Linde -spd/+atk

Desperation is great, but personally, I say Life and Death. That's a permanent +5 to both Atk and Spd. Even if she's just at 38 speed with it, that's still pretty fast and can outrun quite a bit of other units. What type of weapon you wanna put on her could also factor in which A skill you would want. Do you wanna stick with Aura or switch to Robin(M) or Odin's weapon? It's really personal preference, but I say Life and Death.
