As an action, a slashing or piercing weapon you touch becomes becomes sharpened. For the duration, the weapon deals an extra 1d6 damage when it hits.
If the attack misses by 4 or less, the weapon deals half as much damage.
Alternatively, you can touch a quiver containing arrows or bolts, granting the ammunition pulled from it the same effect. The spell’s magic ends on a piece of ammunition when it hits or misses.
