Casters are low hit point. My wizard died a few times when I was learning to play. I was playing on normal difficulty.

I played Solasta: Crown of the Magister. They are a very small company and did a great job with the D&D 5e rules. I had a blast playing it. So, I am looking forward to BBG3 with all the bells and whistles that Larian brings to the D&D game. It is going to be great.
