I like these suggestions!
Especially:
- Different Payloads: Exploding arrows, fire arrows, anti-gravity arrows. There is much fun to be had here, and it changes the nature of the bow in an interesting way. I like the idea that it changes what happens on impact and maybe doesn't cut in the same way anymore. Blunt arrows could also be a thing! Similar to getting hit by a hammer.
- Homing arrows: Tried it! Too powerful to happen to every single arrow, but might be a compelling thing to add as some sort of special ability!
- Saving Arrows: Sounds a bit complicated, but there is something cool about charging up multiple arrows and unleashing them in a swarm!
