Yeah, a Lucrezia copy in a sparky body has a lot more options (though clank Lucrezia full of wellspring water was plenty scary). Agatha'd already ascended/drunk wellspring water (Dyne, in her case), however briefly, which let Lucrezia-in-Agatha do so relatively easily. In a sparky body that'd never taken in wellspring energy Lucrezia-in-a-sparky-body might have to jump through a few more hoops.

Everything attempt at summoning Lucrezia so far has targeted sparky women. Is that Lucrezia's preference, or an actual requirement? Or a requirement for the flame-and-wellspring system? Could she ascend the way Snacky did, or the way the Polar Lords do/did?
