buff to the entire party. Do this as many times as you can before the hounds begin attacking you out of restlessness (a timer) or someone getting caught. Kill all hounds to win.
Let’s break it down by group.
When the fight starts, the Roamers should be standing on top of the Safe Room door, preparing to drop in. When the crystals are grabbed, the hounds will be unleashed and the Safe Room will open to your team. All four Roamers need to hop down and grab a spore ball from the back of the room, holding it in your hand. Once you have a spore, group up into a tight pack of four and wait for your Spotters to call out locations.
There are eight spore locations on the map:
- Middle left
- Middle right
- Far right
- Upper right
- Bottom right (next to the Safe Room)
- Bottom left (next to the Safe Room)
- Far left (under the plates)
- Upper left
Walk around the jungle toward the spore that your Spotter is calling out to you. Stay in a pack together to be sure that all spore ball holders make it to the glowing spore at the same time. If spore holders wait by a glowing spore too long without the Spotter shooting it, it will go away and no buff will be granted. Listen to your Spotters call out the hound locations and use your radar to keep a sense of where they are at all times. Never cross in front of a hound and be very careful when moving around the sides or closely behind. Only sprint when there are no hounds nearby.
Once the pack has reached a spore, huddle up together and call for the Spotter. When the Spotter shoots the spore, you will gain three stacks of Empowering Spores per spore ball hit, which should ideally be all of you (12 total stacks). Repeat this process until one of your team is caught or the hounds begin howling after becoming restless.
Spotters have the easiest but most unique job in this encounter. Ideally, your Spotters should have very good Power weapons, as they have the easiest access to ammo refills.
- Grab the crystal to start the encounter and jump to one of the platforms with a pillar of light on around your assigned side. (Spotters should be assigned right or left side of the map based on their crystal pickup location.)
- Immediately start looking for the one glowing purple spore on your side and call out its location to your Roamers.
- While you are waiting for them to move, keep an eye out for hounds and communicate with your allies about their locations.
- Once the Roamers are all in place and packed in tight, use the right trigger to shoot a beam of light at the spore, causing it to grant the Roamers stacks of Empowering Spores.
- Your Roamers will then rotate to the other side of the map and become the other Spotter’s problem (or visa-versa depending on if you are popping the first spore or second).
- Once two spores have been detonated, each side will gain a new location. Help your Roamers navigate their way to the spore and repeat the process as many times as possible.
The only other thing that Spotters have to deal with are the Beast Handlers that come out each time a spore is destroyed. Some will be snipers and stand on the doors on the left and right of the arena, attempting to kill your Spotter partner. Others will jump into the arena and chase after your Roamers. These Beast Handlers are actually very easy to deal with if you are looking for them. Simply aim with your crystal and shoot them like you would a spore (they die very quickly and also drop guaranteed heavy ammo). Just remember that you must be standing in a beam of light to shoot.
Once one of your teammates have been spotted, you damage the hounds or the hounds get restless, they will begin howling and the damage phase will begin.
Regardless of your role before, you are dealing damage now. Your team gains bonus damage based on how many stacks of Empowering Spores you were able to get, so keep that in mind when fighting. Spread out and find a hound (they hang out by the spores that you can shoot). Hit them with everything you have to lower their health but do not kill them.
After about 20 seconds or so, every member of the Fireteam needs to make their way back to the Safe Room and jump in the cylindrical door under the statue. Beware of the other hounds let into the arena, because while they don’t pose much of a threat to your health, they will knock you around and make getting to the Safe Room harder.
Once the hounds have been howling for 30 seconds, the door will seal and anyone left outside will die. Once the door opens up again, the Spotters need to jump up and grab their crystals, starting another round.
You can get into the Safe Room three times, meaning that you have four total phases to kill the hounds. Killing a hound makes the paths easier to navigate but causes the hounds to become restless far faster. To counteract that problem, do not kill the hounds — just lower their health to about one shot or so. Spend the first two or three rounds lowering their health and the final round executing the hounds.
To kill them efficiently, use close range weapons like fast-firing shotguns, swords or the Merciless exotic fusion rifle if you have it. Otherwise, drop grenades that continually do damage and use your Supers on them to take them out fast. If you are playing a Sunbreaker Titan, you can use your Hammer Strike melee to weaken them, causing them to take even more damage.
Once all six hounds are dead at once, the encounter will end and your chest will spawn by the Safe Room. Congratulations Guardian, you just completed the most demanding fight in the Leviathan raid. Return to the Castellum after claiming your reward.
