Official Move Approval III

[Strazio Rockwell]

Celestial Brush: Cherry Bomb - Requires Area Attack Proficiency
Expected cost - 300?

Amaterasu uses the magic brush that is at the end of her hair, turning the very world before her into her canvas. She draws a circle into the air, while saying "baku" (japanese noun, meaning "explode"). This creates a large spherical Cherry Bomb with fuse, around one meter large, at the location she was drawing at - this can not be further away than three meters from her. The Cherry Bomb itself is completely wrapped into what looks like wrapping paper - it's very colorful, which makes it look more like a carnival firework than an actual danger.
The bomb lasts for ~5 seconds during which the fuse burns out. During that time it acts as a solid object - it can be pushed around and would roll down uneven terrain. However its large size makes it rather unhandy. After the five seconds, the bomb explodes into bright fireworks, smoke, confetti and a strong scent of gunpowder, dealing damage up to four meters from its center (so - that's not the bomb's size plus four meters, only four meters total). The fireworks also form the kanji 華 (kabi, shiny/flashy) for ca. 1 second. That is a cosmetic effect that does not influence the move. While the bomb is rather powerful its long duration before it explodes means that it is more useful to create an area of denial or to hit stationary targets.
It should also be noted that only a single bomb can be "active" at a time.

Can the fuse be severed to stop the explosion? Also this would need ranged materialize proficiency (And ranged proficiency, but I think you have that). 300 OM is fine, unless you want to do something like drop it on top of people's heads to concuss them.
