D1 (Ossuary)

All of the monsters present here begin the encounter hidden. Characters with a passive Perception of 14 or greater are able to avoid being surprised.

The owlbear skeleton has been replaced with an offalian, but its general purpose and place in the warrens remains the same. I suggest the following encounter for a party of five adventurers:

• 3 Skeletons
• 3 Skeleton Archers (see Dungeon #166)
  
• 1 Offalian (see Open Grave)
  

Total: 1,050 xp (Level 5 Encounter)
