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!
The sculpt spells description says that your party automatically passes their saving throws, but ice storm still does half damage on successful save. It also says “and take no damage from them”, so maybe you’re right and the divine guardian attacked us since I attacked it? I’m not quite sure. I should have checked the combat log.
