  • Sunlight Sensitivity. While in sunlight, the umbral shambler has disadvantage on attack rolls, as well as on Wisdom (Perception) checks that rely on sight.
  • Tenebrous Agility. The umbral shambler’s speed is doubled while in dim light or darkness, and it doesn’t provoke opportunity attacks when it moves, provided it moves only in dim light or darkness. In addition, when a creature that relies on sight attacks the umbral shambler while the shambler is in dim light or darkness, the attacker has disadvantage on the attack roll.
  • Void Traveler. The umbral shambler doesn’t require air, food, drink, sleep, or ambient pressure.


  • Multiattack. The umbral shambler makes two Claws attacks.
  • Claws. Melee Weapon Attack: +5 to hit, reach 5 ft., one target. Hit: 5 (1d4 + 3) slashing damage plus 3 (1d6) necrotic damage.
  • Twisted Step. The umbral shambler can project itself beyond reality for a short time. Until the start of its next turn, the shambler can move through objects as if they were difficult terrain, provided an object is no more than 3 feet thick and at least one side of the object is in dim light or darkness. It takes 5 (1d10) force damage if it starts its turn inside an object.


This otherworldly humanoid’s body has distorted, twisted features and skin that shifts constantly from scaly, to slimy, to fleshy, and back again. Its true form is blurred and hard to see, and the very shadows seem unwilling to reveal its full form. These creatures of the Void appear humanoid but can never be seen clearly, their bodies always seeming to blur and shiver.

What can be seen is disturbing: limbs and digits in strange proportions, distorted facial features, skin that is scaly one moment, slimy and translucent the next. Their bodies move with strange spasms and tremors.

Corrupted by the Void. Exposure to the Void can warp creatures both mentally and physically. Umbral shamblers were once humanoid travelers, but sudden and overwhelming exposure to the Void has complete transformed them into twisted remnants of their former selves. More rarely, long term Void corruption can lead to this sort of transformation, especially among humanoids who practice Void magic or in priests of the Void. The satarre are said to know a ritual that transforms any human into an umbral shambler.

Humanoid Hunters. Umbral shamblers take great delight in stalking humanoids, moving swiftly under cover of darkness in forests or cities to appear to surround a victim. They terrorize such prey above all others, delighting in the destruction of those they once resembled.

Void Assassins. Because of their ability to step through walls and doorways, umbral shamblers make excellent assassins. They serve various Void cults in this way, taking orders from dark prophets, void cultists, and the satarre.
