Cassiopea re-rework concept

Probably shit, but I am bored, so I made something.

(With the exception of the passive, these are all adjustments to her live skillset.)

P: Aspect of Serpent Being near a champion will mark them. Poisoning a marked champion will consume the mark, causing the poison to deal 10/15/20% bonus damage. After the mark is consumed, another may not appear for 15 seconds.

Q: Noxious Blast This will be the central damage source of Cassiopea, so up the damage dealt. The skill remains the same overall.

W: Miasma The slow is lower, but is now applied "Viktor style", stacking up to 5 times. At 5 stacks, the target gains a debuff called "Chronic Ailment", which lasts 1 minute and causes all Poisons to additionally deal 25% of Miasma's per second damage.

E: Twin Fang Lower damage, but each Twin Fang strike reduces the single target cooldown of Aspect of Serpent on that target by 1.5/1.75/2/2.25/2.5 seconds.

R: Petrifying Gaze No change. This skill is great.
