Unleashing a wind bomb

"How are you doing this?" Vincent asked at the familiar scene before him. After reading too many stories, Vincent felt nostalgic by the sphere of mana, wind, or energy spinning between her hands.

Ester looked at Vincent and lost her concertation. The sphere suddenly spun at a different speed and went off course, causing it to jump from her hands and fall...

*Boom*

After the sphere of compressed wind with mana inside touched the ground, it dug a few inches inside the earth. After the wind started getting mixed with different contents, the sphere suddenly exploded. Soil and grass flew everywhere, and a small cloud of dust covered most of their view.

*Cough, cough* "Is everyone uninjured?" Vincent asked, coughing from the cloud of dust.

"I am okay... but a little soil entered my, my, my..." *Achoo!* Lupa loudly sneezed.
