D6 (Skull Corridor)

The lesser necrophidius monster featured here needed to be replaced. The bonewretch skeleton from Open Grave works just as well. Not only can they just as easily represent the skeleton of a small monster (like a derro, perhaps) as they can a child, but their Rattling Shift power is a perfect analog for the necrophidius' ability to dissemble its bones to slither across the ground. I suggest the following encounter for a party of five adventurers:

• 3 Bonewretch Skeletons
• 1 Acid Spraying Skulls

Total: 825 xp (Level 4 Encounter)

Position the acid skull trap sprayers far enough apart that the entire room is covered by their
burst areas.
