For me it wasn't the fire that kept drawing comparisons to Divinity. It was the writing. The opening is beat for beat Divinity tropes and it was off-putting. It took hours more gameplay and character development for that edge to wear down, though it has probably permanently shaded my first playthrough. Perhaps that opening was one of the first things written, and thus the most akin to its predecessor.

Once the game settles in, things feel less Divinity and more Faerun. The fire metaphor is apt though. Things do creep in from time to time to remind you who built this adventure. It's like a signature. I don't always like it, seeing the hand in this case is more jarring because of how sensitive I am towards the setting and gameplay. But the craft is so thoughtful otherwise, it's broken through those barriers for me.
