Tempest Island

VetEasyHMEasy

A Sea Viper stronghold on a storm-wracked island. Three bosses (Valaran Stormcaller, Stormfist, Stormreeve Neidir) and three minibosses. Everything is easy until Neidir, who one-shots careless players on veteran.

01

Valaran Stormcaller

Boss
Tank
  • Hold him still, facing away. Block Crushing Blow (knockback).
  • Grab the Lightning Avatar he summons and keep it on him so it dies to cleave.
DPS
  • Kill the Lightning Avatar quickly (low health).
  • Step aside from the roaming storm and let it pass. Don't run laps.
Healer
  • Break free from Enervating Bolt (stun) promptly; he sometimes targets non-tanks.
👁 Watch for
  • Storm: a huge red circle that drifts back and forth across the arena.
  • Lightning Avatar: a glowing blue-white copy of the boss.
More detail

Squishy Sea Viper spellsword. The giant roaming storm looks scary but is just a big circle to sidestep; the avatar dies fast if stacked on the boss.

02

Stormfist

Boss
☠ Wipe mechanic
  • Below ~20% HP he pulses unavoidable shock damage on everyone until he dies. Save ultimates and burn; healer goes all-in. Running doesn't help.
Tank
  • Hold him in the center facing away. Pick up the three Storm Atronachs fast; they run at the backline.
DPS
  • AoE the atronach adds down on the boss.
  • Step out of the small fist circle (stun) and the big stomp circle (knock-up).
Healer
  • Hold resources for the final enrage phase.
👁 Watch for
  • Skyward Slam: he lifts a foot, a large red circle spreads, then players get launched into the air.
  • Enervating Stone: a fist punches the ground and a stone hand erupts under a player (small circle).
More detail

Giant storm atronach. Simple until the low-health enrage, which is a pure DPS/heal check.

Not fully confirmed:
  • Enrage threshold: UESP says 20%, Xynode says under 25%.
03

Stormreeve Neidir

Final boss
☠ Wipe mechanic
  • Gust of Wind: big red circle spreads under her, then explodes. Get out, stop at the edge, and come straight back in. One-shots non-tanks on vet.
  • Wind Charge: if anyone is far from her, she charges the farthest player for a one-shot. Everyone stays close except during Gust.
  • Lightning Strike: she looks at a player and raises her hand. If it's you, block (and shield). Hurts most at low health.
Tank
  • Keep taunt; she still hits other players at will.
DPS
  • Spread around her, each with your own spot, so you can tell who she is targeting.
  • Watch for twisters before you dodge Gust: one can push you back into the circle.
Healer
  • Focus-heal whoever she's hitting; two hits in a row unhealed can kill.
👁 Watch for
  • Twisters: small whirlwinds roaming the arena; touching one staggers and knocks you around.
  • Gust of Wind: a large red circle growing from her feet.
↯ Alternatives
  • More twisters spawn over time, so long fights get messy. Bring enough DPS to end it quickly.
Hard mode · veteran only

Activate: Veteran only: use the Scroll of Glorious Battle before engaging Neidir (achievement 'Burial at Sea').

  • More health and damage. Same mechanics.
More detail

The real fight of the dungeon. Stay in a loose ring close to her, leave only for Gust of Wind, and come right back. Twisters accumulate, so DPS matters.

Not fully confirmed:
  • Scroll location in the arena isn't described by UESP or Xynode.
  • Xynode calls her light attacks frost and says she fires them in bursts of three at random players; UESP lists a basic shock attack.
