MLB Sylph(r) (wind analog of cat) in compartion to Behemoth lb0 has a) less raw stats b) weaker skill modifier c) no cleance on skill so i used it as fodder because of her total uselessness and i think that it was a mistake to level her up (non-ssr eydolons worth keeping are disaster sr and Vine, maybe Anzu). So i still say that Hastur/Gaja/Ctulhu/Ryu-Oh/Sol/Michael + Behemoth is already a good starter account, while just Behemoth herself is not enough. Other ssr gacha eydolons (not Belial/Hraesvelgr/Rudra or at least Behemoth+ good ssr hime ) worth nothing.
