Any spellcaster that can cast the find familiar spell (such as an apprentice, warlock, or wizard) is likely to have a familiar. The familiar can be one of the creatures described in the spell (see the Player's Handbook) or some other Tiny monster, such as a cranium rat, a crawling claw, a gazer, an imp, a pseudodragon, or a quasit.
This variant is intended for NPCs.
