The School of Evocation wizard's 2nd-level Sculpt Spells feature says:
The chosen creatures automatically succeed on their saving throws against the spell, and they take no damage if they would normally take half damage on a successful save.
My English isn't that good and I'm a beginner, so I think that's the problem. Beginning at 2nd level, you can create "pockets of relative safety" - what does that mean?
So what is it for if it takes no damage? I understand it this way: If you choose more than 1 creature, then you take no damage.
I couldn't find anything and no one seems to have this kind of problem. I hope you understand it.
