-atk +res Linde

Yeah, she's easily the best blue infantry blade user with her spread of 35/36 Atk/Spd. The -Atk is unfortunate, but she's definitely usable!

She'd be on par with Nino if it wasn't for the fact that she's a 5* exclusive.

Also, she has access to Dark Aura so she could make a good support unit if you feel she'd be better with that.

She still is great Blade tome user, otherwise you can get Dark aura on her and have nice offencive and supportive unit. She might come in handy for arena assault.
