Noir's new spell

Tier: A
Class: Magician
Type: Offensive
Range: Long
Requirements/Drawbacks: Noir has to draw circle with her staff/wand and mention the spell name before using
Scaling: Hits
Sustain: 0

Description: Using destruction magic, Noir is able to create a small black sphere, 1 cm in diameter. This black sphere is created from a boiled water which was compressed with strength magic into an incredibly small size black sphere. The sphere will be launched up to 20m from Noir and will explode on contact, making an 8m rapid explosion the form of steam and force, dealing A-tier damage. It will send the victim flying backwards 1/4th the distance of its own blast radius as the side effect.

For the most part this ability is looking great, I just feel for the requirement you should include something about concentration. It's a strong A-tier ability so something to indicate it's not instant as soon as your staff is up and you just think it. Also the size seems to 8m but it feels a little vague, maybe word it to say it's an explosion 8m in diameter.
