Exact chaining groups (early May, 2018) - sorting them by number of unique units in the group. Did not include single-unit groups. Counting equippable abilities/items as a unit. Finding the matches was done mostly automatically, but the process isn't perfect, and identifying who the actual units are was generally done manually. I tried to come up with a reasonable name for each group, usually either after a common ability or the most standard member of the group, but it wasn't always apparent to me what to call everything.

Orlandeau family

Running Fire is Lid. Like, regular story Lid. She has a 15% chance to do it with fully enhanced Invention. This is the enhanced Aureole Ray frames, but even that is kind of overshadowed in JP. Loren and Kunshira also share these frames, except they have innate dual wield, so it's really 60 hits for them. They're also both automatically Lightning/Wind, where Lunera is Light/Wind. Given the different behaviors of these moves and the future prevelance of Loren as a chainer, it seems reasonable to name it for both.
