Aeroblades

The Aeroblades are a powerful group of weapons created from Deepstone found at the bottom of the Endless Ocean. The Ninja obtained the Aeroblades, anticipating to use them against the Ghosts after getting them from Ronin. They have the ability to defeat ghosts when slicing through them.

Appearance and Abilities
The Aeroblades resemble a shuriken-like weapon that are usually dull and non-colored. However, when touched, they glow in bright colors, usually depending on the person’s element, which allows the weapon to have the ability to defeat the Ghost Warriors when they come in contact. The Aeroblades are circular in shape with three sharp points on their sides.

The Aeroblades can also be used for battling enemies that are not ghosts, being used as regular weapons. The Ninja and Ronin have used their Aeroblades as shurikens, and they are large enough to be used against other weapons in melee combats, just like shurikens also.

Stiix and Stones
When the Ninja confront Ronin in his shop in search for the Scroll of Airjitzu, he misdirects them towards buying weapons from him, which leads him to offer them the Aeroblades, but at a price they can't afford. Later at night, they attempt to steal the scroll from his shop, and are confronted by Morro and multiple Ghost Warriors. The Ninja and Ronin used their Aeroblades to battle the ghosts while everyone battles to get the Scroll of Airjitzu.
