Plaguefall, Healer Guide

Updated 9 months, 3 weeks ago for patch 9.1.0 by Preston. View the change log.

This page covers healer-focused strategies for the Plaguefall dungeon in Shadowlands. While it's tailored for healers, other roles may also find the information useful. If you have any suggestions or feedback, you can leave a comment below or tweet @PrestonDvorak.

This guide has been updated and maintained based on my own experiences as well as Dungeon Journal and combat log information. I'll continue to update it as-needed.


Below are guides for the bosses in Plaguefall, including their abilities, healer notes, and addon settings.

Globgrog Dungeon Journal Model Globgrog

  • During Beckon Slime, all Slimy Morsels and Slimy Smorgasbords must be killed before reaching Globgrog to prevent the healing from Consume Slime.
  • Deals light damage to and knocks back all players with Plaguestomp.
    • Additionally, applies Debilitating Plague (dispel, disease) to all players, reducing movement speed and dealing light damage over time.
  • Don't stand in front of the boss when it turns to cast Slime Wave.
    • Players hit take moderate damage over time from Slime Wave.

 Healing Notes

  • If the boss is allowed to heal, this fight can become quite long, but the healing requirement shouldn't be too high beyond that.
 Debuffs to Track

Doctor Ickus Dungeon Journal Model Doctor Ickus

  • Before engaging the boss, be sure all of the landmasses among the slime lake are clear as the boss will periodically jump to different areas, detailed below.
  • The tank will be dealing with Slime Injection (dispel, magic).
    • When dispelled, each stack of Slime Injection (dispel, magic) spawns a Slithering Ooze.
      • Slithering Ooze
        • Stepping on an Ooze kills it while dealing light damage to the player with Bursting Ooze.
        • Must be killed before their Erupt cast finishes and deals moderate damage to all players.
  • Avoid the impact location of Slime Lunge, targeted on the player furthest from Ickus.
  • Periodically jumps to a Plague Cauldron and manifests a Plague Bomb slime that must be killed before its Virulent Explosion cast finishes and deals fatal damage to all players.
  • Pestilence Surge summons several Pestilence Slimes, and on Mythic, Congealed Slimes.
    • Pestilence Slime
      • Target random players with Viral Globs, dealing light damage.
      • When killed, leaves behind a Rapid Infection pool that grants haste and deals light damage over time while standing in it.
    • On Mythic, Congealed Slime
  • If no players are in melee range, Burning Strain deals moderate damage to random players and increasing damage over time.

 Healing Notes

  • Be aware of how many stacks of Slime Injection (dispel, magic) the tank has and dispel it before they get too high to keep the resulting Slithering Oozes from getting out of control.
 Debuffs to Track

Domina Venomblade Dungeon Journal Model Domina Venomblade

  • The tank will be dealing with Cytotoxic Slash (dispel, poison), taking extra damage from Venomblades while active.
  • When affected by Shadow Ambush, move at least 10-yards away from other players.
  • Brood Assassins are periodically called to join the encounter.

  • On Mythic, stay within 6-yards of at least one other player to avoid the Web Wrap from Solitary Prey.
    • Web Wraps must be killed to free the affected player.

 Healing Notes

  • Use cooldowns as-needed while Brood Assassins are hitting players with Assassinate.
