Here's one more short Divinity II: Ego Draconis trailer, this one features the Necromancer power, 'arise my pet'.

In this new video, viewers will encounter the powerful Necromancer, a collector of limbs and other parts of fallen enemies who resides on your Battle Tower, waiting to do your bidding. The Necromancer’s chief talent: combining body parts to release the power of "The Creature", a custom-created "pet" that player’s can party up with for extra healing or tanking power.
