A diminutive demonic being roughly humanoid in shape and standing about 2 feet tall

A Quasit is a diminutive demonic being roughly humanoid in shape and standing about 2 feet tall. It is a natural shape-shifter able to change at will into the form of a giant centipede, giant bat, or a wolf, all with horrific visages that set it apart from a normal animal. In all forms the quasit has 60-foot Darkvision. In its natural demonic form, a quasit attacks with its poisonous claws and bite. The poisonous claws cause an unnatural burning itch that will temporarily reduce the Dexterity of the target by 1 point for each successful attack. The points return 10 minutes after the end of combat. In its other forms, see the relevant monster entry for its attack forms. In addition to physical attacks, a quasit has several magical qualities available in any of its forms. They can **detect magic** at will, become invisible at will, and once per day can **cause fear** (reversed remove fear) as a 7th-level Magic-user. As an infernal being, a quasit is immune to electrical and poison attacks, and receives only half damage from acid, cold, or fire-based attacks. Magical weapons or spells are required to strike a quasit. In addition, so long as it has at least 1 HP remaining, a quasit r

Familiar. This creature is an option for spellcasters using the find familiar spell.

Quasits infest the Lower Planes. Physically weak, they keep to the shadows to plot mischief and wickedness. More powerful demons use quasits as spies and messengers when they aren't devouring them or pulling them apart to pass the time.

A quasit can assume animal forms, but in its true form it looks like a 2-foot-tall green humanoid with a barbed tail and horns. The quasit has clawed fingers and toes, and these claws can deliver an irritating poison. It prefers to be invisible when it attacks.

Demon of Discord and Disorder

Tirelessly destructive, quasits sow discord through nasty pranks, sabotage, and ambushes. These tiny demons use chaos and violence to terrorize others. By shape-shifting into harmless but ill-omened creatures or by turning invisible, quasits sneak into places where they spy for villainous masters or set vicious traps. Quasits delight in hiding in dark places and—when least expected—bursting forth to slash foes with their poisoned claws.

Quasits are usually overlooked and underestimated by other demons. This drives them to prove themselves through cruel acts or by seeking paths to the Material Plane. Among mortals, quasits sow senseless chaos, and they might find kindred evil spirits among violent cultists and magic-users.

A thing doesn't need to be big to be gut-flippingly dreadful. Just think of all the folks who're squeamish around spiders. Now imagine a spider as big as a cat and that wants to steal your tongue.

Soul worms formed by Demon Lords for service as familiars to chaotic evil clerics and magic users

Quasit are soul worms formed by Demon Lords for service as familiars to chaotic evil clerics and magic users. At will, quasits are able to polymorph themselves into any 2 of the following creatures: frog, bat, giant centipede, or wolf. Despite their rather low intelligence, quasits are quite crafty and cunning creatures. They are also used as tools by demon lords, who might communicate through them. Quasits are generally tasked with helping their masters to spread evil and chaos. In particular, they are often used to pervert lawful evil souls to chaos, which earns them rewards on their home plane of the Abyss. Ultimately, when its master dies, the quasit is charged with bringing the soul back to the Abyss. If the quasit has served well, it may be rewarded by being changed into a class A or class B demon. If not, they will be punished through becoming a kullule, soul worm, or even a quasit again.
