Blackheart Haven

VetEasyHMEasy

Captain Blackheart's pirate island. Three bosses (Atarus, Roost Mother, Captain Blackheart) and three minibosses. Lots of trash; pirate disguises at the start let you sneak past some of it.

01

Iron-Heel

Miniboss
☠ Wipe mechanic
  • Iron Heel kick: a fast spin-kick on a random player with a big knockback. Keep your back to a wall, never to the doorway or the platform edge, or you get kicked off the cliff.
Tank
  • Pull the outside adds into the room and hold him against a wall.
  • Block Crushing Blow (heavy, knockback).
DPS
  • Step out of Berserker Frenzy (red circle spin), then back in.
Healer
    👁 Watch for
    • Argonian pirate. Almost no wind-up on the kick.
    More detail

    Optional, but killing him makes the haven door easier. The only danger is being kicked off the platform outside.

    02

    Atarus

    Boss
    Tank
    • Keep him central and face him away: Projectile Vomit is a green cone.
    DPS
    • Step aside from Tackle, a charge along a red rectangle (knockdown). Regroup after he stops.
    • Step out of Quaking Stomp (red circle) and the stew puddles (snare).
    • Burst near 20%: he grows huge and heals back up (Monstrous Growth). High DPS can kill him before it completes.
    Healer
      👁 Watch for
      • Giant ogrim cook by a stew pot. Drums his chest and glows green = growth phase; afterwards his AoEs are bigger.
      More detail

      Easy if you keep your own space. Expect a second wind when he grows; his AoEs get larger, not stronger.

      Not fully confirmed:
      • Growth threshold: UESP says about 20% HP, healing to about 60%. Xynode says 30% or lower, healing to 50%.
      03

      First Mate Wavecutter

      Miniboss
      ☠ Wipe mechanic
      • Forking Bolt: purple glow in her hands, then a heavy magic bolt at every player. Interrupt it. Missed interrupts can one-shot low-resist players.
      Tank
      • Hold her still; chain in the harpies. Block Crushing Blow (heavy, knockdown).
      DPS
      • Step out of her Whirlwind (small red circle).
      Healer
        👁 Watch for
        • Orc assassin. Purple-glowing hands = interrupt now.
        More detail

        Optional. Easy if someone always interrupts the bolt; a wipe machine if nobody does.

        Not fully confirmed:
        • Xynode calls the bolt 'Shadow Volley' and says it can one-shot. UESP calls it Forking Bolt with 'high' damage.
        04

        Roost Mother

        Boss
        Tank
        • Keep taunt and face her away: Breathe Flame is a big red cone.
        • She teleports often (Daedric Step). Re-grab her each time.
        DPS
        • Never stand in front of her. Raven Storm is a line of flaming ravens with no red indicator.
        • Fiery Sacrifice: she breathes fire upward and ravens land where you were standing. Hold still until the circles appear, then step out. Running scatters the circles everywhere.
        Healer
          👁 Watch for
          • Hagraven in a cloud of crows. Fire breathed into the sky = falling ravens.
          More detail

          Footwork and patience. Regroup behind her after each teleport and don't panic-run during the falling ravens.

          05

          Captain Blackheart

          Final boss
          Tank
          • Tank him where he spawns, your back to the water. Keep chaining in the skeletons he keeps summoning (the ranged ones hug the water).
          DPS
          • AoE the skeletons on him. They have low health but hit hard if left alone.
          • Step out of Cleave (he crouches and spins, red circle).
          Healer
          • If you are the skeleton, nobody gets heals: DPS should slot a self-heal or shield.
          👁 Watch for
          • Skeleton pirate captain from the water. Polymorph Skeleton: he teleports to a player, knocks them down and turns them into a skeleton.
          ↯ Alternatives
          • Werewolf form makes you immune to the skeleton curse (UESP).
          Hard mode · veteran only

          Activate: Veteran only. Read the Scroll of Glorious Battle before engaging him. A full wipe turns it off (achievement 'Thoroughly Plundered').

          • More health and more damage. No new mechanics.
          More detail

          Low-health finale. Every so often a random player becomes a skeleton and can only light or heavy attack (heavy is a damaging breath). If it's the tank, nobody holds aggro: don't run, just block.

          Not fully confirmed:
          • Xynode says the skeleton curse lasts 30 seconds and up to 6 skeletons spawn at a time. UESP gives no numbers.
          • Exact spot of the Scroll of Glorious Battle not confirmed. UESP's general rule: on the floor near the final boss arena.
