Didn't know AoI had ranged attacks (really need to finish that some day). Fireballs nearly qualify, but creating a unit that you then use in suicide combat isn't quite the same.
Kael implemented ranged combat for archer units as a spell/ability, even though it would have made more sense to use real ranged combat like certain other mods that came with BtS did.
