City of Ash I

VetEasyHMEasy

A Bosmer grove-city overrun by Dagonite cultists and fire Daedra. Three bosses (Infernal Guardian, Warden of the Shrine, Razor Master Erthas) and three minibosses. Hard mode is the Scroll of Glorious Battle on Erthas.

01

Infernal Guardian

Boss

Mostly tank and spank. Stay behind it.

Tank
  • Face it away from the group; block its two-hit slam.
DPS
  • Stay behind it: Fiery Explosion sprays fire in front. Step back from its body while it's burning.
  • Don't stand far away: Tunneling Roots hits distant players and knocks them down.
Healer
    👁 Watch for
    • Flaming lurcher (tree creature). Red circles fanning out in front = Fiery Explosion.
    More detail

    Opening boss. Everything nasty hits the front or players far away, so stand behind it at melee range.

    02

    Warden of the Shrine

    Boss
    Tank
    • Keep him on his starting platform, facing away; block Measured Uppercut (big knockback).
    DPS
    • Don't stand far from him: Teleport Strike hits and stuns the farthest player. Block if that's you.
    • Blazing Fire: step out of the fire ring. If the circles spawn further out, the middle next to him is safe.
    Healer
      👁 Watch for
      • Dremora nightblade, dual wield, on a small raised platform. After he spins, a ring of fire pools appears around him.
      More detail

      Small elevated arena. Block the heavy, avoid the fire ring, and don't run off or he teleports to you.

      Not fully confirmed:
      • Xynode warns his unblocked heavy can fling non-tanks to their death; UESP says high damage and knockback.
      03

      Razor Master Erthas

      Final boss
      ☠ Wipe mechanic
      • Blazing Arrow: a flaming arrow that leaves a long, heavy fire DoT that can't be purged. Jump into the water between the islands to put it out.
      • Lava Pitch: a fireball that splits into four fire lines (a cross). Stay out of the lines.
      Tank
      • Have a ranged taunt for the flame atronachs he summons.
      DPS
      • Kill atronachs as they come. Near the end he summons several at once: stack and AoE them, or burn him.
      • He teleports between islands: follow, and drop ultimates just after he lands.
      Healer
        👁 Watch for
        • Bosmer archer on small islands with water between them. A player 'on fire' for a long time = go swim.
        • 'Rise, minion!' = flame atronach incoming.
        Hard mode · veteran only

        Activate: Veteran only. Read the Scroll of Glorious Battle on the left side of the arena before Erthas comes out of the portal (achievement 'Fire Brigade').

        • Erthas gets more health and deals more damage. No new mechanics.
        More detail

        Ranged boss who hops between islands. Follow him, kill his atronachs, avoid the fire cross, and cleanse Blazing Arrow in the water.

        Not fully confirmed:
        • Final add burst: UESP says 4 atronachs at about 20%; Xynode says 3 at 25%.
