No they don't. Claws have the same drop rate as any normal magna SSR weapon.
It's the exact same. Who told you the drop rates were different? Was it reddit?
Did you have a stroke or something? I'm talking about Celeste claws.
My advice is to go back to cuckchan and stay there. Out of those three you should stone Varuna. But it'd be best to just wait for the anniversary to see what magna II is before you do anything.
I forgot to mention that this could easily be fake.
