Thanks for the Champions of Krynn flashback. 12-year-old me used to love exploiting the item duplication save glitch; the game was practically over once I found a wand of fireball. Character classes were irrelevant after that.

Kobolds? Fireball. Zombies? Fireball. Draconians? Absolutely use fireball. Paladin death knight lich? Believe it or not, fireball.
