Disclaimer: This guide assumes you know and understand how to defeat the heroic encounter, and as such will not be talking about basics of the boss itself. This is intended to teach you the differences between heroic and Mythic, and how to defeat the Mythic version. If you need a refresher on the basics of the encounter, please visit our heroic guide. 

Mythic Changes

  • New add, Mawsworn Overlord
    • Larger versions of the regular adds
    • Has a circle around him. Any other adds within the circle are buffed with Defiance, making them immune to crowd control and deal 200% increased damage
      • Important note here – this does NOT REMOVE existing crowd control. It only prevents NEW crowd control
    • This add cannot be gripped or knocked back, must just be burned down
    • Additionally, if the Overlord reaches Garrosh, it grants Defiance to ALL Agonizer adds, super bad news bears
  • Torment hurts a lot more, you just die now
  • Warmonger Shackles hurt a shitload more now too, need to plan out timing of popping them
    • Hellscream is only a 25 second cast on Mythic. If a tick goes off, you’ll wipe
  • Echoing Screams got buffed, passive 4k shadow every 2 seconds to the raid
  • Ruinblade forces tank swap each cast now

Strategy

  • The primary bits of difficulty here are dealing with the adds properly, and the Warmonger Shackles. Both require a good deal of coordination.
  • Comp – 2 tanks, 5 healers, 13 DPS
  • Bloodlust on pull
  • Tanks need to swap after each Ruinblade
  • Adds
    • You’ll want to have multiple players with knockbacks and/or grips in your raid
    • As soon as the adds spawn, isolate the Overlord
      • Use those knockbacks or grips to move smaller adds away from the Overlord
      • Stack up the Agonizers, away from the Overlord
      • Stack your Brands of Torment on the Overlord, and blow it up as fast as possible

      • As soon as the Overlord dies, everyone should swap and annihilate the Agonizers
        • Bring the Brands of Torment on top of the Agonizers for the damage buff
        • You may get a Torment while you’re trying to kill adds. Keep them slowed / CC’d if this happens
    • Make sure you always have slows applied to the Agonizers
    • Utilize Brands of Torment to their fullest. Always double stack these on whatever you’re killing – the extra damage is incredibly powerful
    • As a note – you CAN hard-CC the Agonizers. Freezing Trap, Imprison, etc will work. Doing this is better than just a slow, so hard-CC them when possible 
      • You can see this in the gif above
  • Warmonger Shackles
    • Assign groups of 3 for this before you pull. You can NOT do this twice during the same fight. 
      • Plan for 6 sets of Shackles, meaning 18 people need to yoink chains
      • Assign every player except your 2 tanks
      • In your assignments, specify which shackle each player is doing – left, center, right
    • When these come out, everyone in the raid should stack near the center of the room
    • Drop a Warlock’s Gateway from the middle Shackle, to the back of the room
    • The assigned 3 person team should all click their Shackles, and wait for the RL to call out
    • Have these people click the gateway, which’ll shoot them to the back of the room & break their Shackle
      • Raid Leader calls out which player goes when. Ensure there’s enough time between breaks for the healers to stabilize the raid

    • Pop DR cooldowns during this. Barrier, AMZ, Devo, etc. This’ll help keep the raid healthy
    • Get through all 3 Shackles as quickly as possible, because if Hellscream gets a tick off, you wipe
  • The real pain in the ass is that you can have Shackles overlap with adds
    • When this happens, obviously still kill the adds, but prioritize getting Shackles done ASAP
    • You can survive being slow on adds, you cannot survive being slow on a Shackle
    • This overlap always happens at 4:20. See GIF below for example

  • Aside from that, don’t mess up heroic mechanics. Dodge swirlies, dodge Torment, survive the dance, etc.
