What the difference between best build and late game ... do you also have an example for fire team seeing how i have ares and alaca
For fire team, you need a debuffer(i.e. Amat) and a healer(i.e. Brynhildr).
If you don't get Amat from gacha, then she's the best choice for miracle ticket.
For now, Cthulhu could fill the debuffer role.
