While motionless, the Skulker is indistinguishable from burned stone, bone, or rubble.

If the Skulker acts before a creature in combat, its first attack against that creature deals an extra 21 (6d6) fire or necrotic damage.

When the Skulker takes slashing or piercing damage, molten blood sprays.
Creatures within 5 ft. must make a DC 16 Dex save, taking 10 (3d6) fire damage on a fail, half on success.

Ceiling Predator.

Whenever the Skulker drops from the ceiling onto a creature, that target must make a DC 17 Dex save or be knocked prone and take 14 (4d6) bludgeoning + 7 (2d6) fire damage.

Pack Stalkers.

If at least one Skulker is within 10 ft. of the target, the Ashen Skulker has advantage on all attack rolls.
