Sure, mage armor, false life, and sleep are your friends. Shield is better at higher levels when you can burn a 1st level spell in a crisis. Mirror image is a reasonable spell pick at 3rd level.Has anyone had any experience with not doing this - with instead putting the second highest stat into constitution and planning to accept getting hit more often and just hope to soak it up?
Look at "wall" spells - those that create barriers or zones that the enemy will not wish to cross. That assists your allies as well as protecting yourself.
