C rank is already a very low rank, Deadly Sphere Staff is bad but at least it functions. It's aerial, knows the concept of going after an enemy and attacking it from what I saw and has solid base damage. Again IT IS very bad, but it's not outright depressing like the Pirate Staff is. In general the description for C-rank fits Sphere perfectly: Overall bad and outclassed, but still USEABLE and not too horribly clunky. It's not something like Platinum Shortsword, Slap Hand or Pearlwood Bow in term of combat abilities.The cells fire extra shots at enemies you are attacking with another weapon. That's what you see here, it's intentional behavior. Besides that, I think it's just Xeno Staff AI.
Ok so its only use is being slightly stronger than an Early Hardmode minion (a busted one, but early hardmode nonetheless) except that it doesn't matter that much because Iframes and worse AI mess it up.
Yeah no this honestly deserves D as well. Availability is another thing against it, Deadly Spheres are relatively uncommon and the time spending farming Solar Eclipses could just be spent AFKing in a desert killing Mummies for the Tiger.
A lot more whips are included now. Will add the rest later.
