Gaseous Form [1]
(Alteration)

Range:  0
Components:  V, S
Duration:  1d6 rounds + 1 round per level
Casting Time:  3
Area of Effect:  Creature touched
Saving Throw:  Negates

This spell allows the wizard to turn the creature touched into a pink cloud of gas, for the duration of the spell. If the creature touched is an unwilling recipient of the spell, he gets a saving throw, with a successful saving throw negating the spell.
The spell's effects are identical to that of the potion of gaseous form, with regards to movement rates, and the effects of a gust of wind spell. However, the wizard - if he casts the spell on himself - can turn non-gaseous at any time.
