The missile strikes unerringly, even if the
target is in melee or has anything less than total
cover or concealment. Specific parts of a creature can't be singled out. In-an-imate objects are not damaged by the
spell.
For every two levels of experience past 1st, the caster gains an additional missile. He or she has two at 3rd
level, three at 5th
level, four at 7th
level, and the maximum of five missiles at 9th
level. If the caster shoots multiple missiles, they can be targeted at a single creature or several creatures. A single missile can strike only one creature. The caster must designate
targets before rolling for
spell resistance or roll
damage.
