How much damage will I do?

[Samka]

Again, this is an MF sorc, on Battle.net.

Again? Not in this thread.

If this is a sorc for MF, you want to be killing meph as quickly as possible. So the more fireball power, the better. I wouldn't want to be running meph with less than an 8k fireball. You will also be more useful in parties with a higher power FB or meteor.
