Time's Arrow

This spell enchants a missile so that it freezes in time and space. You may reposition the missile as part of the action to cast the spell.

The missile remains frozen in place until a creature passes within 120 feet in front of it, something touches it, the effect is dispelled, or the duration ends. At that time, the missile moves suddenly, as if it was just fired or thrown with a range of 120 feet. If a creature is in the line of fire, the missile makes an attack using your spell attack modifier. On a hit, it deals the normal damage of whatever missile type was used + your spellcasting ability modifier. If the missile's damage varies by launcher, the GM decides which damage dice it uses.
