With 1.20 and the new enemies, the bowtorn has been the largest pain, so while I'm sure someone else will come up with something eventually I wanted to try my hand at designing a trap that can get bowtorns to the player. My concept sort of works, the pit is about the minimum distance that bowtorns will shoot from and has "staircases" to encourage moving towards the player. If the player stands still the bowtorns will eventually let water carry them to the player.

While making this I also discovered that limiting a bowtorn's side to side movement will make them more likely to get to the player and try stabbing them. If the initial stretch on the pathways towards the player could move the bowtorns just enough they'd come themselves (Unfortunately, they get quite skittish if the player makes any movement).

Anyway, I'd love to see what other people have done to take care of bowtorns during temporal storms.
