Red Petal Bastion

VetChallengingHMHard

Silver Rose knights' fortress full of stolen Daedric artifacts. Three main bosses, each with its own hard mode banner, plus three optional secret bosses in a hidden realm (Goriseli Moraburo) that each give a run-long buff.

01

Wraith of Crows

Secret boss

How to spawn: First secret area, after the first big courtyard. Clear the trash, stand on the glowing circles at the same time to open a portal, enter it and activate the crystal. Two add waves come first, then the boss.

☠ Wipe mechanic
  • Crow Storm: a swirling crow AoE follows one player. Kite it away from the group until it ends. Standing in it kills.
Tank
  • Hold both add waves together and turned away from the group.
DPS
    Healer
      👁 Watch for
      • A skeletal winged figure made of crows, carrying a scythe.
      • Small dark circles pop under each player. Step out or block.
      More detail

      Buff Crystal Animus Agea: +10% Max Magicka and Stamina. Healing a hurt ally summons a spirit that attacks a nearby enemy (up to three).

      Not fully confirmed:
      • Exact location of the circles. One guide only says 'the first main area'.
      02

      Rogerain the Sly

      Boss
      ☠ Wipe mechanic
      • Unspeakable Void: a big dark pool on the floor that sprays purple orbs outward. Get out of the pool and sidestep the orbs.
      • Heavy attack: tank blocks. If anyone else has aggro, dodge-roll.
      Tank
      • Park him in one spot, ideally mid-room. Keep the adds stacked on him.
      • Don't drop taunt. The goat is usually not the tank, but a lost taunt can put it on you.
      DPS
      • Priority: Chaos Gate (portal) first, then all adds, then the boss. Every portal left alive keeps spawning spiders, frogs and watchers.
      • Kill the Death Hoppers (frogs) fast. They're squishy and can be CC'd.
      Healer
      • If you get turned into the goat, your group has no heals. Pre-shield and pre-HoT before goat casts.
      👁 Watch for
      • Goat: one player is grabbed and turned into a goat. Golden sweetrolls scatter around the room; the goat runs over them.
      • Poison blobs arc across the room. Ones aimed at a player grow, then pop. Don't stack them.
      • Crazed Leap: he slams his greatsword; four swirls fly outward with no telegraph.
      ↯ Alternatives
      • Goat: charge the portal as the goat. It does big damage to it.
      Hard mode · veteran only

      Activate: Banner before the boss (veteran).

      • More HP and damage. No new mechanics (two guides agree).
      More detail

      He swaps between dagger, greatsword and ranged attacks. The goat's sweetrolls give the group buffs and heals, so it isn't purely bad.

      Not fully confirmed:
      • Goat duration: UESP says you must eat ten sweetrolls to turn back. Xynode says it ends on a timer.
      03

      Spider Daedra

      Secret boss

      How to spawn: In the Artificer's House area. Clear the house, then stand on its magic circles at the same time (one guide says one each on the basement, main floor and top floor). Enter the portal and activate the crystal. Two add waves, then the boss.

      Easy fight. Block the heavy.

      Tank
        DPS
        • Spit: the boss spits at one player. Stay spread so you can see who; the target dodge-rolls.
        Healer
          👁 Watch for
          • Lightning: two players at a time get a lightning strike. Dodge or block.
          More detail

          Buff Crystal Animus Anya: +10% Max Health. Blocking spawns flames in front of you that grow stronger the more attacks you block.

          04

          The Artifact Bearers

          Boss
          ☠ Wipe mechanic
          • Stay near Eliam. Anyone far away gets a leap (Stonesplitter Plunge) on their head that can one-shot. Dodge it if it comes.
          • Charge: he charges the tank with his shield up. Block or dodge; non-tanks get one-shot.
          • Don't stand in the lightning AoEs on the floor. They kill fast, even tanks.
          Tank
          • Face Eliam at a wall, away from the group. Heinous Highkick knocks you back even through block, so be ready for the next hit.
          • Taunt every add. On HM, hold both adds in execute because they can't be killed then.
          DPS
          • Kill Liramindrel (archer) as soon as she spawns. Ihudir (melee) teleports and channels: interrupt him.
          • Interrupt from range if you need to, but don't spread far or Eliam leaps.
          Healer
            👁 Watch for
            • Eliam: big knight with golden boots. Golden Stomp is a big growing circle that leaves lingering magic.
            • Liramindrel: a High Elf archer. Wide arrow cone, and arrows that crack the floor into small damaging circles.
            ↯ Alternatives
            • Kill the adds by stacking them on Eliam. They get back up after a while.
            Hard mode · veteran only

            Activate: Banner before the boss (veteran). You must have killed Rogerain on HM first.

