You can't be a bad farmer with a 100% battery. Her damage kinda sucks though.

Gratz!

The good: she can Black Grail loop 1/1/X against Berserkers with the best support setup. In other words, any node composition in the game.

The bad: her damage is kind of lacking.

Overall she's very good, but not amazing.

Thanks! Well, that's good if she is good... but is there any other way to use except farmer (still not bond 15 Lancelot, so I can continue with him and double Skadi...)?

Also, it somehow happened that I already had all materials she requires, so I was able to instantly raise her:

I can see timeawise buff with 1 time evasion, debuff immunity and instant death immunity + 20% arts buff, can she be used as samy support as like David or not?

Simply lovely. I didn't see any Ruler enemy with insta death, so I don't know if she's useful or not.
