Quite simply, I'm looking for a good way to make a small-ish fog cloud that will obscure vision, for use with the Slyph's Cloud Gazer feat.
A Smokestick is too small with only a 5' radius, but Obscuring Mist and similar spells are too large with a 20' radius. Sadly, I don't think there's a "Shorten Spell" antimetamagic, and I haven't found any cloud abilities with a size in between these.
Just use Obscuring Mist or Fog Cloud, then move into a position where you only need to see through 10' or so. Rounding corners is typically the place for this.
