Spell Brewing [3.5]

[Andion Isurand]

Looking for any tweaks that might help the wording or balance of this spell and any of my others (http://andionisurand.blogspot.com/2011/10/spellbook.html).

Temporal Battle Tide
Transmutation [Time]
Level: Sor/Wiz 7
Components: V, S
Targets: One creature/level, no two of which can be more than 60 ft. apart
Saving Throw: Fortitude negates (harmless) or Will negates

This spell functions like haste (PH 239) and slow (PH 280), except that each targeted creature that fails its save is either hasted or slowed as desired. Each targeted creature to be hasted may attempt a Fortitude save to negate the effect, which is considered harmless. Each targeted creature to be slowed may attempt a Will save to negate the effect.
This spell may not be countered or dispelled by haste or slow.

How about...

Temporal Battle Tide
Transmutation [Time]
Level: Sor/Wiz 7
Components: V, S
Targets: One creature/level, no two of which can be more than 60 ft. apart
Saving Throw: Fortitude negates (harmless) or Will negates

You gather up the strands of time in your hands and twist them to a shape more of your liking. All hostile targets of this spell are affected by a slow effect (as the spell), and all friendly targets are affected by a haste effect (again, as the spell). A successful Will save negates the slow effect.

This spell may not be countered or dispelled by haste or slow.

PS: your link doesn't work.
