Arrows of Chaos

You touch a quiver containing arrows or bolts and draw on its internal magic. The arrow tips begin to shift color in the light. A creature hit with this arrow must make a Wis saving throw, in addition to it’s normal damage, or be afflicted with short term madness. This effect lasts either for the duration or until 6 arrows have been fired.

On a miss, the magic stays active. For the next minute, a creature that casts a spell within 5 feet of where the arrow lands fails it’s spell, and must roll on the wild magic table. The arrow returns to normal after it causes wild magic once or after the duration ends.
