just got them, not sure what they do...
They’re fodders for Soul Enhancement.
I think they give your soul cartas exp.
they're kind of like the aurora blobs for child evolution, just translated to soul enhancement for carta.for example when you evolve a child, you can use aurora blobs and childs, but you'd rather not sacrifice usable childs right? so you just use aurora blobs because that's their purpose.same idea for soul enhancement on carta, you can use napping places and other carta, but other carta have usable stats, so you sacrifice napping places because that's their purpose.i hope that gives an idea..
Ahh ok Thanks :)
