Shade creeper

Shade creepers are small creatures that are a recurring problem in Jrusar.

Description
Shade creepers are small gray creatures, with leathery, noseless faces and mouths full of teeth. Their eyes are red or black and they wear dark-colored cloaks and can wield daggers. Their feet are clawed.

When the black-eyed variety of shade creepers attack, they deal both piercing and necrotic damage. When they are killed, they spontaneously combust, dealing a small amount of fire damage to those in the surrounding area. When an attack misses them, they can make a slippery dash to to move away without provoking opportunity attacks.

Known shade creepers
A group of shade creepers with black eyes attacked the party in the Weary Way Tavern. They appeared to be under the control of the dwarf Dugger, who was also fighting the party.

After the combat, Imogen and Laudna said that they'd previously helped Zhudanna deal with some shade creepers, but that the ones they'd seen had red eyes, not black, and didn't explode when killed.

Trivia
Shade creepers resemble darklings from Volo's Guide to Monsters in that they wear dark cloaks, have gray skin and toothy mouths, stab with daggers, practice thievery, live in the chambers beneath other species' cities, have blindsight, and combust when they die, damaging nearby creatures.
