[Rust Storm]. It is an evolution of skills like [Gust Blast], but it can only be obtained by those who have the [Rusty Wind Technique User] title, or the titles that are advanced versions of it.

This skill is an attack skill that consumes MP to release a powerful wind that contains rust particles at a target. While the wind itself has a high attack power, the rust particle can be fatal to equipment, as they tear the durability and other abilities of said equipment if they are exposed for too long to the rust. 

In addition, skilled users of this skill can even alter how the skill takes shape. They can use it as a single spear of wind, cover a whole area similarly to a sandstorm, or even enhance other Wind-type moves with the rusty winds.
