Underthrow Freeze Sinker

is the Noble Phantasm of Anastasia & Viy in their swimsuit. 
The Grand Duchess uses her killer underhand throw to seemingly lob a nice, soft snowball at her target. It is, however, a lump of tightly compressed ice disguised by powdery snow. By putting a little spin on the throw, she's able to give it far more destructive force than would seem possible. That alone would make it hard to deal with, but Viy's Mystic Eyes enable it to curve in flight while retaining the full force of a fastball.
This Noble Phantasm is, as a rule, not used in FGO. Probably.
