Spirit Form is an Source Skill in Divinity Orginal Sin 2.
I only encountered this skill in the final boss fight, if you know what enemy I'm talking about. When the enemy has this buff on them, if you try to attack them, it would just be like if you attack an actual spirit: things just go straight through their body without doing damage.
