Floating Ayleid archive of the Celestial Mage in Craglorn. Four bosses, linked by teleport-pad sections that split the group into three teams of four.

☠ Wipe mechanic
  • Overchargers: kill first. They put a large red AoE on a random player that moves with them. That player stays away from the group.
  • Frost room: frost whirlwinds stun you if you cast while running through. Just move.
Tank
  • Turn Frost Atronachs away (frontal cleave).
DPS
  • Priority: Overchargers > Chainspinners > Nullifiers. Interrupt Nullifier Healing Links.
Healer
    👁 Watch for
    • Overcharger: lightning caster. Its target gets a big red circle that follows them; standing still also spawns small red circles.

    Lightning Storm Atronach

    Boss
    ☠ Wipe mechanic
    • Lightning Storm: when he raises his hands, one of five faint circles lights up yellow. All 12 get into it and stay until the storm ends, or die.
    • Impending Storm: a spreading AoE under him that explodes at full size. Block it (magicka: shield). Unblocked players usually die to the small follow-up strikes.

    Block Impending Storm, run into the lit circle for Lightning Storm, and stay stacked on him otherwise.

    Tank
    • Hold him in the middle, facing away. His punches can one-shot DPS, so keep taunt.
    DPS
      Healer
      • Shields and HoTs ready for the run to the safe circle.
      👁 Watch for
      • Safe zone: a large yellow beam of light on one of five floor circles.
      More detail

      Name the 5 circles before the pull (e.g. front, back, left, right, top-right) and have someone call the lit one.

      Not fully confirmed:
      • High DPS likely kills him after only one or two Lightning Storms. No source gives a number.
      03

      Foundation Stone Atronach

      Boss
      ☠ Wipe mechanic
      • Boulder Storm (75% and below): when he crouches, rocks launch at players. Spread out a bit and hold block; don't move. Restack when he stands.

      OT parks each Chainspinner/Nullifier pair on the boss so they die in the cleave. Spread and block only while he crouches.

      Tank
      • Turn him away from the group. His hitbox is awkward; keep him targeted.
      • OT: park the adds where the MT's cleave hits them.
      DPS
      • Adds come in pairs: Chainspinner (stuns, AoE circles) and Nullifier (heals; interrupt it).
      Healer
      • Big Quake: 5 ground pounds in a row hit everyone. Keep the group stacked and heal through.
      👁 Watch for
      • Crouching stone atronach = rock phase. Floating boulders fly at players.
      More detail
      Not fully confirmed:
      • Add priority: Xynode says Chainspinner first; eso-mechanics says Nullifier first. Either works if you interrupt the heal.

      Varlariel

      Boss
      ☠ Wipe mechanic
      • Clones: she splits into ghosts that run to the pillars (3 at first, +1 each split, max 6). Live ones explode after a delay; more alive = bigger blast. Kill them all, or at most leave one and block.
      • Rain of Wisps: red circles under random players that grow and explode. One hit is survivable, two kills. Don't stack.
      • Frozen Breath: frontal cone. Only the tank stands in front.

      DPS check 36k Vet per DPS · Kill before 6 clones
      • Skip the later clone waves: kill her before she reaches six clones.

      Kill every clone but the agreed one and block its blast.

      Tank
      • Keep taunt: her magic bolts on a DPS can kill. OT taunts and debuffs clones.
      DPS
      • Two DPS per pillar, preassigned. The clone headed to the lit or mushroom pillar is the one usually left alive.
      Healer
      • Burst heals and shields for the clone explosion.
      👁 Watch for
      • Clone phase: ghostly copies drift to the pillars; light beams signal the explosion.
      More detail
      Not fully confirmed:
      • High DPS may kill her before the later clone waves (5–6 clones). Likely, but no current source says how often.
      • Which clone to skip: Xynode says the reddish-orange mushroom pillar; Fextralife says the green-light pillar; eso-mechanics names both. Agree before the pull.

      The Mage

      Final boss
      ☠ Wipe mechanic
      • Chain Lightning: hits players in her front 180° and jumps to anyone within ~8m, growing stronger. Nobody but tanks crosses the center line; keep a gap between tank and group.
      • Black Holes grow at the platform edges. Stay out; they're near-instant death.
      • Conjured Reflections: a fast-spreading AoE, then a reflection appears. Kill it fast (room-wide damage). Don't cross the line to reach it.
      • Execute (15%): three knockdowns, then a nova creeps toward the group, hitting harder over time. Kill leftover Reflections before pushing her under 15%.

      Hold positions. Clear leftover Reflections, then nuke through the 15% execute.

      Tank
      • MT: taunt from max melee range, facing the entrance. Group stacks behind her.
      • OT: grab the Conjured Axes right away (block their heavy) and park them by the entrance. Don't kill them.
      DPS
      • Kill Reflections from range on the tank's side.
      Healer
      • Execute: stagger group buffs and big heals. Shield to walk into a problem mine.
      👁 Watch for
      • Axes: large purple floating axes, cued by her line 'I cannot control my armory'.
      • Mines: small glowing traps that stay until someone triggers them.
      ↯ Alternatives
      • High DPS: mostly ignore the Mines: shield up and walk into one if it's in the way.
      Hard mode · veteran only

      Activate: Smash the three Aetherial Orbs on the portal platform before her room (vet only).

      • More health and harder hits; she regains some health during the execute knockdowns.
      • Storm Atronachs spawn periodically. MT pulls them to the boss and the group kills them before they get low: their Unstable Explosion / meltdown spams lightning on everyone.
      • Meteors on random players: block to avoid the knockdown.
      More detail
      Not fully confirmed:
      • HM Storm Atronachs: high-DPS groups probably just cleave them down on the boss. Likely, but unconfirmed.
      • Fextralife says the orbs are 'near the front transport pads' after Varlariel; UESP and eso-mechanics say beyond the last set of pads before the Mage. Same spot, phrased differently.
