"hmm, I wonder how many gravestones she'll have to break up to even build a Heart in the first place" >load game, head to nearest cemetery >....10 or 20 stone units per out of 240 needed to build Heart, sometimes yielding nothing
and like, with the capsules how many graves actually are there? (I have already asked if there are at least enough in mod questions thread, I'm just putting this here because I'm laughing at how the first thing is "rebuild the town" and Persephone's go-to is "destroy unused things to build my own things" because that's how it is at home
if there's not enough she's going to slowly realize after going through like 10 stones, be stuck there with piles of stone (she might be able to make like...bowls? If she can create a magic blood fountain she can create a stone bowl/basin) and some intense hunger she may or may not know how to handle
