>Nope. I can also do it with Baleful Polymorph, which is 5th level.
Baleful Polymorph is single target, and targets Fort save, which is generally the strongest save. So if we're using Baleful Polymorph as the baseline, that would ALSO make this 9th or MAYBE 8th level effect, since 3-4 levels higher is where multitarget versions of spells(especially of the Save or Suck/Save or Lose variety) generally are.

Enh. Maybe you're right. The mass Save or Suck spells tend to be 7th--9th, using Archon's Trumpet as an example.
