So I can buff the enemies up and make them vulnerable with this, as long as Death/Darkness? Seeing as this'd kill everything but Obsidian and possibly Ivory Dragon too, instantly, I can't quite see the pointer... hm... well, unless it's buffed or a buffed Vulture, but then a good buffed Vulture wouldn't be as killable with normal damage and preferably Mutated/Reversed... I say, this still should be cheaper, as the two parts of the after effect balance themselves out. Maybe cost 3 base 1 upgrade like the Lighting.
