I've recently come into possession of a lovely boomerang.
Its description says something about how wonderfully it returns to one when thrown, but I can't for the life of me figure out how to throw it.
It's in the melee weapons part of the inventory, and functions like one: when you press Y, you just swing it like a stick.
The same is true of spears: some of their descriptions go on about how well weighted they are for throwing... but there doesn't seem to be any way to throw em.
Am I missing something?
