Magic Missile Battery (3.5e Spell)

You can never have enough dakka.

You inscribe a magical rune on your body which grants you magic missile as a spell-like ability at will. This counts as a 3rd level spell for the purpose of interacting with other spells and effects. In addition, you are immune to the force damage spells of 2nd level or lower, and are always aware of the presence of force effects within 60 ft.
