This is essentially the same fireball as in the Player's Handbook, but with a slight change in the material component. Since bats are almost unknown in the Arctic, this spell was developed using whale oil. Note that like the paper in fire aura (q.v.), the whale oil is a replacement worked into the spell, not an optional substitution. A wizard learning fireball from the plates would need a supply of whale oil, although perhaps another organically produced oil could substitute. In the tropics, dolphin oil should work fairly well, say -10% to -20% on range and -1d6 damage. At that point, the wizard simply needs to convince the local sailors (preferably Greek) to go kill a few dolphins and bring back their carcases. Spell research into even other components is of course also an option.
