I was attempting to use Flaming Sphere, the 2nd level Druid spell, on a swarm. I was told that it wouldn't hurt the swarm.
The swarm rules are pretty vague, but say that if it targets a single target it cannot hurt a swarm. Flaming sphere hits stuff in a square, the text uses the word "target" but I think that's only because more than one thing cannot exist in a square other than a swarm. Swarm rules also mention that some evocation spells can hurt swarms.
So can flaming sphere hurt a swarm if they fail the reflect save?
