The Prism constribution is a special rule and isn't so much of a shot as it is giving up the ability to shoot the cannon for a different effect. Just like according to the
FAQ it can contribute to a cannon in a game being played the other side of the planet if you wanted (assuming line of sight) and the contribution ability does not prevent the underslung gun from firing at whatever else you please.
Of course if the weapon is destroyed, it is what supplies the ability so in that case you cannot use it but if the fire prism is only able to fire snap shots it still may voluntarily give up its firing ability.
