What do i do after defeating uber perpetua? Am i supposed to dump money to slime shope or has next area not been created yet?
The latter, pretty much. There isn't much content available for the capital, yet.
Ya isn't the capital basically a month or 2 old now?
Yeah, this was an intermediate step to show that progress is being made.
Which is a good thing. It honestly always makes me think of Corruption Of Champions 2, they recently started to really overhaul stuff while also releasing major main story progress stuff.
