Linde with Fury or Life and death

well... attempting that she is a glass cannon, put all effort to protect her, and pontencialize her atk. L&D
Put Ardent sacrifice to open the desesperation way.

Fury is an countermeasure to avoid her to be killed, also combine with desesperation, with 2 atk decreased, 4 damage in total that you dont make with L&D.

I'd go with Fury. L&D removes her ability to take hits from Takumi, and two rounds of Fury use will put her in Desperation range if you already have that.

As someone who has both I prefer fury way much over L&D. With L&D you have to be so cautious of who she takes damage from and who she attacks and from my experience it wasn't all that great.
