I have a player that wants to have a miniature Mi-Go as a familiar. He has no qualms of basing the stats on another familiar, he just wants the appearance of a Mi-Go. What sort of familiar do you think I should treat it as? Maybe a monkey or a hawk?
A mi-go can fly and has claws, I don't think that should be negotiable. A hawk or owl might be a start for stats for a mini mi-go.
This unnaturally graceful creature has a bulbous fungoid lump for a head, spiny insectoid wings, and a tangle of spiky, clawed legs.
The Sawleg Locust flies and has a bite. These stats are close enough, I think, with reskinning the bite as a claw.
Let him use Improved Familiar to upgrade it. Not to a full Mi-Go, as Imp Familiars don't normally go above CR 3 or 4.
