Does halp serafi get a boost with serafi-senba?

[SnowfoxZero]

Highly doubting it, but technically speaking it SHOULD if daggers of serafi does. Want to know before I front the meseta to buy one.

i don't know if that weapon is getting any bonus from
the armor, but Dagger of Serafi does get
bonus from it.

It's the same theory behind Storm Line. Storm gets a bonus, but the Twin variant? Pfft.

[McLaughlin]

Nope. Dagger of Serafi does, but Halp Serafi doesn't.

The set isn't even worth it to begin with. I wouldn't waste your time with it.

Halp Serafi (and Twin Tornado) don't get a boost.

There's tons of examples where the single weapon is affected and the twin version is not, or vice-versa.
