Yes. But to be fair, all servants greatly benefit from having NP2 or more.

NP2 is the biggest upgrade anyone can get. It increases the power by 50%.

After that NP5 is the next biggest upgrade for obvious reasons :p

Let's not forget NP1 is still the biggest upgrade any servant can get cause you get servant for the first time XD

True haha

When you think about it, NP1 is a 100% upgrade (yes I know that's the point of the joke)

But I was thinking about her skill 3 in super aoko form, and because it's a flat -100% gauge, there is a world where you can still save something if she has access to 200% or 300%. Not that I think it's absolutely necessary outside of CQ because the fights would usually be over before you need any of that to happen, but that's something :')
