Improved Magic Missile

The improved magic missile conjures deadly bolts of magical force that unerringly strike their targets, inflicting 1d4+1 points of damage each. However, improved magic missile can generate up to 10 missiles. The caster gains one missile at 1st level, and then one additional missile for every two experience levels past 1st level (two at 3rd, three at 5th, and so on). Note that this spell is identical to the 1st level magic missile for wizards of less than 11th level. Any protective magics that stop magic missile also stop this spell.
