You have to revert the passive back to its original of Deadly Cadence because of the fact she is a spammy mage in nature who is aggresive, she isn't suppoed to sit idle and farm for hours. She is the Champion that has to take the mid lane role, if her team needs help she has to be there for the midgame and the rework doesn't accomplish.
It really hurts her.
So here is a rework concept:
- Revert passive to the Original of Deadly Cadence
Q: Noxious Blast (Active): After a brief delay, Cassiopeia blasts a small target area with an explosion of poison. All targets hit are poisoned and dealt magic damage over 3 seconds. Cassiopeia is granted a movement speed boost for 3 seconds if she hits a champion with the spell. Upon hitting a champion with Noxious Blast, the enemy is inflicted with Noxious poison that deals xx magic damage over 5 seconds. Noxious Poison stacks up to a maximum of 5 times.
If the target has "Embedding Fangs" stacked, the following effects will occur if Noxious Blast successfully lands:
2 stacks: Noxious Poison starts at 2 stacks
4 stacks: Noxious Poison starts at 2 stacks and explodes another Noxious Blast zone in a larger radius after the first Noxious Blast
6 stacks: Noxious Poison starts at 2 stacks and explodes another Noxious Blast zone in a larger radius after the first Noxious Blast and slows anything in the radius for 1 seconds
8 stacks: Noxious Poison starts at 2 stacks and explodes another Noxious Blast zone in a larger radius after the first Noxious Blast and slows anything in the radius for 1 seconds. From the explosion, projectiles are launched in random directions and land to create mini Miasma pools.
All stacks of Embedding Fangs are consumed with this ability.
Cooldown: 3 seconds
Delay: 0.6 seconds
Range: 850
Diameter of AoE: 75
W: Caustic Miasma (Active): Cassiopeia throws a growing cloud of poison to a target location. The area lasts for 4 seconds and provides vision over it for the duration. Any enemy that passes through it is poisoned for 2 seconds that is renewed by continual exposure. Poisoned enemies receive magic damage each second and are slowed. Caustic Miasma gains a charge every xx seconds up to a maximum total of 2 charges. If Caustic Miasma lands on a target inside a small target circle, the enemy is debuffed with "Corrosive" which reduces magic resist and is poisoned overtime. This effect does not occur if an enemy walks on the Miasma pool.
Cooldown: 6 seconds
Range to Center of AoE: 850
Diameter of Aoe: 100-175
Diameter of center reticule for Caustic debuff: 50
E: Merciless Nails (Active): Cassiopeia deals magic damage to her target and stacks "Embedding Fangs" each hit on the target. Cassiopeia is granted a movement speed boost for 2 seconds when she hits a champion with this spell.
If the target is inflicted with "Corrosive" , each Merciless Nails renews the duration of "Corrosive" by 1 second up to a cap.
If the target is poisoned when hit then Meriless Nail's cooldown is reduced to 0.5 seconds. This ability does not reset on Noxious Poison.
Cooldown: 5 seconds
Range: 700
R: Petrifying Gaze (Active): Cassiopeia deals magic damage to all enemies in a cone in front of her. Enemies facing her when damaged are stunned for 2 seconds, while enemies facing away are slowed by 60% for the same duration.
Range: 850
Cone Angle: ~83º
Atleast now there are interactions between all the abilities and have a concept to how it would combo with each other.
