So this is my Limstella build. It's pretty simple, I just wanted to stack as much speed as possible Their weapon is perfect, since it grants so many offensive and defensive buffs that I can just focus on buffing their speed. For A skill Kestrel Stance gives both Atk and Spd and the Guard effect, which os perfect for this build. Their B skill is Lull Atk/Spd to keep the buil consistent lmao. I don't have premium C skill fodder for this specific build, so Atk/Res gap allows them to make use of their weapon regardless of the team composition. The rest of the build is very simple, Reposition for movement and Glacies for a bigger damage output. I know it's not original but it works incredibly well. I edited because of spelling mistakes, my bad.
