Spring Camilla Weapon

The egg imo is worthless and she is ways better with either Gronnblade+ or Gronnraven+.Still,since yours is -att,I believe the only ways to really use her is tough buff emblem with gronnblade+.Still you should wait for more answer,some people might have better tips than me.

Gronblade.
She's -Atk, so she wont be able stand up to blue units with doubling speed, like Linde, Delthea, and Lute.
