Why valkyrie?

To that I would answer, why not valkyrie? She has a big pointy staby stab stab (Lancia) and a giant shield. She has consistent heals and high defensive base stats making her able to sustain for a long time and tanky.

Downsides

She has high burst damage, meaning her damage per second overall is low. Making her less optimal in spots where u need to do long consistent dps. But who cares about that when that only comes up in super end game and everyone is a flavor of the month reroller or loyal to their class at that point.

Combos

TLDR: You stab then jump onto them and swing your lancia. After that you dash in and whack your shield at them. Then the final part is simple, all you do is staby stab stab into another stab then stab swing staby stab.

Basic Infinite Combo:

Sacrum Ferit (1 Hit) > Sanctitas de Enslar > Flow: DIvina Vult > Promptness > Purificatione > Castigatio > Terra Sancta > Sacrum Ferit (1 Hit) > Verdict: Lancia Iustitiae > Flow: DIvina Vult > Blitz Stab

Keybinds:
RMB (1 Hit) > F > LMB > SPACE > SHIFT+LMB > S+LMB > LMB > RMB (1 Hit) > SHIFT+RMB > LMB > W+RMB

Combo with BSR casting speed:

Keybinds:
RMB (1 Hit) > F > LMB > SPACE > SHIFT+LMB > S+LMB > LMB > RMB (1 Hit) > SHIFT+RMB > LMB > W+RMB > S+LMB > S+E / SHIFT+X > F > Space

Addon:

*Some may noticed that valkyrie has a 100% crit rate most of the times, however having that 20% on castigatio helps with dps so you dont have to use RMB so much and lose your dps.

After the new addon updates the addons are subject to change but this will serve as a good starting point
