I'm curious if you are looking for something that is realistic or just arcade? Now, I can't say what an experienced archer could do if they shot multiple arrows at once, but if you think about a bow, even if you did what is pictured in that Lord of the Rings screenshot, your arrows are going to essentially shoot along a vertical line. The top arrow will hit higher than the bottom arrow. And the same patter will apply for any additional arrows. The end result? You could potentially hit a single target with multiple shots, but the chance of hitting multiple targets is almost zero. Add in the time it takes to load that many arrows, and you'd probably be able to shoot close to the same number of arrows individually, with more accuracy, and with more targets than if you did a multishot option. Again, I don't know what an experienced archer could do. I'm basing this just on what relatively little knowledge of archery I have. But it doesn't seem like anything that makes any real sense. That movie was clearly not realistic when Legolas did that. Now, I know there are bows/crossbows that can handle multiple shots. But what real gain do you get? How quickly can you shoot compared to individual shots? How is your accuracy? Does it even make any sense?
So, are you looking for something that's entirely arcade? Nothing wrong if that is what you want, of course. But it doesn't seem like something worth adding to vanilla.
Maybe someone who is an experienced archer could verify how this would work in real life (not just someone who shoots arrows now and then, but someone who actually competes and does well). I'd be interested to know. The following are the negative effects of multiple shots from ChatGPT, which may or may not be all that accurate.
- Reduced Accuracy – Controlling multiple arrows means each one is less precise, making it hard to aim properly.
- Weaker Shot Power – The energy of the bow is split between arrows, reducing their range and penetration.
- Inconsistent Flight Paths – Arrows may not leave the bow at the same speed or angle, causing unpredictable spread.
- Difficult to Execute – Requires exceptional skill, technique, and custom arrows to work effectively.
- Not Practical for Combat or Hunting – Historically, archers relied on rapid single shots rather than multiple arrows, as speed and accuracy were more important than quantity.
It certain doesn't seem like a good option unless it's just an arcade style option for fun.
