You know how magic bows, crossbows, slings and firearms can bestow their enhancements to their ammunitions? Yeah, I'm looking for an item, probably a gauntlet or glove, that will do the same thing for thrown weapons.
Let's say I have a +1 flaming gauntlet and I throw a javelin with it, the javelin doesn't normally get the flaming property. I'm looking for something that would do that.
Pretty sure that would be a custom item with DM approval, I don't think such an item exist. Probably because gauntlets and other worn items don't really affect thrown items. Closest thing in the game is this:
Atlatl: An atlatl is a thin piece of wood or antler used as a lever to hurl a specially fitted dart. An atlatl gives much greater range to a dart, but must be loaded like a projectile weapon. Your Strength modifier applies to damage rolls when you use an atlatl, just as it does for thrown weapons. You can fire—but not load—an atlatl with one hand. Loading an atlatl is a move action that requires two hands and provokes attacks of opportunity. The Rapid Reload feat can be taken for atlatls, allowing you to load a dart as a free action. Atlatl darts are the size of javelins but have fletching, and can be used as javelins without an atlatl.
Which you could then enchant, but it's really just categorized as its own stone age ranged weapon.
But I guess this would work exactly as you need it to, except that you wont be able to wear it on you.
