Ah ok, thought it might of. The pre-reg pulls go by so fast I probably wouldn't have even noticed if I hadn't drawn Artemis.
who is the best SR princess?
As far as i heard - Belphegor.
I rolled a Fafnir...Do you guys think it's worth it to replace my Takemikazuchi?
In a word: Yes.
Even if you don't specialize in fire(or water), Fafnir is still one of the most useful summons in the game - in my subjective opinion. She does great damage, provides nice passive boosts, and also buffs everyone when she is summoned.
(PSA: This gets covered nearly every page of this thread.)
