Currently, the scoped crossbow is not really very useful, because it can't account for gravity. You can't point at something and shoot it. Firing at something far away is actually harder with the scope, because you have to aim so high you can't even see the target. Trying to code the scope to adjust for this when firing seems tricky.

Meanwhile, the Precision enchantment is not particularly useful either. Reducing the random divergence of a shot just doesn't matter very often in practice.

Suggestion: make the Precision enchantment substantially increase the projectile speed, such that you can shoot long range targets using the scope.

Great idea! Btw, this exact thing was already planned for the next update, lol.
