Naj-Caldeesh

VetHardHMVery hard

A corrupted Argonian xanmeer overrun by Talen-Lah's necromancers. Three bosses, each with its own hard mode, plus three optional rhythm puzzles (vossa-saxtl) that give group buffs. Newer content with thin guide coverage, so check the unconfirmed notes.

01

Vossa-saxtl songs (3 rooms)

Optional puzzle

Where: Three optional side rooms, one per map, marked on the map: Hidden Entrance, Ritual Quarters and Keystone Chamber. Rooms 1 and 3 open when two players stand on pressure plates. Room 2's entrance is open but easy to miss.

✦ Solution
  1. Everyone stands on a Pedal Pad around the vossa-saxtl (a stone organ).
  2. Stomp your pad when the sound wave reaches the wall (the green mark).
  3. Keep going until the song ends. Each room plays the same song.
  4. Do all three rooms for the buffs and the 'Temple Hero' achievement.

        Buffs: Strength of the Ancients (weapon and spell damage), Stone-Stored Energies (Magicka and Stamina recovery), Borrowed Vitality (max health and less damage taken). 'Rhythmic Genius' needs only perfect stomps.

        Not fully confirmed:
        • Whether each room gives one buff or all three come after the third room. ArzyeL lists them as unlocked by completing all three.
        • A PTS post says the rooms need four players. Not confirmed on live.
        02

        Poxito

        Boss
        ☠ Wipe mechanic
        • Bone Effigies (totems) spawn at HP thresholds. Later she draws on them for a big burst; every living totem makes it hit harder. On HM, kill all of them before the burst.
        • Don't push the boss too fast. If totems pile up, the burst wipes the group.
        Tank
        • Face her frontal cone away from the group.
        • Pull her onto the saw blade trap to strip her Bone Armor (her invulnerability shield).
        DPS
        • Kill totems as soon as they spawn. Ignore other adds while you do.
        Healer
        • Ghosts (Haunting Specters) come from the totems. If one reaches you, you get feared or possessed. Break free fast, and don't run onto the fire-trap plates.
        👁 Watch for
        • Bone Effigies: bone totems that pulse AoE damage and release ghosts.
        • When she dies she turns into a phantom skull and flies off to the next area.
        Hard mode · veteran only

        Activate: Banner before the boss (veteran).

        • More HP.
        • Even one or two living totems at the burst is probably fatal.
        More detail
        Not fully confirmed:
        • HM totem tolerance is from one forum player (Soarora), stated tentatively. One or two living totems was survivable on vet.
        • The exact HP thresholds for totems and the burst.
        03

        Voskrona Stonehulk Poxito

        Boss
        ☠ Wipe mechanic
        • Death essence phase: she leaves the stone body and becomes an invulnerable skull in the middle, casting room-wide AoEs. Heal and shield through it.
        • Dead Voskrona Guardians leave an aura that makes her and other Guardians invulnerable while they stand in it. Pull her out of it.
        Tank
        • Face her flamethrower away. It follows you.
        • Adds and the boss push each other around. Expect her to drift off you, and reposition.
        • Keep her out of the Fatal Pool. The achievement 'Parched Stonework' asks for this, so it probably empowers her.
        DPS
        • Kill the Guardians and Flamerocks close together in time so she can't revive them one by one.
        • Break free fast if you're immobilized.
        Healer
          👁 Watch for
          • Poxito's skull rides inside a huge stone Voskrona golem.
          • A ground standard (like a DK's) does AoE damage. Get out of it.
          Hard mode · veteran only

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

          • More HP.
          More detail
          Not fully confirmed:
          • This fight is the least documented. Tethers and beams that increase damage are mentioned (Fextralife, PTS feedback) but not explained.
          • What the Fatal Pool does. Only the achievement mentions it.
          • HM changes: no source lists any beyond HP.
          04

          Talen-Lah and Bar-Sakka

          Final boss
          ☠ Wipe mechanic
          • Dirge: Talen-Lah summons two mages that each make a big circle. At least one player must stand in each circle, or the whole group takes heavy damage.
          • At ~80% and ~40% Talen-Lah leaves and Bar-Sakka hits the group with a large AoE and a frontal cone. Block and stay out of the cone.
          Tank
          • Watch for Bar-Sakka rolling around the arena and throwing boulders. It can hit you from behind.
          DPS
          • Kill the skeleton adds coming out of his ground portals.
          • The fight ends when Talen-Lah dies, even if Bar-Sakka still has HP. Focus him.
          Healer
            👁 Watch for
            • Bar-Sakka: a giant Argonian behemoth that rolls around leaving AoEs.
            • Ring-shaped AoE markers with small AoEs around the edge. The middle and the outside are safe unless you stand in a small one.
            • Vet: Talen-Lah summons two shadow copies that slam their staffs.
            ↯ Alternatives
            • Telegraphed charge: before he walks forward a line shows his path. He fires small AoE tiles sideways, then forward at the end. Stand at the end of the line before he starts and roll through the last few.
            Hard mode · veteran only

            Activate: Banner before the boss (veteran). Poxito and Voskrona Stonehulk Poxito must have been killed on HM first.

            • More HP.
            More detail
            Not fully confirmed:
            • HM changes: no source lists any beyond HP. PTS players called HM 'easier than Exiled Redoubt'.
            • Dirge damage on non-HM is unknown (one forum player).
            • On PTS, Talen-Lah leaving could make Bar-Sakka get stuck rolling, forcing a wipe.
