This spell enchants an arrow or bolt (referred to as "missile" from here on out) so that it freezes in time and space. The spellcaster places it in the position she wants it as a part of the spell. The missile may be magical.

The missile remains frozen in place until something passes in front of it, something touches the arrow, a moderate wind (21mph+) blows upon it, or the spell duration ends. At that point, the missile moves suddenly as if it was just fired. If a creature is in the line of fire, he is considered flat-footed. Use your base attack modifier to resolve the attack. Two missiles enchanted with time's arrow cannot be placed within ten feet of each other; if a second missile is placed too close, that spell fails and the first missile is triggered.

Focus: The missile. Material component: Sand from an hourglass.
