Priory of the Sacred Flame Mythic+ Dungeon Guide

As mentioned previously, this boss must be fought with at least 1 of his Trusted Guards, who gain Bound by Fate while near him, drastically increasing health but also causing them to share damage. On top of this, the Trusted Guard despawns upon killing the boss, so you never need to outright focus this mob, however you do still gain boss damage by cleaving it.

In terms of which Trusted Guard to fight with the boss, as I mentioned previously for all groups I think Taener Duelmal is the best choice, as the damage done by his Fireballs is relatively low meaning you don’t need a consistent kick rotation until extremely high key levels and you only need to focus on making sure every cast of Cinderblast is interrupted. This means that you’ll want to make sure that you kill both Guard Captain Suleyman and Forge Master Damian, which is taken into account in the route linked in this article.

Moving onto the boss himself, he also has his own important interrupt in Battle Cry which will deal damage and enrage the Trusted Guard if successful, so make sure you also have one player assigned to kick this ability. He will also occasionally use Hurl Spear at a random player, which is just a line attack that needs to be avoided.

Whenever the boss reaches full energy he’ll use Savage Mauling, leaping to a random target and immobilizing them as he channels physical hits. To stop this cast you must break the absorb shield on the boss, so if the boss is approaching full energy start to pool your damage for when this cast happens, and if you’re the target it’s best to use a defensive ability here.

Other than that there’s just the tank hit in Pierce Armor which also applies a nasty bleed, so use defensives and bleed cleanses if you have them to mitigate this damage.

This encounter has a lot of player target ground effects that go out on multiple players at a time, so because of this my general recommendation is to try and play as a group, baiting these effects into the same area before moving together to safely avoid them

Before getting into those abilities it’s important to mention Vindictive Wrath, which lasts for 20s and is cast when the boss reaches 100 energy. While active this will increase the potency of all other spells cast, so everyone will want to be aware while this buff is running.

To start there’s Hammer of Purity, which drops an AoE under 3 random players that explodes into multiple spinning hammers that spiral outwards. As previously mentioned, you have a lot more safe space if you group this AoEs together, so I recommend pulling the boss to one side of the room, stacking up, then running across the room when this cast goes out. When empowered this ability now targets 5 players, meaning more hammers will be spinning around the room, however if using the recommended strategy this ability is the least impactful when empowered.

Next up is Sacrificial Pyre, which spawns a circle on one of the points of the compass in the centre of the room. After 30s this circle will explode for lethal damage, so to prevent this you’ll need to have players run into the circle, which deals a pulse of raid damage and applies a stack of Sacrificial Flame to the soaker while knocking them back. Usually this requires 3 soaks to remove entirely, however if empowered it will be much larger and require 5 soaks, leading to a lot more group damage. The DoT applied to soakers can also get dangerous very quickly, so use things like immunities to soak without gaining the DoT and rotate who your soakers are. Tanks are usually safe to take 2 stacks here if they also pop a defensive so that can be quite helpful when the ability is empowered. Remember not to soak all the stacks too quickly as each soak releases a hit of party damage!

Burning Light is an important interrupt on the boss, so make sure everyone is watching for this cast. When empowered the cast time on this spell is halved, so you need to be quick to make sure the boss doesn’t heal.

Finally there’s Castigator’s Shield, which is fired at 3 random players, dealing damage and slowing them while also spawning a 12yd AoE under them that explodes after a few seconds. This is handled in the same was as Hammer of Purity, just have your group be relatively stacked and move as a unit away from where these circles spawn. When empowered this attack targets all 5 players, so there’s more group damage happening and a couple more circles to avoid.

To start out this fight you’ll take on the Prioress on the lower platform until she reaches 50% health. While here try and keep kicks on her Holy Smite cast, as this can deal excessive damage to your tank if left unchecked. There are also a couple things you’ll want to avoid, the first is the Holy Flame circle that spawns under a random player, the second is the Purify beam which the boss calls on to fixate a random player. This beam deals heavy holy damage to anyone who touches it and leaves behind flames, so I recommend tanking the boss on one side of the platform and just having the targeted player kite straight back to conserve space.

There’s also quite a bit of unavoidable group damage going out, mostly through the Inner Fire buff which causes the boss to deal increased holy damage and pulse for AoE damage for 12s. This is especially scary when combined with the Blinding Light cast, which disorients anyone looking at the boss after 4s while also dealing a hit of holy damage to your group. When this cast happens you’ll always want to make sure you turn away from the boss before it ends, and if it ever overlaps with the Inner Fire buff you’ll likely want to pop a group defensives or use a personal as well.

Once the boss reaches 50% health she’ll jump to the upper platform, summon several adds, gain an absorb shield, and start channeling Embrace the Light until that shield is broken and the cast is interrupted. When this happens you’ll want to run to the upper platform as quickly as you can and use damage CDs or Bloodlust to break the shield as quick as possible to stop that heavy pulsing damage.

The adds make this more difficult, as they approach from both sides of the upper platform, meleeing players as well as pulsing for AoE damage thanks to Overwhelming Power. It can be very dangerous to take them on while the boss is channeling, so if you have things like AoE roots, knockbacks, slows, or stuns you can use them on these add groups to make this intermission much safer.

After breaking the shield and interrupting her cast, Murrpray goes back to casting all the same abilities she did at the start of the fight, however now you’re fighting her on the upper platform.
