Answer: Yamatai.
Complete the story up to the point where the final boss goes to the cave and that's it, before even going they give you the item that unlocks the forbidden thief class which gives access to the skill of opening any chest when you level it up to 15 or simply by having that class active, although it is bad, the chaos hero class gives better advantages and more points for skills and is from the previous list, the sealed one.
Now I ask: Does anyone know at what point on the map you recruit nero and neris? Or is it that they only appear at the end when you would have to go to the last tartarus?
Reason: given that the master skills even of species give more skill points, nero and neris as a base have or I think they have many species and if you add the ones that Prometein can give, that pair along with Luka and the bug I want them to be my final team that I put all the meat on the grill, since after my little trauma with the first primordial weapon, I haven´t stopped exchanging characters for team and except for luka none of them convince me, since every time I find a new disaster or apostle, they break me into a thousand pieces and I don´t want to lower the difficulty of paradox, since to my liking, it´s the most fun, since the vast majority of enemies are immune to almost everything and so it´s more fun to play, since there are skill combos that would literally make the game boring from how broken they´re if they weren´t immune.
