Sorry I didn't mention that. It is in 2.50.2
Screenshots (the hitbox may be a bit hard to make out, but it is shown).
These are all reflected magic type (though their sprites are different).
This is a reflected beam type lweapon (made to look like an arrow).
I would have posted screenshots earlier, but I didn't think that the cheat's alterations (which show the hitbox) would be visible.
