Planar Bestiary
These monstrous creatures resemble three snakes joined at the tails to face in different directions, with each head having three eyes and three prominent fangs. Their scales tend to match the environment where they grew up—rust for Acheron, grey for the Gray Wastes, red for the Hells, and so on. When trinavars have to move fast, they bend their necks into loops so they can roll like a sphere or cylinder. Their size and odd locomotion make them easy to spot when moving, so trinavars hunt by lying flat and waiting for prey to approach them.
Trinavars' three-lobed eggs are considered a delicacy by Lower-Planar creatures but are unpalatable to most Material Plane natives.
Motive: Hungers for flesh
Environment: Across the Lower Planes, alone or in groups of two or more
Health: 36
Damage Inflicted: Minor wound (3 points)
Movement: Short; short when climbing
Modifications: Speed defense as level 3 due to large size; perception as level 7; resists blinding, frightening, and mental.influencing attacks as level 7 due to having three heads
Combat: A trinavar attacks three times each round, striking with their three fanged heads.
A struck target takes 2 additional points of Speed damage (ignores Armor) from poison on a failed Might defense task. A creature that fails two or more poison defense tasks in the same round must make another Might defense task or be paralyzed and unable to make physical actions and defenses for ten minutes, or until they succeed on a Might defense task on their turn to end the effect early.
If a trinavar takes 5 or more points of damage from a single attack, one of their snake bodies is severed but continues to attack as a separate level 4 creature with 12 points of health. The main trinavar retains the health of the original creature (minus the severing damage), rounded down. If this happens again to the main trinavar, they split in half, each snake attacking as a separate creature with half the health of the original. (The trinavar can't be split more than twice.) The severed pieces rejoin and heal when combat is over, forming one creature with full health.
Interaction: Trinavars are akin to the snakes they resemble despite their size and tripartite aspect. They prefer live prey but often subsist on carrion, and they are particularly common scavengers of the battlefields of Acheron. They abandon old meat for fresher food, especially something too weak to fight back.
Use: An inn advertises a new delicacy, a dish "beloved in other realms," guaranteed to dazzle the palate of the discerning eater. However, the quiche-like specialty usually turns a diner's stomach. More worrisome is the sound of hissing coming from the cellar where the eggs being used to create the delicacy were stored.
GM Intrusion: The trinavar sprays their poison a short distance, hitting a character in the face, blinding them for a round, and inflicting 3 points of Speed damage (ignores Armor).
