AS=Attack Sprit. Low AS teams are used to maximize sprit usage. Eg. Your fighting a sprit with 2,000 def, it doesn't make sense to use an atk team of 4 one star and a five star (15,000 atk/ 50AS) when you can defeat it with an all one star team (3,000 atk/30AS). "WG" are Wandering Ghosts who you encounter at random during tower events. Pure and Fallen are sprits you encounter during guild events.
