Queen Vespy is weak to both so hell yeah for that one, but it's also good for the quest where you fight Congalala (fire) and Emerald (Ice) or Daimyo (Fire) and Plum (Ice).

I find Fire & Ice a somewhat less useful duo-element ds... but the elemental value IS nice. 450 base, which is highest for both.
