Scalecaller Peak

VetChallengingHMVery hard

Snowy mountain shrine of a dragon cult. Five bosses, ending with Zaan the Scalecaller, where cone-breathing statues and a shield mechanic punish bad positioning.

01

Orzun the Foul-Smelling and Rinaerus the Rancid

Boss
☠ Wipe mechanic
  • Ice storm (Rinaerus channel): hide behind an ice pillar or you freeze.
  • Snow tremor targets you (on-screen message): use the freeze spot (ice spike / circle) so the tremor doesn't kill you.
  • Orzun's heavy one-shots non-tanks. Tank blocks; others roll.
Tank
  • Taunt both. Keep the ogre away from the caster.
DPS
  • Interrupt Rinaerus's channel or skeevers spawn.
  • Kill them close together. The survivor enrages after the other dies.
Healer
    More detail
    Not fully confirmed:
    • Tactic: Xynode says tank both together; Fextralife says kite Orzun and kill Rinaerus first.
    • Freeze spot: Fextralife says yellow circles from Rinaerus; Xynode says a moving ice spike.
    02

    Doylemish Ironheart

    Boss
    ☠ Wipe mechanic
    • Red spheres chase one player and petrify on contact. Kill them; don't run far.
    • Free petrified players immediately, or he channels a one-shot (interruptible, but he enrages).
    Tank
    • Hold him still facing the door. Block heavies.
    DPS
    • Spheres at 80 / 60 / 40 / 20%. Focus them, then AoE the Ice Wraiths.
    Healer
    • Cleanse/heal the tank's bleed.
    👁 Watch for
    • A small pulsing AoE under a player marks the sphere's target. Lasers petrify too.

    03

    Matriarch Aldis

    Boss
    ☠ Wipe mechanic
    • Icy water around the arena freezes and kills. Stay out.
    • Plug the ice: during her channel, a small ice spike appears. Tank stands on it or the group takes huge damage.
    Tank
    • Hold her in the middle. Don't wander off to taunt adds; she leaps to you and quakes the group.
    DPS
    • Leimenid adds spawn about every 10%. Kill them fast or they make geysers.
    • Don't overburn: she has low HP and adds stack up.
    Healer
      👁 Watch for
      • She fears the group sometimes. Break free and keep moving.
      ↯ Alternatives
      • Move back out of her stomp unless shielded.

      Plague Concocter Mortieu

      Boss
      ☠ Wipe mechanic
      • Interrupt 'Take Aim' (big single-target shot). It can one-shot a DPS/healer.
      • Poison grills: the tank stands on the active grill and blocks, or poison hits the group.
      • Guard heavy: one-shots without block.
      Tank
      • Hold him in the middle; return after each grill block.
      • Pull the guard to the boss during the potion stun.
      DPS
      • Potion phase: kill adds in order Imps, Stranglers, Beetles (Jorvuld calls what he needs).
      • Stand together in the positive AoE afterward for the buff.
      Healer
        👁 Watch for
        • Arrow spray cone; a spreading fire AoE that sends out four fire lines. Step aside.
        More detail

        Poison stacks on the group in tiers. Making the antidote cleanses it and stuns the boss.

        05

        Zaan the Scalecaller

        Final boss
        ☠ Wipe mechanic
        • Poison breath statues: three dragon heads at the back. The one that glows breathes a cone that one-shots. Block and roll don't work. Stand on the border between two cones and sidestep.
        • Poison storm: stand in Zaan's shield when it drops. When she yells 'MY SHIELD', get out.
        • Ice phase every 20% (80/60/40/20%): she's immune and ice statues spawn. Kill them fast; the group takes heavy ice damage.
        Tank
        • Hold her still, away from the group, no spinning.
        • Take the Flame Beam: block it for whoever she targets.
        DPS
        • Kill the Leimenid and Frost Atronach adds while stacked on the boss.
        • Scan for ice adds near the statues at each 20%.
        Healer
        • Heavy HoTs during the ice phase. Rez right after it ends.
        👁 Watch for
        • Ice trails on the floor point to where ice adds will spawn.
        • Fire Breath: a constant flame wave following one target. Flame Beam: a beam held on one player.
        ↯ Alternatives
        • Fire breath follows you (red circle + message): run a wide circle, or block behind a pillar.
        Hard mode · veteran only

        Activate: Read Zaan's Ritual Scroll before the fight (veteran only).

        • Only one player can use Zaan's shield. Everyone else needs a different safe spot: atronach ice, Leimenid geyser, or the petrify laser. Assign one per player before the storm.
        • Safe spots expire quickly. Be in place on time.
        • More HP.
        More detail

        Line up between the middle and right statues so one step dodges any cone. The dead Atronach leaves moving ice and the dead Leimenid leaves a geyser. Both stun you, and on HM they become poison-storm safety spots.

        Not fully confirmed:
        • A 2018 forum report says freeing someone from the petrify beam can override the shield synergy. May be fixed.
        • Whether the tank also needs a safe spot on HM. A 2018 forum guide says the healer takes the shield and the tank has no ice-phase task.
