Now we all know that ammunition can be enchanted and some of the things that can be put on it are obvious like flaming.
But ammunition doesn't have a table in Ultimate Equipment or anything like that.
Taking flaming for example, it appears in both Melee and Ranged and I've always thought this could be put on a bow or similar. But unlike some enchantments such as Keen it doesn't actually specify what it can be put on which I assume means it can be put on any weapon.
I started wondering about all this after looking through some spells and noting that Keen Edge can be used on a set of 50 ammunition similar to enchanting them. But the Keen enchantment is only in the melee category. Now arrows in their description do say they can be used as a improvised melee weapon but so could anything really. So could Keen be put on arrows? Plenty of people have wanted a Keen enchantment for ranged weapons and I even home brewed an equivalent after finding a Keen Longbow in Second Darkness that was no longer valid in Pathfinder.
But could we have been putting Keen on arrows all along? And if so are other melee enchantments available for ammunition? Are we meant to exclusively use ranged weapon qualities and if so which ones?
Where is the list of ammunition enchantments?
