"The Will of Ashan" - "Heart of Darkness" [2nd campaign, 5th mission]

SA and ULTIMATE Ability are the same thing. I obtained it once in the original game's campaign while playing as demons. In this campaign, I didn't even try to get it. Also, I don't aim to get SA when playing with friends as Necropolis in HotS. However, in the next campaign, I might try to obtain it. I haven't decided yet. I leveled up both heroes in Darkness, Summoning, Education, Sorcery, and Luck. Currently, I'm at the beginning of this mission. I've captured one castle and defeated one demon.
