I finally got my Svarog from MT and in the process to max her level. I know she is definitely one of the himes you want to get full 5 slots on acc. The other fire SSR himes I have are Ares AW (4 slot), Mars, Amaterasu, Prometheus, and Yamaraja. Should I attempt to unlock any of these hime's slot and should I just unlock Ares's 5th slot or save the materials till I get someone better like Uriel.
