Lep Seclusa

VetHardHMVery hard

An island fortress of deserters and war beasts. Three main bosses (Garvin, Noriwen, Orpheon), each with its own hard mode, plus three minibosses. Vet is widely considered one of the hardest 4-player dungeons.

01

Lewin Frey

Miniboss
☠ Wipe mechanic
  • Shocking Split: two lightning clones teleport around the arena dropping stunning AoEs. You can't roll or break free from the stun, so keep out of their path.
Tank
  • Face him away. His light attacks cleave in front.
  • If you're far away he teleports onto you with a blockable AoE (Thunder Thrall). Block it.
DPS
  • Conduit: he teleports and drops an AoE on a random player that also hits anyone nearby. Don't stack.
  • Overcharge: a knockback blast around him, then he takes less damage for a while. Block, roll or step away.

    Garvin the Tracker

    Boss
    ☠ Wipe mechanic
    • Venom Eruption: after a 3s warning, massive damage over 6s to anyone in his line of sight. Hide behind a rock.
    • Ricochet (vet): two players get linked. When it ends, break line of sight with your partner (put a rock between you). Otherwise you take huge damage, or die outright on the short version.
    • At 30% he screams, fears everyone and enrages every Monstrous Duneripper still alive. Have them dead before 30%.
    Tank
    • Aim his Noxious Boulder (stunning projectile toward you) into a Duneripper. It one-shots an unenraged one. With no Duneripper up, aim it away from the group.
    • Don't pull the Dunerippers; they stay idle until engaged. Kill each one before the next spawns.
    • Keep him facing you. Piercing Dervish cones you and the opposite side, and it follows you if you sidestep.
    • Block Whirlwind (heavy). On vet it adds a healing absorb.
    DPS
    • Stand to his sides, never behind him (Piercing Dervish).
    • Interrupt the Infusers. They heal and enrage all adds and Garvin, and shield other adds.
    • Slow down after 40% so the 40% Duneripper can be bouldered before he hits 30%.
    Healer
    • Wild Spores: an 8s group DoT that hits hard. Heal through it.
    👁 Watch for
    • Dunerippers: big burrowing beasts that spawn at about 80%, 70%, 50% and 40%.
    • Vanishing Powder: he poofs to a corner and lays traps. Don't bother interrupting; just avoid the traps.
    • Adds: storm mages (electrify water), flame archers (cones and volleys) and Infusers (healers).
    Hard mode · veteran only

    Activate: Banner before the boss (veteran).

    • More HP (about 1.5x vet).
    More detail
    Not fully confirmed:
    • HM changes: Hyperioxes lists only higher HP. No source lists new HM mechanics.
    • Duneripper and add spawn percentages come from Hyperioxes only. ArzyeL (older, likely PTS-era) gives different trap-phase percentages.
    03

    Siege Master Malthoras

    Miniboss

    How to spawn: Optional. He shoots from siege engines on high ground. Fetch Ballista Parts, repair the ballistas, and shoot down his four siege weapons to force him to the ground.

    ☠ Wipe mechanic
    • True Shot: long channel, then a huge arrow at one player. Interrupt it or roll.
    Tank
    • Block Quakeshot (three bouncing projectiles at you) and keep his frontal cone off the group.
    DPS
    • At 50% he blows a horn and calls scouts. Kill them.
    • Keep moving out of Volley and Fire Bomb AoEs. Leave Shattering Stomp (stagger) around him.
    Healer
      More detail

      If you skip him, his siege seems to keep firing on later fights. 'Siege Suppressor' asks you to destroy 10 of his siege engines.

