Cassiopeia rework Idea concept thingy

(P) Deadly Cadence: Auto attacking and damaging enemy champions with spells grants stacks of Deadly Cadence on-hit (Half stacks for auto attacking). At maximum number of stacks, Cassiopeia enjoys reduced mana costs on her basic spells for a short duration.

(Q) Noxious Blast: Cassiopeia throws poison at the target area after a short delay which poisons enemies. This spell has a sweet spot (Think Soraka Q) which deals 150% damage and grants Cassiopeia a movement speed buff (Minions don't take extra damage from the sweet spot and do not grant Cass bonus movement speed)

(W) Miasma: Cassiopeia throws a pool of poison that slows and damages enemies walking through it. Enemies that leave the pool carry around a trail of poison that damages enemies walking on it and increases Cassiopeia's movement speed.

(E) Viper's Kiss: Targeted projectile that deals a small amount of damage but increases the damage of poisons affecting the target by a percentage. That percentage stacks up to a cap. Viper's Kiss refreshes it's cooldown on-cast against poisoned enemies.

(R) Petrifying Gaze: Cassiopeia stuns and damages enemies facing her in a cone. Enemies not facing Cassiopeia are slowed and take half damage. Enemies killed while petrified explode, dealing damage and applying Miasma's poison in an AOE around them
