Is there any way to duplicate an online-mode save? I want to try spending a bunch of shadow cores to see if upgrading talismans is worth it, but I want to be able to revert if it's not.
Yea but that won't let you test it out on a map to see if it was actually worth it.
I also regret making an online save. Apparently offline saves can be copied online, basically giving you the best of both worlds. There really should be a "copy to offline" option.
