I still like my idea where the wizard can hit himself.. This really applys when a wizards trying to cast ata a target 5 feet away from him but counts squares so it wont hit him. Then he misses in any of the ways and can hit himself anyhow. ITs kind of funny really, this mage in my game tried doing that to a harmed dragon. He barely avoided getting killed due to a well timed heal spell but the dragon was in his face due to the fact he had to get close to cast harm. He cast the spell, missed the concentration check by 1 and rolled a 2 on the check. I moved his fireball so it hit him and the dragon, killing them both. It was quite funny.
