Goblin Vampire

Twice a goblin's height, it has smilodon-like fangs reaching mid-chest, shriveled black taloned hands, and pulsing orange eyes. It cares only for slaughter and may no longer understand any language.

Every glimpse of its burning eyes demands a fear check, even from veterans of the sight. Each failure grants it an extra Hit Die, never beyond 10 total, for turns equal to the victim's Hit Dice: a 5th-level fighter who panics gives it 1 HD for five turns. Strength 18/50 means +1 to hit and +3 damage, and if both claws land it holds the victim and automatically gores for another 2d6+3.

It cannot regenerate or become gas, and priests turn it as a spectre. Charm, hold and other magic aimed at mind or life fail, as do poison and disease. Moonlight burns it for 1d4 per round and holy water for 1d6+1. Staking its heart with obsidian destroys it instantly.

It wanders alone hunting blood and fear, so far only in nearby human lands, and hates goblins, stalking them by day when they are weakest.

Only one source makes these monsters: the curse a dark hag coven places on anything stolen from them. A thief who keeps the item becomes a goblin vampire over twenty hours; dropping it partway stops the change but does not reverse it. It must feed on blood or fear every day or lose a Hit Die, perishing at zero, and must have had both within any three-day span, or it loses another Hit Die on day four and each day after until it feasts on both.