            • Liramindrel shields Eliam while she's alive (he takes much less damage). Kill her first, every time.
            • Ihudir empowers Eliam while he's up.
            • Execute: the returning adds can't be killed (they out-heal you). Tank holds them; burn Eliam.
            More detail

            Liramindrel joins around 80%, Ihudir around 50%. Around 30–35%, Eliam brings both back to full health if they're dead.

            Achievement 'Foolhardy Footwork' needs 40 traps triggered in one fight, so don't do that on a normal run.

            Not fully confirmed:
            • Add timings (80% / 50% / ~30%) come from guides. UESP gives the resurrection at 35% and doesn't give the join percentages.
            • That the execute adds are unkillable on HM comes from one guide (Xynode, which says this changed after PTS).
            05

            Grievous Twilight

            Secret boss

            How to spawn: Third secret area, before the final boss. Clear the trash, stand on the circles at the same time, enter the portal and activate the crystal. Two add waves, then the boss.

            ☠ Wipe mechanic
            • Meteors: one lands on each player. Stay spread; block or dodge yours.

            Easy fight. Don't stack.

            Tank
            • Machine gun: it fires a stream of energy balls at one player. Stand in the stream and block it for them. The target stays still.
            DPS
              Healer
                👁 Watch for
                • A winged twilight that teleports. Works like Lord Warden Dusk in Imperial City Prison.
                More detail

                Buff Crystal Animus Nagaia: +10% Weapon and Spell Critical. Heavy attacks plant explosives that detonate together for extra damage.

                Not fully confirmed:
                • Exact location of the third set of circles. Guides only show it on a map image.
                06

                Prior Thierric Sarazen

                Final boss
                ☠ Wipe mechanic
                • Opalescent Impale: he teleports to a corner and a red marker appears under one player. Interrupt him or that player dies to a one-shot.
                • Blade Projection: he stabs his sword into the floor and AoEs pop under every player several times. Keep walking in a small circle; don't overlap with others.
                • Cleave: wide frontal cone after the kick. Only the tank stands in front.
                • Shield walls sweep across the room (from about mid-fight). Find the gap. Getting hit stuns you, and a stunned tank dies to the kick.
                Tank
                • Hold him in the middle, standing still. From there you see the walls coming.
                • Heinous Highkick knocks you back through block. Be ready for the cleave right after.
                • Taunt every Realmshaper and stack them on the boss.
                DPS
                • Kill adds first. There's no DPS check. Interrupt the Realmshapers' channels.
                • Someone with a ranged interrupt watches for Impale every time.
                Healer
                • Healing circles he casts heal him and hurt you. Get out, and tell the tank to pull him out.
                👁 Watch for
                • Impale: he vanishes to a corner and channels; the target has a red circle under their feet.
                • Walls: rows of glowing magical shields sliding across the floor, with gaps.
                • Blade Tempest: at low health, big slow-moving red whirlwinds spread out. Walk around them.
                Hard mode · veteran only

                Activate: Banner before the boss (veteran). You must have killed Rogerain and the Artifact Bearers on HM first.

                • Impale: he's inside a shield bubble. Ranged interrupts don't work. Run into the bubble and interrupt in melee. Bring a gap-closer.
                • Walls cover a whole side of the room (one guide), or extra stun orbs appear (another).
                • Blade Projection blades will likely kill a non-tank.
                More detail

                He wields all three artifacts, so he uses Eliam's kick and Golden Stomp, plus new moves. At about 75% he runs to the middle and charges. Adds come in waves with long gaps, so you'll get quiet periods on just the boss.

                Not fully confirmed:
                • HM wall change: Xynode says a full side of the room; Deltia says more stun orbs on the ground. Treat walls as much denser on HM.
                • Healing circles are only mentioned by Xynode.
