Alespec (Familiar Variant)

Shapechanger. The Alespec can use its action to polymorph into a beast form that resembles a rat (speed 20 ft.), a raven (20 ft., fly 60 ft.), or a small lizard (20 ft., climb 20 ft.), or back into its true form. Its statistics are the same in each form, except for the speed changes noted. Any equipment it is wearing or carrying isn't transformed. It reverts to its true form if it dies.

Limited Telepathy. The Alespec can magically communicate simple ideas, emotions, and images telepathically with any creature within 100 ft. of it that can understand a language.

Fey Sight. Magical darkness doesn't impede the Alespec's darkvision.

Magic Resistance. The Alespec has advantage on saving throws against spells and other magical effects.

Familiar. The Alespec can enter into a contract to serve another creature as a familiar, forming a telepathic bond with its willing master. While the two are bonded, the master can sense what the Alespec senses as long as they are within 1 mile of each other. While the Alespec is within 10 feet of its master, the master shares it's Magic Resistance trait. If its master violates the terms of the contract, the Alespec can end its service as a familiar, ending the telepathic bond.

Claw (Bite in Beast Form). Melee Weapon Attack: +5 to hit, reach 5 ft., one target. Hit: 5 (1d4 + 3) piercing damage, and the target also takes 2 (1d4) necrotic damage.

Invisibility. The Alespec magically turns invisible until it attacks or until its concentration ends (as if concentrating on a spell). Any equipment the Alespec wears or carries is invisible with it.
