Ah I see thanks.
So, if I have 1 save at 41-50, but my upgrades are low, start a new save slot, get some more upgrades until +30/30, then finish up 41-50?
That way my second slot will have the upgrades too, and I can start a new save (as I cleared my primary) to keep this up until I have my desired weapons (rotating both slots)? This is what I can see to my understanding, correct if wrong!
Most of the palace can be cleared with any job setup. For the last 10 floors you will very likely need a healer, or be very careful with pulls and what not, ut even then you could get unlucky and trigger traps that gonna end up wiping you, so might as well suicide to reset if that happens.
Yup I intend to main heal it.
