A-to-Z Challenge, U: Üuloch (New Oe/BX/1E Monster)

Today's A-to-Z monster came from the cover of an old pulp magazine and the illustration is a redraw. Unfortunately, I failed to save the source cover (came up with this one a while back) so I'm lost on which magazine it was to give any credit to the original artist (tried to look again; couldn't find it). Also, I think I originally wanted to find the story in which it appeared and give it that name and stats to match, but remember not being able to find a copy of the story, so I went with my gut.

Üuloch

DESCRIPTION Üulochs are winged monstrosities with a head that features a gaping mouth and a stacked pair of eyes. The dark red, slimy skin of the üuloch has the appearance of congealed blood, almost as if the beast was “inside out.” Though they are mainly airborne flying creatures, they are able to “walk” (though quite slowly) via the hook-tipped fingers running through their winglike bodies. On its initial attack, a üuloch attempts to sink as many of it’s piercing hooks as possible into its target (one “to hit” roll, with resulting damage determining the number of hooks that have successful been sunken into its victim.) If a üuloch sinks at least 10 of these hooks into a target, it may then dig into that target with its razor-sharp teeth (doing 2-12 points of damage.) If both these conditions are met (at least 10 points of damage with its hooks and a successful “to hit” roll with its bite), then the üuloch will continue to drain blood from it’s victim at a rate of 1-6 hit points per turn, and will not release a victim until the victim or the üuloch is dead. When a üuloch drinks more than 24 hits points of blood, the extra blood that it drains will seep through it’s skin and congeal on its outer surface, eventually “peeling away” from the üuloch’s body while it is in flight.
