An abominable horror from deep beneath the earth, an umber hulk burrows into cave complexes, dungeons, or Underdark settlements in search of food. Those lucky enough to survive an umber hulk attack often remember precious little of the incident, thanks to the umber hulk’s mind-scrambling gaze.
Devious Delvers: Umber hulks can burrow through solid rock, forming new tunnels in their wake. The steel-hard chitin of its body can withstand the cave-ins, tunnel collapses, and rock falls that commonly follow it. Burrowing into the wall of a cavern or passageway, an umber hulk lies in wait for creatures to pass by on the other s ide, its hair-like feelers sensing any movement around it. When it explodes out in a shower of earth and rock, its unsuspecting quarry turns to face the oncoming threat-and is entranced by the umber hulk’s bewildering eyes, forced to stand helpless as its mandibles snap shut.
Mind Scrambler: Many survivors of an umber hulk encounter recollect little about the attack, because the monster’s confusing gaze scrambles their memory of the event. Those who have fought and killed umber hulks recognize the signs. For other denizens of the Underdark, grisly tales of vanished explorers and wanton destruction speak of an unknown foe. Umber hulks take on supernatural status in these harrowing stories, many of which convey the same warning: once an umber hulk has been spotted, it is already too late to escape it.
Known Weaknesses: None Discovered.
Method of Attack: An Umber Hulk prefers to lie in wait just out of vision bursting forth from stone, or darkness, using its scrambling gaze to confuse its foes. Once confused their foes stand very little chance against the hulk’s massive claws and mandibles.
Methods of Successful Vanquishing: Overwhelmed by 6 or so trained combatants (still a close call).
