Nocturne's Curtain Call (Columbina's weapon) Lvl 1 vs Lvl 90. What is the main difference?

Neuvillette got all 3 stacks for his A1.

Took more Neuvillette's hair to level up.

I like lvl 1 more

It’s brighter and you can see a bit more detail in the circle ( *lvl 1 just has dots and lvl 90 has dots and lines* ).
