Larian Studios Forums Divinity 2 - Ego Draconis (English) Help/Tips/Tricks Help with Naberius and Getting the Creature

I am very early on in the game (level 6), (in the new revamped version of Divinity 2) and have found Naberius in the cave. But when I suggest working with him on the creature, he just says the last one ran away and that he will show me how it works but will not build one with me. Now my question: what do I have to do to get him to offer a quest or quest chain that will lead me to actually control a creature. I know it involves getting body parts and a crystal (in a quest called Vigor Mortis) but why is that not being initiated yet? Do I have to reach a certain point in the game before this can happen? Thanks.

You need to find the crystal skull that the creatures keep running for, which is available after you finish the main plot quests in the starting section of Broken Valley. At least in D2:ED you could retrieve the skull starting from about level 10-12.
If you want a hint for the location, after you get access to the full valley,
