An umbral hulk, U, is a type of monster that appears in SpliceHack, SlashTHEM and Hack'EM. It is a counterpart to the umber hulk that shares the same bite and claw attacks, and its gaze can blind targets instead of confusing them.
Umbral hulks may generate as peaceful towards neutral characters.
Umbral hulks are somewhat easier to deal with if you blind yourself manually, e.g. with a blindfold - fortunately, blinding from their own gaze also prevents it from affecting you further.
The umbral hulk originates in the biodiversity patch.
Umber hulks are powerful subterranean predators whose
iron-like claws allow them to burrow through solid stone in
search of prey. They are tremendously strong; muscles bulge
beneath their thick, scaly hides and their powerful arms and
legs all end in great claws.
