Currently on rank 35 and about to get Soul Joan as I need 30 more Soul points. Was contemplating on getting Amaterasu as she would be a better fit than Mars. Just grinding SP Quests and Raid Quests, can do some AP25's but getting owned on anything above. Just wanted to see if I am headed in the right direction?
