Does Vanish Count As Villager Magic?

Asking for Altar of Sanctification. I assume flamethrower counts, so it's fitting that he isn't using it, but is Vanish magical, or more of a technique like Charge, Multihit, and Arrow Storm?

 

He's a ghost. He's turning transparent outside of his control. Notice how he gets more and more panicked as the forms keep going? He only starts Vanishing in his later forms when he's losing control of himself more completely.

Also, magic isn't exclusively from the villagers. The warlocks of Mage Island are human and got there while the seas were roiling, there's the ancient ruins in Almuj, Bob's techniques, the Twains...plenty of examples.
