Does anyone know what a missile attack is considered? Magic Missiles? Arcane and Ice Bolt? Freezing Sphere? Is Bone Pointing attack a missile?
Thanks in advance 
I believe is only for Archer’s and such, I think all magic attacks are simply magic/arcane type.
I’m not sure that’s true, it seems odd for one of their most spammable abilities to have 0 effect on their own damage output.
Many skills put decay effect.
It has a DoT effect of it’s own, is not only about helping archers actually.
