I almost caused a TPK in a big fight right now by dropping ice storm on top of my team. Everyone still took massive damage, and it killed Shadowheart’s divine guardian which she had just casted. Read your spells carefully before assuming it’s safe to cast them on top of your party!
I think if you cast an evocation spell that you got from a different class, then sculpt spells doesn’t work
Ice storm is from the wizard class though. I got it by leveling up.
