Barblade or Aura Refine

Blarblade is probably the best choice for an offensive Linde, but it is expensive. The Aura refine is more suited for a support Linde, but requires Divine Dew.

I also have a +Spd Linde, and I personally prefer to run Aura refined or Dark Aura because I find Blarblade quite boring on units with Proficient weapons and because she has a really cool niche of being a Tome unit that can buff the Atk of either Physical or Magic units (if you don't have Atk Tactic).

But, this is just my opinion, so you don't have to follow it if you don't like it. If you have the feathers, by all means, go for Blarblade+. If you want to spend Dew, then the refines are great. It depends on how you want to play when using her.

I also have a +spd linde and run blarblade on her only because I plan to give her even spd wave/odd atk wave to make her a self buffer. I would personally go with a blade tome set, but it is much more premium compared to a refined aura build.
