Conduit
5th-level enchantment (Artificer,Bard,Sorcerer,Wizard)
- Casting Time: Special
- Range: Touch
- Components: V, S, M (up to 2 missiles)
- Duration: Instantaneous
You can channel a spell into an arrow or other missile for later use. Upon casting conduit, you can cast a spell of 1st through 4th level into the missile by touching the missile as the spell is cast. You expend a spell slot, but none of the spell's effects occur. Instead, the spell transfers into that missile for later use. The spell imbued into the missile must have a maximum casting time of 1 action, and it must have an area of effect.
Any creature thereafter can make a ranged attack using the missile, and the spell is cast when the missile strikes an object. The spell is cast using your spellcasting ability, and it is centered on the object that the missile strikes.
When you create a conduit in this way, it must be used within 8 hours. After that time, its magic fades and is wasted. You can have a limited number of conduits at the same time. The number equals your Intelligence modifier.
