What you are about to see is not the stuff of medieval legend... although it should be. If someone were able to do this in the middle ages, they would likely have been set on fire for witchcraft. That's how amazing it is to watch an able archer hit a target from around a corner.
For once, the reality of something is way cooler than it could ever be shown in the movies, thanks to archer Lars Andersen.
Andersen is a Danish archer who is kind of like the Mythbuster of the archery world. He shows how amazing feats in archery can still be done in the modern world, without a modern bow and arrow set up. He's proven that ancient Saracen archers could really fire off three arrows in 1.5 seconds, as history recorded. He can catch arrows in mid-flight, just like your Dungeons and Dragons character. He can deflect an incoming arrow with another arrow. He even demonstrates how to catch an arrow the use it to shoot another target.
In the 2017 video below, he's demonstrating a technique used by English and Arab bowmen from the days of yore: shooting heavy arrows around corners – he even says it can be a really easy thing to do for any archer, you just lace the arrow on the string in the wrong place, slightly off-center. The off-center firing causes the air resistance to kick the arrow back, making it rotate into a turn.
He even demonstrates a "boomerang" shot, where the arrow turns completely around a corner.
The arrows will not hit the target on a turn with the same force as it would a straight-on target, so it's unlikely to kill someone taking cover from your arrow barrage, but it will make them think twice about the cover they've chosen.
