Welp, I ended up also deciding to get the guaranteed SSR Eidolon gacha, too. Got yet another copy of Takemikazuchi, bringing her up to 3 stars. But I also got my very first 100% Eidolon...Hraesvelgr! Wouldn't you know it, even when I have good luck I have bad luck, because my Wind team is by far my worst so that was the least helpful 100%er I could have gotten. Still nice, but not half as nice as it could have been.
