Arrow of Ranged Silence
When you shoot a “Grey Shaft of Nonsense”, you see animation of the arrow, plus an animated ranged silence spell flying out toward the target. The ranged spell animation only shows when you successfully hit the target with your arrow, but not if you miss. If the spell is successful, you correctly get the green cloud on the target.
The arrow's spells are “cast when strikes” and should not show ranged spell animation.
