Unhallowed Grave
An ancient burial canyon looted by Draugrkin necromancers. Five main bosses and a chain of three optional secret bosses unlocked by grappling. Several fights use the grappling bow you pick up early.
- Grappling bow: pick it up at the start. Grapple posts are needed in Keeper of the Kiln and Ondagore, and for all the secret bosses. Falling into the chasm kills you.
- Hard mode is only on Kjalnar Tombskald: destroy Kjalnar's Skull Totem before the fight (veteran only).
- Secret bosses (Nabor, Voria, Voria's Masterpiece) must be done in order, each buff unlocking the next. Their grapple points disappear once the final boss dies.
Hakgrym the Howler
Boss- Bone Sunder (heavy): tank blocks at high Health; non-tanks must dodge-roll.
- Werewolf phase: at low Health he becomes a werewolf behemoth, back up to 50%. His charge tramples everyone in its path and leaves skeletons. Get out of the line.
- Face him away. Keep the skeletal werewolves on him.
- Kill the Woeful Totem the moment he throws it. It keeps firing ice bursts until destroyed.
- Flesh Abominations: he frees one at ~70% and another later. Kill each as it comes; don't let both be up.
- Cursed Ground: a lich-crystal spear comes out of the floor under you, with a filling circle. Step out before it pops.
- Werewolf: stomp sends shockwave circles out in all directions; Forceful Slam is a large growing circle.
More detail
Phase two is a burn with more mobility. Totems and crystals continue. The abominations' slam leaves a lingering pool.
- Thresholds differ: UESP says abominations at 70% and 30%, Xynode says 70% and 20%. UESP says he transforms at 10%, others at 0%.
Nabor the Forgotten
Secret bossHow to spawn: Listen for a voice ('You must find me...'). Follow the hidden entrance in the shadows, keep left in the big room, and grapple up to Nabor on his platform. Needed to unlock the other two secret bosses.
- Chilling Comet: he rises to call a comet and platforms show a spreading AoE. Grapple to a platform without the AoE or you die / get blown off.
- Forgotten Deadeyes (archers, from ~75%) take aim at a player and knock them off the edge. Interrupt or kill them while they channel.
- Hold him still and block his heavy.
More detail
Buff Forgotten Strength: more Weapon and Spell Damage, your grappling bow damages enemies, and hidden grapple posts are revealed (needed for Voria). Interact with the glowing Unhallowed Urn after the kill.
Keeper of the Kiln
Boss- 'Flames are rising in the vents!' You must solve the sigil or the whole group burns to death.
- Solve: non-tanks grapple up to the three upper platforms and find the glowing Sigil of the Forgotten. Activate it; it shows a count of 1–4 marks.
- Tank drags the Keeper onto the floor sigil with the same count. Then break her damage shield. She stabs the sigil and the fire stops.
- Hold her on one of the four floor squares. Block her uppercut.
- Statues come alive as adds at regular Health steps. Stack them on the boss.
- Don't break her shield before she's on the right sigil; she just recasts it.
- Watch for archers up top. They shoot you and rain arrows on the group.
- Don't over-burn. Too many statue phases at once floods the room.
- A red shield on the boss and flames in the floor vents mean the kiln is starting.
- The correct floor sigil gets a swirling effect once the upper one is activated.
More detail
Code65536's hint: look up. Only the activated upper sigil tells you which floor sigil is real. Statue adds can chain you back down if you're up top.
- Kiln timing: Xynode says 90/60/30%. UESP and Fextralife don't give thresholds.
Eternal Aegis
Boss- Ring of Blades: a spinning ring AoE at medium range. Stand right next to the boss or far away. The ring blocks attacks from outside.
- Lesser Aegises split off and spin too. Kill them before their Shield Breaker channel finishes, or they explode.
- Face it away and block its fanning strike.
- Blade Throw: swords fly out and boomerang back along circle markers. Stand in the gaps. Xynode says it can be interrupted.
- Two fused mournful aegises with blades. Lesser copies look like small versions of the boss.
- Stack and burn: with strong mitigation and heals, stack right under the boss and cleave everything through the spins.
