Castle Avernus Bone Chambers

At a glance

Corpse- and bone-filled chambers beneath Castle Avernus containing a sealed coin vault and a gargantuan skeletal beast.

Rage’s fear-driven retreat from a chamber of hundreds of corpses led the party down to this level.
An invisible seal protected a room full of chests containing gold coins stamped with Azalin’s face.
Rage broke the seal with his greataxe.
Carver determined that the coins were not magical.
An adjoining ossuary held a gargantuan bone golem, two bone dogs, and rising humanoid skeletons.
Carver summoned Pearl here for the first time.
The large beast withdrew toward a northern tunnel and appeared to be guarding something beyond it, though that remains unconfirmed.
A Boom Stick exploded in the tunnel, damaging the golem and Ignatius.
In the resumed battle, the party destroyed the bone golem and a large bone dog.
The chamber continued to raise fresh skeletons from its remains, suggesting an enchantment capable of replenishing the horde without end.
Carver consumed a scroll of summon undead to distract the horde while Ignatius, Rage, and Carver escaped through an animal-dug tunnel.
The skeletons could not cross the threshold into the safer antechamber where Ooru, Siv, and Voss waited.
Ooru, Siv, and Voss waited in a safer antechamber outside the battle.
The party crossed the chamber again to reach two previously unexplored prison rooms; Rage was struck by a poisoned javelin while entering the first.

Dangerous and uncleared. The bone golem is destroyed, but an apparently endless skeleton horde remains in the ossuary.
