This one could pair well with the Bladesaws Hatsu I made.

Name: Guard Breaker

Type: Transmutation

Ability: The user forms a cone with a spiraling edge (in essence, a drill), which they then spin after giving it the properties of metal or another hard material, like diamond. This way, the user is capable of increasing its piercing power to drill or pierce through almost anything.

Limitations: spinning the 'drill' will cause a slow drain on the user's aura, with higher rates of rotation and higher piercing power requiring more aura.
