I have an Archivist (6), Hierophant (5), Runecaster (14). I have been creating runes and for the most past it has worked fine. However, when I created a rune of Finger of death, I find it doesn't work. When I use the rune to cast on an enemy, nothing happens but a charge is used. My other runes have worked fine. Is there something I can do to get FoD working on my runes as I like the spell?
