With the way people talked about her I expected NP1 Summer Melusine to be kind of just sitting around not being that useful but her huge battery lets her pretty comfortably farm a decent variety of nodes even at NP1 using my Johanna and Lady Avalon and a borrowed Castoria so I don't have to use my own Castoria's bond. I really like it. Nice bonus is it's Extra class so can farm any of the hands too. And most of the inputs are on turn 1 so it's particularly comfy to farm while watching stuff.
