Lore & Background​

Quasits are small, bat-winged fiends from the chaotic depths of the Abyss, serving as scouts, spies, and familiar spirits for evil spellcasters. These mischievous demons delight in corruption and chaos, using their shapeshifting abilities to infiltrate mortal society and spread malevolence. Despite their diminutive size, quasits possess the cunning intelligence of their demonic heritage and the patience to execute long-term schemes.

In their natural form, quasits resemble tiny humanoids with bat-like wings, sharp claws, and wickedly intelligent eyes. They can assume the forms of various small animals, making them excellent infiltrators and information gatherers. Many evil warlocks and wizards summon quasits as familiars, appreciating their loyalty, magical abilities, and complete lack of moral scruples.

Combat Tactics​

Quasits prefer stealth, deception, and hit-and-run tactics over direct confrontation. They use their shapeshifting ability to scout enemies while disguised as harmless animals, then coordinate attacks with their masters or allies. In combat, they rely on their poisonous claws to weaken foes and their flight to stay out of reach of melee attackers.

When serving as familiars, quasits use their telepathic link to provide tactical information and can turn invisible to avoid detection. They excel at harassment tactics, using their small size to hide in unexpected places and strike when enemies are distracted or vulnerable.

Encounter Ideas​

1. The Perfect Pet A quasit in animal form has infiltrated a noble's household, posing as a beloved pet while gathering information for its warlock master. The party must expose the fiend's true nature without harming the innocent family that has grown attached to their 'pet.'

2. Familiar's Revenge A quasit whose evil master was recently defeated seeks vengeance against the party responsible. It uses its shapeshifting abilities and knowledge of the party's habits to orchestrate a series of 'accidents' and misfortunes, striking from the shadows.

3. The Informant Network Multiple quasits operating in a city serve as an information-gathering network for a demon cult. The party must track down these shape-changed spies and disrupt their operations without alerting the cult to their investigation.

4. Corrupted Sanctuary A quasit has taken residence in a forest shrine, slowly corrupting the natural magic of the area. Local druids and forest creatures are falling under its malevolent influence, and the party must cleanse the sacred site before the corruption spreads further.