- Safe: spread out of the circles, kill the lesser copies, then return to the boss.
Voria the Heart-Thief
Secret bossHow to spawn: Needs Nabor's buff. At the edge in front of the Eternal Aegis room, look north for a hidden grapple post across the cliff. Grapple from post to post to Voria's platform.
- She escapes twice to another platform with a damage shield. Grapple after her fast, break the shield, then interrupt her. If she gets away, she's gone until you reset the dungeon.
- Grapple jumps are double-hops over the chasm. Miss one and you fall to your death.
- Block her charged chop (it staggers her). Hold her as she becomes a Bone Goliath around 50%.
- Kill her totem fast, same as Hakgrym's.
More detail
Buff Voria's Authority: better Magicka/Stamina Recovery, and you can break Voria's magical seals (the door to her sanctum). Touch the glowing artifact after the kill.
- Escape thresholds: Fextralife/Xynode say ~75% and ~40%; UESP says 70% and 15%.
Voria's Masterpiece
Secret bossHow to spawn: With Voria's Authority, go back to the sealed door (Voria's Sanctum) and open it. The boss is right inside.
- Oozes keep getting bigger through the fight. Grapple through an ooze to split it into smaller ones that die easily.
- Stay out of the swamp water and the slam's poison pools.
- Keep the boss central around the middle grapple post. Place each slam pool next to the last one so they don't fill the room.
- Taunt the two-handed skeleton that spawns after each stomp right away. Its heavy kills non-tanks.
- A flesh colossus with a mace hand. Oozing Slam: a big circle where it slams, then a lingering ooze pool.
More detail
Kill grants Abominable Bulwark (more Max Health, less damage taken) and the 'Knock Knock' achievement.
Ondagore the Mad
Boss- Poison phase: a green dome covers the middle. Grapple out to the outer platforms and kill the Skeletal Spellbinders there, then grapple back.
- Drain Soul phase: he glows white and pulses deadly blasts. Hide behind a pillar (your grapple point glows yellow when you're covered), and kill the 4 Menders healing him.
- Hold him mid-platform. Grab new adds fast, especially a bone colossus if one spawns.
- Ghost adds die to AoE. Kill the colossus if it appears; its heavy needs a precisely timed dodge.
- A lich on a round platform ringed by pillars, over a chasm. Grapple posts line the walls.
More detail
Phases alternate until he dies. Mechanics can overlap. Code65536 noted tanks sometimes can't grapple while being hit.
- Phase timing: Xynode says poison at ~80/40% and hide at ~60/20%; Fextralife says the hide phase starts at 50%.
- Only Xynode mentions a bone colossus add here.
Kjalnar Tombskald
Final boss- Imbued Skeletons come from the edges toward the empowering circles. Kill or CC them before they get there; empowered ones blow up for huge AoE.
- Abyss / grave-dust shockwaves: he flicks his hand and fast shockwaves race out. Poorly telegraphed and high magic damage. Block if you see it.
- Tzirzhalir's Freezing Breath (after 50%): huge, no indicator. Block or shield.
- Face him away, block his heavy (unblocked = dead tank).
- Break free from the grasping skeletal hand under you at once.
- Stack Health and spell resistance; incoming damage is high.
- Focus the slow two-handed skeleton first. If it reaches the middle it heals to full.
- Don't step on the runes from his spin. They explode.
- Runic Spin: a big circle under him, then bone-like runes scattered around the floor (mines).
- At 50%: he calls up Tzirzhalir, a giant bone colossus. It has no Health bar and dies with Kjalnar. Its fireballs leave big ground AoEs.
Activate: Veteran only. Destroy Kjalnar's Skull Totem before engaging.
- Cages: clusters of cage-like rocks appear on the ground and explode in a chain. Get out immediately; a non-tank caught in one dies.
- About double HP and much heavier hits. His fast light attacks can kill the tank too, so many tanks nearly perma-block.
More detail
After 50% the fight is the same plus the colossus. No hard enrage; you can take your time if you handle the skeletons.
- Where the Skull Totem is. Achievements only say 'destroy his unholy totem'.
- HP figures (8.5M → 18M) come from Xynode only.
