30min Mythic+ Timer
Every damage number in the spell descriptions below already includes this increase – the same percentage the game shows when you slot the key at the Font of Power.
This is the number from the Font of Power. Tyrannical and Fortified are not included: from +10 both are always active — bosses then hit another 15 % harder, trash 20 %.

At the start of the dungeon you’ll be faced with the choice of moving down the left or right path, where outside of different pack compositions you’ll also face a unique mini boss on either side which will give your group a different buff for the remainder of the dungeon upon defeat.
Going right has more Enthralled Shamans as well as Raj’kess the Spellstorm, who grants players Proof of Mastery on death.
Going left has more Dominated Brawlers along with Aegyra the Unyielding, who instead gives players Proof of Endurance when defeated.
I recommend most groups go left since it requires less interrupts and gives a more generally useful buff.
Assuming you go left, these are the mobs you’ll encounter before entering the arena:
If you opt to go right at the start, you’ll instead encounter the following mobs:
Regardless of which path you take initially, you’ll eventually make your way into the arena which has several new mobs mixed in with some of the previously mentioned ones. After the initial wave is defeated, the mobs spawn in as you pull packs, allowing you to go at whatever pace you choose.
BossTaz'RahdpshealmoveNether Dash does a line attack through each player, loosely spread near the edge of the room to avoid cleaving allies while positioning shades close together, which clumps the Umbral Rupture puddles.
tankhealVoid Blast targets the tank, be ready with a defensive and don’t get knocked into existing puddles.
tankdpshealmoveDark Bloom causes puddles to shoot out multiple orbs that you need to avoid, keep rotating around the room after Umbral Rupture to make these easier to dodge.
This area also splits into two paths, with each side containing a different Lieutenant mob. In general I recommend heading down the right path, especially if your group has access to multiple poison dispels.
If you choose to head down the left side, instead you’ll encounter the following mob:
BossAtroxushealmoveHealers be ready for the AoE damage from Poison Splash and avoid the puddles it spawns as they apply Mind-Numbing Poison to anyone who touches them.
moveNoxious Breath aims a frontal at a random player, stay close to the boss so you can easily avoid it.
tankdpshealkiteDPS be ready to swap to the Toxic Creeper that spawns after Monstrous Roar, as it pulses for AoE damage while alive. This mob just Fixate the tank, who needs to kite as every melee hit applies a stack of Sickening Bite, which makes surviving the Hulking Claw tank buster extremely difficult
After defeating Atroxus, you’ll enter a large open area with many familiar mobs in it. In order to open the arena to Charonus however, you’ll need to kill all three Devouring Brutalizer mobs nearby.
BossCharonushealmoveAvoid getting pulled into any of the Unstable Singularity orbs as they apply Atomized if touched. These pulse for AoE damage while they persist, so healers beware.
Cosmic Crash does an AoE around all players, loosely spread to prevent cleaving your allies.
dpshealkiteGravitic Orbs spawn near DPS players and fixate them, applying stacks of Condensed Mass. Kite them through an Unstable Singularity to destroy them both, using defensives or freedom effects to clear your stacks as needed.
tankhealDark Waves aims a frontal at the tank, use a defensive and point this away from the rest of your group.
moveVoid Cascade shoots out projectiles towards a random player, run away from the boss to give yourself time to dodge, while the rest of your group moves out of their path.
Nothing here matches that filter.
