Magister's Terrace Mythic+ Dungeon Guide

This encounter alternates between a main boss phase and an intermission phase, where a big focus in both is space management, thanks to a couple different mechanics creating area denial.

Starting with the boss phase, Arcane Expulsion does a moderate group hit that knocks back all players and drops a puddle underneath the boss for 2mins, so I recommend positioning the boss towards the outside of the arena, overlapping existing puddles when possible. To make positioning a bit more difficult, tanks will also need to beware of Repulsing Slam, an arcane hit and knockback targeting them specifically. For both knockbacks, players are able to use the walls or staircases around the room to prevent themselves from being moved.

When the boss reaches 0 energy the intermission phase begins, with the boss becoming stationary as it pulls Energy Orbs from the edges of the room towards itself. If these manage to reach the boss they’ll deal a heavy hit of group damage and give the boss a stacking 20% damage increase, so players will want to make sure to block them, just be careful because when soaked these orbs also leave behind a puddle for 2mins on top of applying the stacking Unstable Energy DoT for 3s to the soaker, so try and soak them near existing puddles and either stagger your soaks or use a defensive when soaking multiple back-to-back.

There are a couple other important things to note about the intermission phase. First, the boss also takes 20% increased damage for the 20s duration, so if possible save offensive cooldowns for this phase for some extra value. Second, I recommend bringing the boss into one of the side alcoves just before the intermission starts, which causes the orbs to funnel towards your group, making them easier to soak. That means you’ll want to make sure you aren’t filling these alcoves with puddles during the boss phase, instead filling up the more central areas first.

Throughout this fight you’ll be interacting with the Suppression Zone dropped by the boss shortly after being engaged, though it’s important you don’t spend too much time inside it does pacify you. For the initial spawn as well as ones later in the encounter, I recommend dropping this zone in the middle of the room, allowing your group to loosely spread around it to prevent cleaving from the Runic Mark debuffs.

This DoT is the main source of group damage, targeting 2 players at a time and dealing splash damage to anyone nearby. The only way to remove it is by stepping inside the Suppression Zone, which also triggers Null Reaction, dealing AoE damage, creating circles to dodge, and applying a stacking slow.

Since this is a fairly substantial hit of damage, you’ll want to stagger clearing this debuff, though beware that if you’re the 2nd player to clear your debuff you’ll be in significantly more danger, so you may need to press a defensive. On top of this, since this debuff can also target the tank, it’s smart to allow the non-tank player to clear their debuff first, as it’s much safer for the tank to hold onto the DoT for longer.

Speaking of the tank, the main source of additional damage comes from the Hastening Ward Magic buff the boss occasionally gains, so be ready with a defensive when this gets applied, or if your group has access to a purge then use that to remove it entirely.

The last ability is Wave of Silence, another AoE hit that will pacify players for 8s unless they are safely inside the Suppression Zone, so make sure you’re healthy for when this cast goes off, and step into the zone just before it completes.

This is an interesting boss encounter that increases in target count over time thanks to the Triplicate ability, which the boss uses shortly after being pulled and then again at 50% health to create 2 clones that are untankable but share health and slowly patrol around the room, duplicating ability casts. Tanks will want to do their best to move the boss such that you’re able to cleave it along with as many clones as possible.

In terms of the abilities, they always happen in the same order, with the boss and each clone focusing on a different player for their casts.

First up is Cosmic Sting, which deals a hit of shadow damage and drops a puddle underneath the target on contact, so try and drop these off to the side or out of the path the boss is currently moving in.

Following these hits, the boss and clones will gain an absorb shield then debuff the same set of players with Neural Link, causing them to take 20% more damage for 12s or until they touch the clone linked to them, which also removes the absorb shield. If you’re not sure which clone you’re linked to, look for the arrow under your character which points towards it.

You’ll want to be quick with removing this debuff as it’s shortly followed by Astral Grasp, which pulls players towards their linked clone, dealing shadow damage to them while also dealing heavy damage to anyone who gets within 4yds. If you still have the damage amp when this happens you’ll want to use a defensive, otherwise make sure you fight this pull-in.

From there the abilities just repeat, where eventually all 5 members of your party will be targeted by every set of abilities, so it may be beneficial to save damage, healing, and defensive cooldowns for when 5 boss mobs are active.

Once Gemellus has been defeated you can make your way up the tower towards the final boss, where on the way you’ll encounter more of the void related trash mobs you just fought.

As for the boss arena itself, you’ll notice 4 statues evenly spread out around it, which will divide the room into 4 quadrants after pulling the boss with the Void Torrent beam, so you’ll want to pre-emptively spread out such that there’s at least one player in each quadrant. I recommend doubling up your healer with a DPS player, with them being next to the tank to ensure your healer is always in range of them, to help with the Hulking Fragment Magic debuff.

When this ability is cast, it deals a large shadow hit to the tank and anyone within 8yds of them, which is why I recommend tanks being alone in their quadrant. On top of this it also applies a 30s Magic DoT that leaves behind a moderately sized puddle for 40s on removal, so you’ll want to back up out of melee and get dispelled away from the boss to drop this off out of the way.

Note that while the boss is stationary, he doesn’t actually use melee swings and instead casts Entropy Blast at the tank, so leaving melee range does not have any negative side effects.

Outside of tank abilities, the main mechanic is Unstable Void Essence, which is a soak that deals a hit of shadow damage to the soaker and bounces between each quadrant once per cast, which is why you want your group spread out, as if you ever miss a soak it applies a 40s DoT to your entire group, making it much more difficult to heal.

To add some additional damage on top of the soaks, players will occasionally be debuffed with Devouring Entropy, a DoT that has variable duration, so if you get unlucky and get a long debuff or if you have the debuff while you soak, you may want to be ready with a defensive or health potion.
