I have a unit that is spawned with an item that has permanent invisibility and permanent immolation. The immolation won't work when the unit is invisible. I need a way to kill enemies as they get get close to this invisible unit. I tried to go into Gameplay constant and find something, but the best I could find was a was to allow invisible units to emit an aura. I made an Unholy aura that does damage instead of heals, but the maximum rate is -10 HP / sec, and that won't kill fast enough. Any thoughts?
