Magic missile is a spell that, if successfully cast, will do a fixed amount
of damage to the target.  The missile cannot be blocked, however certain
magical creatures are capable of absorbing the energy of spell to heal 
themselves.
Blue dart is similar to magic missile, save that the spell sends a blue gout
of flame at the target in an attempt to burn them.  Some magical fire based
creatures are also healed by this spell.
