Create Food and Water
Good comments, you guys.
When playing a cleric, I must admit I'm highly enamoured of Speak With Animals. I had one character who always had it, everyday through his career.
At high levels, Searing Light and Flame Strike are my friends. At all levels, CLW and its companions up through Resurrection are no doubt the most important spells. I really like Tongues and True Seeing, too. Protection from Evil is great too, and I wait for "Create Food and Water" with a cleric almost as much as I wait for Fireball with a mage. Command is fun, but it rarely works.
For mages, Magic Missile and Fireball are indeed the most obvious, but Rope Trick has saved our lives many, many times when we had a wizard with the Extend feat. Detect Magic, Dispel Magic, and Break Enchantment also save many lives.
Finally, I have a great fondness for Leomund's Secure Shelter and Helping Hand as "concepts", but I've never actually used them as a PC.
In Ken Burns' "Baseball" documentary, someone said the difference between football and baseball is:
- Football is played on a gridiron, to the rigid control of a timeclock, measured to the inch with chains, to plays ordered by the numbers and executed by players whose job is indicated by the number on their back. The object is to get the ball in the other's guy end zone. It's a game of the industrial age and ground warfare, a metaphorical version of the World Wars.
- Baseball is played on a field, at a park. The game lasts as long as it takes, and everyone gets a turn at bat. The object is to get home safely.
Leomund's Secure Shelter, Create Food and Water, Rope Trick, and Speak With Animals are more in the baseball side of D&D. Magic Missile, Fireball, and Searing Light are more the football side.
