I found this spell online and kinda like the flavor of it but it seems weak to me. Any thoughts on balancing it?
Glacial Cold
School conjuration [cold, elemental - ice]
Level druid 2, ranger 2, sorcerer/wizard 2
Casting Time 1 standard action
Components V, S
Range medium (100 ft. + 10 ft./level)
Effect 20-ft. radius spread
Duration 1 round/level
Saving Throw Fortitude half
Spell Resistance no
You create a zone of icy cold within the spell's area, creatures that end their turn in the area of effect take 1d6 points of cold damage
Thanks,
David

The nearest equivalent is Flaming Sphere. Compared to that, this is a) bigger, b) immobile, c) less damaging (saves aside) and d) cold. So that's 1 medium advantage, 2 significant disadvantages and one slight advantage.
Options:
1) Creatures who fail to save are Slowed for 1 round. [so more likely to take damage again, as well as being arrow-fodder]
2) Damage +1 per 2 levels
3) 30-ft radius spread.
Personally, I'd do #1.

It is really more of a utility spell than an attack.
This spell Zone of Glacial Cold, is from the 3.5 book Frostfell.
The book contains several options (feats/PrC) that only work/get stronger in areas of cold.
So the spell is intended to be a convenient way to create a cold area, not really as an attack spell in itself.
That said, if you want to use it, I think Mudfoot's Option 1 and Option 2 would work
