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.

If you're using an Arts team against a boss with Instant death she's definitely a good support option. It's kind of awkward because you have to use her battery the same turn as the 3rd skill to guarantee it and they have different cooldowns so after the first time it won't line up right. I'd prefer using Skadi or Ereshkigal against instant death, but Nito alter would be among the best options. You also could use her to enable anti evil SE multipliers, but that would be a very niche thing to do. Farming is by far her most common use though.

Okay, thanks that's quite useful info!
