Crypt of Hearts I
A ruined Altmer school full of undead and Daedra. Three bosses (Archmaster Siniel, Death's Leviathan, the Ilambris Twins) and three minibosses. Hard mode is the Scroll of Glorious Battle on the Ilambris Twins.
- The Mage Master (first miniboss, skeleton with caster slaves): tank and spank. Block his Uppercut; step out of the purple Negate bubble (silences you and wipes ground AoEs) and the red ice ring.
- Uulkar Bonehand (lich in a side room south of Death's Leviathan) is optional. Easy: stay out of his red ground rune and back away from the lich crystals before they explode.
- Dogas the Berserker (dremora with skeleton and banekin adds): tank stacks him with the adds for AoE. Block his heavy, face him so he can't stab your back, and break free of the Soul Tether stun.
- Hard mode: read the Scroll of Glorious Battle before engaging the Ilambris Twins (veteran only, achievement 'A Crypt for Two').
Archmaster Siniel
Boss- Corpse Explosion: a channeled group-wide hit you can't avoid that drops everyone to low health. Be topped up when it lands.
- Hold him still and pull each zombie wave onto him so it dies in the AoE.
- Kill each zombie wave fast: he can't be damaged (or is shielded) until it's dead.
- Burst-heal right after Corpse Explosion; group HoTs before it.
- Altmer necromancer mummy. 'Now the dead will rise' = three zombies coming in.
- Induce Horror: a large spectre that fears whoever it hits.
- Red circles on the floor = Necrotic Ritual DoT. Step out, don't run around.
More detail
Mostly a zombie-wave fight. Stack the zombies on the boss, step out of red circles, and be healthy for Corpse Explosion.
- UESP says he is invulnerable until each zombie wave dies; Xynode describes a damage shield you burn through instead.
Death's Leviathan
Boss- Paralyzing Slam after Ignite: once he's on fire, the stomp also sends a fire wave that knocks everyone down. Block it or you take both hits at once.
- Face him toward a wall, away from the group, so Trample (charge) hits nobody else.
- Block the stomp every time.
- Get out of the charge path and the big red stomp circle.
- Giant bone colossus. At about half health he walks to a brazier and comes back burning: damage goes up and his charge leaves a trail of fire.
- High DPS can burn him before Ignite matters.
More detail
Simple bone colossus. Tank faces him at a wall for the charge; everyone blocks or avoids the stomp. After he ignites at the brazier, stay off his fire trails and block the stomp's fire wave.
- UESP: Ignite happens at around 50% at a brazier. Xynode calls it an Enrage 'at low health'.
Ilambris Twins (Athor and Zaven)
Final boss- Athor's heavy (Axe Strike): delayed, huge knockdown. It lands before the swing visual: block as soon as he winds up. Non-tanks die if they don't block.
- Zaven's Rolling Fire: a straight line of fire at his target. Step sideways. Nearly a one-shot on DPS or healer.
- Pyrocasm: Zaven lights the statues, then a large red circle explodes around him. Get out; blocking does not stop the knockdown.
- Hold Athor (blue, axe) out of the centre; keep a ranged taunt on Zaven (red, mage).
- Don't get knocked down by Pyrocasm while Athor is winding up, or into a lightning dome.
- Kill Zaven first. If Athor dies first, Zaven fills the room with fire.
- Athor: blue Xivilai with a two-handed axe. Small lightning domes on the floor (Electric Prison): don't stand in them; they stay put.
- Zaven: red Xivilai fire mage. Lines of fire crawl to the statues around the arena before Pyrocasm.
- Once Zaven dies, Athor calls lightning bolts (red circles) around the room. Small steps, don't panic-run.
- Killing one twin enrages the other. With enough DPS, burn both down together.
Activate: Veteran only. Read the Scroll of Glorious Battle before engaging the twins (achievement 'A Crypt for Two').
- Both twins get more health and deal more damage. No new mechanics.
More detail
Two Xivilai at once. Tank holds Athor outside the middle and ranged-taunts Zaven while DPS kill Zaven. Then move Athor to the centre and burn him while dodging lightning strikes. Lightning domes accumulate, so don't let the fight drag.
- Exact spot of the Scroll of Glorious Battle isn't given by UESP or Xynode (usually near the boss arena entrance).
- Xynode says Rolling Fire is near-lethal on non-tanks; UESP calls it moderate damage.
