The SHD AA Assault of Shadows I think is pretty weak, the hate generated from it doesn't seem to be as much as from Terror of Kaezul and it takes up a slot as a debuff so you can't cast it over and over for extra hate. This AA costs 5 points to get, so you'd think it would be as good as Terror of Kaezul or even slightly better, I know it's a mana free hate spell but unless you use it with Terror of Kaezul it's not really worth it. I suggest either increasing the hate generated from it to be equal to or greater then Terror of Kaezul, or make it so it's not a debuff so you can cast it over and over to gain hate.
