Wizard 1: I have only two cows, but with Prestidigitation I could make them tasty, soil, clean or blue. Once per round, all the time, for a whole hour. I can even warm or cool them. But I'm afraid of their Attack of Opportunity since my AC is 11 and my HP is 5.
Drunken Master: I have two cows. When I'm drunk, I deal over 40 damage with each.
Assassin: I have two cows. If you touch them, DC 30 Fortitude or you'r dead.
Incowtatrix: I have two cows, both appliable two any spell only at +1 spell level.
Rage Mage: I have two cows, both at full caster level when I'm raging.

Batman: "The true crimefighter always carries everything he needs in his utility belt, Robin."
