What's the better of the two : CoC or Fireball (Help my strat) (in General)

I'm wondering what to turn my single mage into.... what to do with him! I am going to eventually turn it into a tank once i get NW, but for now strat ideas?

Using a ToJ, I'd say CoC if you live past ranged most battles.

Cone of Cold is the more powerful of the two but you need to ensure your mage lasts into melee. Fireball is great for ranged but the damage you do to your familiar in melee can be harmful. Using CoC on a single mage works best with a ToE. I've been using CoC on my mage team and it's worked better for me than Fireball or Magic Missile ever did... You could always get a ToA and make your CoC mage a CoC archer.....

For a good example of a single CoC archer check out Warchild's char Alucard.... =)

I'd say as long as you don't fight team with CoBF, Fireball is the better option. From what I've seen, being a single mage, you can't fight until the last round of melee (25 rounds melee). Also being a single mage, it's needed to kill fast, take advantage during the range round (just like the advantage of using Elbow).
