Add a new form of CC. Paralysis.

Paralysis is applied to a new item (to be available to many characters) instead of a new champion, because one champion is not going to make much difference.

Bilgwater cutlass + [Something] = Lightening Katana(or whatever name)

[Bilgewatery cutlassy and the other itemy stats]

Active: Applies paralysis to target enemy champion for [longish duration], Paralysis stops a champion from using blink or dash abilities (anything they couldn't cast while snared).
