[Midget Gems]

I think my favourite Bard spell would have to be Mirror Image, with maybe any Charm spell close behind. Once in combat my Bard is always singing, so there's normally not much to do except stand around. So instead I cast Mirror Image and have my Bard act as a decoy, running round in circles singing (and dancing) while my ranged missiles rain down on the enemy. Pretty sad tactics, but effective.
