so levi's whole thing is like... it's their heart that's generating the electricity? so they can do kind of a lot of stuff, including your classic force lightning but also like very localized EMP bursts or whatever, but they don't want it to get to that point because the stronger the electricity they let out, the more it's been bouncing around inside them and damaging things. so they try to get all of this out on a regular enough basis that they don't blow stuff out around them (unless that's the goal) and also so they don't burn out their heart. basically they're not an all-powerful lightning god and they don't want to be that, so hopefully that helps?

can't believe levi's gonna have a big sis figure who's younger than them. i love this
