Can anyone give an estimate of an approximate Attack power that can reliably beat ultimate difficulty without needing an Elixer? (Assuming a neutral element team running Sol + Andromeda)
I think it is not much. Still it is depend on your team. The damage of ixion double attack can cause more than ten thousands. So your party at least has hp more than five thousands. 6k or 7k is the recommended hp. Well debuff can fix that.
