Get World Position from UV Space and Vice Versa?

Let’s say I want an archer to shoot an arrow into a monster that has advanced deformations. How can I make the arrow stick to the monster’s mesh (and not just one bone of the monster)?

Is there some way to obtain the world location of specific UV coordinate on the monster’s texture?

Is easier to get the Hit location, get bone / socket and attach while “keeping relative position”.

I know but that’s not what I’m asking.
