Tagamaling buso

A tagamaling buso was the victim of the infected claws of a tigbanua buso and cursed to turn into one each night.

Ecology
Any humanoid wounded by the claws of a tigbanua buso risked contracting its disease or curse, if they lacked the fortitude to resist. Those infected inevitably became a tagamaling buso.

Thereafter, every night after sunset, the victim was at risk of transforming into a tagamaling buso. This was slight at first, only a 1-in-a-100 chance on the first night, but increased steadily each night, becoming in a 2-in-a-100 on the second night, and so on. It lasted throughout the night and ended at sunrise, when the victim changed back to their original form with no memory of the experience,   though they might find themselves terribly fatigued.

In the ninety-nine days after infection, the condition could be lifted with cure disease, remove disease, or remove curse. But on the hundredth night, the chance became certain, and the victim would become a tagamaling buso every night without fail. They could not be cured  by any magic less than a miracle or a wish.

A tagamaling buso could not transmit the infection to others. They also lacked the tigbanua buso's aura of paralyzing fear.

Description
A tagamaling buso looked like a tigbanua buso in most aspects. When a victim transformed, their feet became elongated and bony, their hands grew sharp claws, their teeth grew into wicked fangs, and most notably their eyeballs fused into a single orb, colored red or yellow. Otherwise, they retained something of their original build and height, appearing shorter and stockier than a tigbanua buso as they didn't have its lean figure and long neck.

Combat
Tagamaling busos attacked everyone they encountered, using their new claws and fangs to slash and eat them. They were as durable as they were in life.

Behavior
When transformed into a tagamaling buso, the victim was as mindless as an animal and much more savage, simply attacking—and then eating—whatever and whoever they came across. Their minds were consumed with rage and animal instincts, and they could not do anything requiring thought, nor could they use any special skills, magic, or other powers they might know normally.

Perhaps mercifully, they retained no memory of what they'd done when they turned back.
