Emergency Arrows

You take an item that can fit into one hand, and infuse energy into it and fasten it into any tangible, basic projectile of choice (arrows, non-explosive bullets, bolts, etc.).  If the material has an intrinsic property, the projectile can have secondary damage effects (ex: ice dealing cold damage), at the Dungeon Master's discretion.  You must have the ability to use the projectile in question, by way of a weapon, other cantrip or spell, or proficiency otherwise.
