Thread: blitz weapon, eidolon, or both?

Assuming this is Yatagarasu, as I'm not sure why you didn't just post in there, the eidolon is more important. The attack down debuff is more valuable than 1 SSR weapon, even if you us fire. 1 SSR weapon is unlikely to be the deciding factor to whether you win or lose as long as your weapons in general are leveled, while Yatagarasu's debuff can be. Regardless, you'll get another chance to max them again in the future when we get a rematch event.

If you re new then you definitively want to go for the eidolon. Even if it was a really good weapon as you evolve your account you will end up with a lot of different souls that might not be able to use the weapon, vs the eidolon which is way more versatile since you can use her in any team because of her effect.
