Quick reference

  • Win condition: Kill the Warden after silencing two Bone Choir channels.

  • Default positions: Keep adds east, boss west, soak spikes in pairs.

  • Tank: keep Ossuary Warden facing away from the party during Bone Choir.

  • Healers: shield before Marrow Spike; expect a raidwide immediately after.

  • DPS: stop casting and move for Hollow March; resume once safe spots light up.

  • If two people share a spread marker, both die. Treat spreads as hard fails.

Full explanation

Marrowdeep Hollow is a fictional A Realm Reborn dungeon written so the site can demonstrate encounter-guide structure without naming a real duty. Clear the fight by surviving two scripted phases and finishing Ossuary Warden before the enrage cast completes.

Phase 1: establish space

Ossuary Warden opens with Bone Choir. The cast draws a cone on the ground. Stand outside the cone, then collapse to the north safe slice when the telegraph fades.

  1. Tanks establish enmity with a full combo before the first Bone Choir.

  2. Healers pre-shield the offtank if a tank buster follows within two GCDs.

  3. Melee hold positionals until the cone resolves; ranged stay on the south arc.

After the first cone, Ossuary Warden fires Marrow Spike. This is a stack marker plus a delayed puddle under the stack point. Soak together, then leave the puddle before the second pulse.

Phase 2: split and resolve

At about 55% HP, Ossuary Warden leaps to mid and starts Hollow March. Four players receive spread markers; the rest soak a centre tower. Spreads walk to the cardinals. Tower soakers stay mid until the tower detonates, then rotate clockwise one slice for the follow-up line AoEs.

  1. Call spreads early so melee do not steal a cardinal from a ranged player.

  2. Pop party mitigation on the tower hit. The damage is heavy but predictable.

  3. Raise any death before the enrage window; Limit Break 3 is optional on Normal.

Variants

Default (recommended): north tank, south party, cardinal spreads, mid tower.

Prog variant: both healers soak the tower while DPS take all spreads. Use this if your melee keep dying on cardinals.

Farm variant: ignore the optional add and burn. Only do this once the party consistently clears the tower sequence.

FAQ

Does Bone Choir cleave through invuln? No. A well-timed invulnerability covers the tank buster that follows it.

Can one person solo the tower? Not on this placeholder duty. You need at least three soakers or the tower wipes the party.

Where do I stand for Hollow March? Spreads on cardinals, everyone else mid until the tower pops, then one slice clockwise.
