The Thirteenth Throne
A cheaper version of the iconic Rune Shot that Gun Mages use.
You can cast a Close spell onto this ammunition. When you fire the missile, it takes effect as if you were standing at the spot where it fell. For example, you could charge an arrow with Lightning Fork and fire it at a faraway group o ffoes.
It has to be fired quickly – you don’t want to burn out the magic!
Even better, you can cast the spell on an ally’s missile, and then have THEM fire it.
