Umbrella Storage

Like any other technique, There were disadvantages and advantages.

Its disadvantages were Short-Range, Low Damage, and loses its optimum power and speed once it travels past fifteen meters. 

But its advantages were high speed, tracing, sure hit as long as opponent within fifteen meters, and low cost of order force.

Despite being a 2-star technique, Its cost of using order force was the same as Sumireas Slash.

Of course, These advantages and disadvantages only applied to the first level of Skyline Blow.

The Skyline blow had four levels, and each level up makes it more powerful.

When Athan learned the first level of Sumireas Slash, It took him eight hours.

But he took two whole days before he fully learned the first level of Skyline punch.
