Ice storm does not apply the save vs slow.
Should it? I don't recall such a thing, and nothing on Ice Storm on the wiki.
This would be in reference to these changes.

- By choosing Greater Spell Focus: Evocation, you get access to the benefits of old EFU:A elemental perks. Your chosen Flame Weapon element adds a special effect to spells that deal elemental damage.
In brief:
Cold: Damaged targets make a saving throw or are slowed for 1 round.
Fire: Damaged targets make a saving throw or are set on fire. They continue to receive 1d4 damage per round until a successful save is made.
Acid: Damaged targets make a save or experience -2 Armor Class for 1d6 rounds.
Electrical: Damaged targets spread 1d4 lightning damage to other nearby targets.
As with the other magic changes lately, this may be subject to further adjustment.
Should be fixed next reset, I think.
