I personally find Lilith to be the most versitile Neverborn master. The ability to draw a target to herself and then potentially kill it, while at the same time possibly placing one of her crew into position is very valuable. While she does not survive well in a group of enemies, her high defense and disappear trigger makes her very sufvivable against a single figure that attacks Defense, in my experience. I have never found Lilith to be dependent on her in-theme crew to be effective. I tend to keep her skulking in the shadows, pulling an enemy into her web of death, letting her crew gather the victory points while Lilith herself offers a very credible threat to most enemy models, either directly with her greatsword, or indirectly by moving the enemy and some of my own models.
