Thrower's Bandolier is a new item from Treasure Vault. It solves a set of problem that is in my opinion better solved by a Returning Rune:
You do not want to throw un-runed weapons, but it would be too expensive to put expensive fundamental and property runes on many weapons, as they are lost after 1 attack.
Here are the differences:
- Returning: 55 gp
- Bandolier: 60 gp + the individual price of the mundane items, but contains +1 potency rune (worth 35 gp)
- Returning: 0, as after the attack you have the weapon in your hand again
- Bandolier: 1, as you have to retreive a new one to be thrown (you can mitigate this by Quick Draw)
So by paying a feat (which for most classes will take a multiclass feat too, through Duelist), you can make a Thrower's Bandolier as good as Returning. Why would I do that?
