Cirno (oswald switch)

[Mark]

Ice Sign "Icicle Fall" (tier one super offensive) (600)
She stops moving and thrusts her hands outwards infront of her body creating a bunch of ice shards the size of a .416 barrett bullet. The shards move at a speed of a man running. And they split off in two directions (giving her notorious blind spot right down the middle). She becomes fairly exhausted (like running a bit.) and she has to keep her concentration at half since she is flying.

"Icicle Attack" (300) (requires ranged proficiency, master acrobat, flight)
Cirno can create a single foot ball (American) sized icicle in each hand (to fire she has to put her hand/hands out wards and they will fire in that direction). The time it takes for this to make is about a second and they fly at the speed of a bullet. There is no actual ammo limit except if she becomes too exhausted. (the exhaustion and concentration are both like firing a gun.) The damage out  put is more like someone scratching you with a fairly old knife (not that sharp but can still harm).

Icicle Bomb (300) (requires ranged proficiency, master acrobat, flight, area attack)
Cirno will hold both hands together for a max of five seconds using half of her concentration to create a bowling ball sized "bomb" its quite exhausting like running a marathon. The bomb will explode two seconds after leaving her hands hitting a area of fifteen feet in diameter. It sprays said area with small ice shards cutting and giving off a slight cold aura (aura is fodder right now).

Icicle Fall: How wide of an area does this cover? I'm a little confused by what you mean when you say "split in two directions"; what's the angle between them?

Icicle Attack: What's the effective range on this? Can it be used while moving? Can it be used with other moves? This wouldn't require Flight or Master Acrobat.

Icicle Bomb: How fast does this move? Can it be used while moving? When you say "maximum of 5 seconds", does that mean she can throw it before that if she wants to? Can this be used with other moves? This also doesn't require Flight or Master Acrobat.
