I am currently 2 months or so into Fantasica at the moment. My current roster consist of a lot of 4*, several of them max'ed level, and a near max'ed 5* (Curious). One thing that confuses me is that there is no built-in clan/guild within the game itself, though (event aside).
Right now I am trying to figure what is common and not so I can gauge on how many TEs are they worth. Most likely I will need to sell off all of my goddesses to be able to buy additional decent 5*.
