Robin Kit Explanation Please

So I’m trying to decide what to pull for her and how she works, but I don’t know much since I’m a little dummy when it comes to figuring this stuff out lol. I basically just wanna know what her eidolons are like, how her lc affects her, and maybe her traces if it’s out yet? Any ideas or thoughts? Also I’m pretty sure I’ll play her with my Mydei, Hyacine, and Cyrene as well so I know it’s weird gameplay lol. Also is it okay to put the er planar set on her since Cyrene has the main one and effects don’t stack?
