Transmute Air to Vacuum (3.5e Spell)
From D&D Wiki
|Casting time:||1 standard action|
|Target, Effect, or Area:||Any air elemental|
This spell literally turns air to vacuum but is typically used as an attack against air elementals. It turns them permanently into a vacuum elemental of half the hit dice. Success on the save means that the transmutation doesn't occur, but the elemental still takes 10d12 damage.
