I should make a character designed around casting Fireball as many times as possible.
Just for the moment where the DM asks me what I want to do, I answer "Fireball", they ask "are you sure?", and I reply by producing multiple pages representing my spell list and it's just "Fireball" over and over again.
@DavidCoffron Just use Hackmaster? Every spell level has a Sidewinder Fireball (Factor X), where each die of the fireball does 1d6+X-6 damage, minimum 1.
@Yuuki the main wizard character in this manga basically does that as his main combatmethod (the only spell he's mastered but he is so good with it that he cam best most with just that spell)
3.5 also had a feat where so long as you had a fire-type spell of a certain level or higher available to cast, you could make a miniature fireball-like effect at will, with its effectiveness scaling with the level of your highest prepared fire spell.