      Not fully confirmed:
      • Whether he's the skippable one: ArzyeL says he's the only skippable boss. Hyperioxes says two of the three minibosses are skippable but doesn't name them.
      • A 2025 forum thread reports him healing back to 100% (likely a bug or a reset).
      04

      Noriwen

      Boss
      ☠ Wipe mechanic
      • Flame Gryphons (50%): she leaves and two Flame Gryphons fight you (up to ~80s or until both die). Their Fiery Cyclone at the tank can kill DPS and healers. Stay out of their AoEs and kill them fast.
      • Chain Pull: if the tank is out of melee range she drags them in and applies a massive purgeable DoT. Tank: stay in melee. Healer: purge it.
      Tank
      • Block Brand (heavy). Dodge-rolling it enrages her.
      • She jumps and charges around. Follow her and walk her back toward the center.
      • At 70% and 20% she charges to the big gryphon Alcunar and stays there. Drag her near Alcunar before those thresholds so you don't eat Chain Pull. Block Alcunar's pecks.
      DPS
      • At 40% two more Flame Gryphons spawn alongside her. Focus them.
      • Move out of Blast Powder (fire AoEs on a random non-tank).
      Healer
        👁 Watch for
        • Wing Gust: Alcunar sends three lightning tornadoes across the arena. Touching one gives a DoT. Avoid them.
        • Gryphon Bombers dive through the arena and stagger whoever they hit unless blocked. They can't be killed. From 50% some drop fire bombs (fire line).
        Hard mode · veteran only

        Activate: Banner before the boss (veteran). Garvin must have been killed on HM.

        • More HP (about 1.6x vet).
        • Wing Gust DoT also damages players around you. Spread if you get hit.
        More detail
        Not fully confirmed:
        • Chain Pull is described from Hyperioxes. ArzyeL (older) describes a fire-bomb pull-in instead.
        • Interaction with Malthoras's siege if he was skipped (see notes).
        05

        Flamedancer Ajim-Rei

        Miniboss
        ☠ Wipe mechanic
        • Imminent Eruption: she teleports and channels a big AoE. Interrupt it. If you miss, everyone needs to be at full HP.
        Tank
        • Block Incinerating Prance (heavy). On vet it adds a healing absorb.
        DPS
        • Firestorm Waltz: a fiery clone channels fireballs at random players. Interrupt it.
        • Kill the Blazing Shalks. They leave burning ground.
        • Heat Wave: an untargetable clone casts a cone at a random player. Turn so it doesn't hit the group.
        Healer
          👁 Watch for
          • Sweeping Firestarter: three fire lines toward a random player. The DoT also splashes on players near them.

          Orpheon the Tactician

          Final boss
          ☠ Wipe mechanic
          • Arcane Planemeld: a green restricted zone covers most of the arena and does ramping damage. Stay in the safe area. It shifts at 80%, 50% and 30%, then keeps moving after 20%.
          • Forbidden Knowledge: unblockable runeblades fire at everyone. Dodge-roll.
          • Reality Fracture (heavy, 2.4s windup, can't be rolled): an AoE around the tank. Everyone else stays away from the tank.
          Tank
          • Never let Orpheon stand in the Planemeld. He goes untargetable there and can cast Forbidden Knowledge. Drag him with the safe area as it moves.
          • Stay away from the group and block his cleave. Unblocked hits drain your Stamina and Magicka (Slow Descent).
          • In add phases, block the big add (Arcane Hulk or Wraith) and chain the small adds.
          DPS
          • Add phases (80%, 50%, 30%): he teleports into the Planemeld and summons a big add plus three small ones. Kill them to bring him back.
          • Abyssal Conjuration: tentacles spawn at two players. Block the knockback and kill the tentacles.
          Healer
          • During add phases Alcunar attacks from the side and Orpheon fires projectiles. Heal through it.
          👁 Watch for
          • Planemeld: a shadowy green field. Inside it, tentacles attack and lightning tornadoes (Wing Gust) roam.
          • Alcunar (Noriwen's gryphon) joins during add phases and for the final 20%. It can't be targeted.
          • Arcane Void: a big add's AoE. Block it.
          Hard mode · veteran only

          Activate: Banner before the boss (veteran). Garvin and Noriwen must have been killed on HM first.

          • More HP (about 1.6x vet).
          • Smaller safe area in the Planemeld.
          • Unblocked cleave drains more Stamina and Magicka.
          • Wing Gust DoT also damages players around you.
          More detail
          Not fully confirmed:
          • Add-phase thresholds and safe-area movement are from Hyperioxes only. ArzyeL (older) agrees on 80/50/30 add phases.
