Planar Bestiary
A hunakak is deliberately crafted out of an evil soul by a more powerful demon; they do not originate naturally (unlike demons of vengeance, murder, and so on).
A hunakak's body is almost entirely a monstrous face as tall as a human, with a gaping mouth and fly-like compound eyes. Their form is concave, like a giant mask, with a ring of small fingerlike limbs that allow them to crawl or grasp things. Although they appear to be only a few inches thick, their wide-open mouth seems to be deep enough to fit an entire halfling in it.
Motive: Form a bond with and aid another creature (usually a demon)
Environment: Anywhere in the multiverse, as a mask worn by a mortal or a demon
Health: 9
Damage Inflicted: Moderate wound (4 points)
Armor: 2
Movement: Immediate; immediate when climbing
Modifications: Speed defense as level 5 when reduced to the tiny size able to fit a standard humanoid
Combat: If unbonded, the hunakak's bite inflicts damage, and on a failed Might defense task, an additional 2 points of Speed damage (ignores Armor) from necrotic energy.
The hunakak can choose to fix a creature within short rang with a "damning gaze," inflicting 4 points of Speed damage (ignores Armor) from necrotic energy on a failed Might defense task. If a victim dies from this attack, their soul is absorbed by the hunakak. When the demon returns to the Abyss, their absorbed souls are transformed into minor demons (and usually consumed or handed over to a more powerful demon).
The hunakak can change their size from normal to mask size as their action. While mask size, their bite inflicts 2 points of damage and on a failed Might defense task, 1 additional point of Speed damage (ignores Armor) from necrotic energy.
If worn like a mask, the willing host gains a telepathic connection with the mask allowing communication. The host can also see in the dark, and the demon can use their damning gaze attack without interfering with their host's actions. However, at any time and for any reason, the hunakak can end their service, ending the telepathic bond.
Interaction: A hunakak is sometimes awarded to a mortal who serves the Abyss. The mortal wears the demon (reduced in size) like a mask and can use their abilities, but if the mortal is ever slain, the demon absorbs their soul and brings them back to the Abyss. Hunakaks sometimes serve other demons, including being worn as a mask, but this is more of a standard partnership or minionship.
Use: A local noble has recently taken to wearing a strange and unsettling new mask.
GM Intrusion: A target of the damning gaze feels the grasp of the Abyss, in addition to regular damage, and descends one step on the damage track.
