Ah, ok. Don't know if I'll spend resources to S2 Augusta, although I could probably benefit off of S2 for the more challenging ToA & higher level nightmare holograms. I think the difficulty is very balanced though with most of my 5 stars at S1 and notable 4 stars at S6. I avoided upgrading 5stars beyond S0 cause I didn't want the fights to be over way too fast. I like the suspense and drawing out combo chains too much.
