Abilities 
Passive - Miasma A thick, black cloud seeps out of Malice as she breathes. The cloud surrounds her enhancing her next basic ability. The cloud lasts 6 seconds, and comes back every 24 ( Level 1) - - 18 (level 9) - - 12 (Level 18).
Enhanced Effects
Black Kiss - Instead of silencing, black kiss will stun for 1.5 seconds.
Deaths Breath - Extends the width and length of the cone, while also speeding up the channel time.
Asphyxiate - If the beam is broken, or a full channel is completed on an enemy champion, they will be cursed with her miasma, causing them to choke for (3/6/9/12)% of their max health over 4 seconds.
Q - Black Kiss: Malice sends forth a smokey blast from her mouth, silencing and choking the first enemy hit.
(Range, damage, and scaling is equal to that of Ahris Charm 
)
W - Deaths Breath : Malice stands still and channels deaths maw out of her mouth. She sucks life out of all targets hit in a cone, slowing them if their back is turned to her. Enemies that take the full effect channel of deaths breath are hit for bonus damage based on the amount of health they are missing. Malice gains back 10% of the damage dealt to targets hit by this ability as health. (30% effective on minions) (80/160/240/320/400)) + (20% of AP)
E - **Asphyxiate **: Malice channels a smokey beam from her hand to an enemy champion. The beam chokes the target over time for (35/55/75/95/115) (+30% AP). The beam can be broken by running out of range.
(Think of Karmas W!) 
R - Miasma : Malice summons a wide fog of miasma that increases in density over time. The miasma slows and damages all enemies inside. The damage and the slow increase the longer the enemy stays inside the miasma. Miasma lasts for 9 seconds. (50/100/150) at start - - 3 seconds with a 30% slow (100/150/200) - - 6 seconds with a 50% slow (150/200/250) - - 9 seconds with a 70% slow
Walking Animation
She does not walk by foot, her animation will be similar to Syndra 
, as she will float along a small cloud of smoke (that will look differently from her passive so players will not get confused as to when to avoid her passive for counter play)
Ability Animations
Black Kiss : She will simply, quickly put a hand up to her mouth and blow the kiss forward.
Deaths Breath : She will stand still, a dark/spiritual mouth will appear over her face, and she will lean forward as she sucks in the life of those in front of her.
Asphyxiate : She will stick one hand forward as the beam protrudes from said hand, creating a cloud around the enemy champions head, choking them.
Miasma : She will slowly raise both hands from waist level, up to her chest, as if she is telling an audience to rise. The miasma will then appear from the ground.
Quick Facts
Age: Unknown
Eye Color: Glowing white
Hair: Her hair looks as if its made of long black smoke.
Clothing: Flowing black cape embellished with white around the edges.
She is barefoot as she floats. She has no pants, but her 
is covered by a long black smokey half-robe.
She has short smokey claws that appear over her fingers.
Strategy
Think of her a bit as blend between Ahri, Swain, and Karma. 
She is fairly weak before level 3, as her abilities will work as a combo. She is mostly glass cannon, but can be built to be a tankier APC (Rod of Ages, Rylais, Zhonyas), or even a support building Spellthiefs Edge first.
In mid lane, it would be best to just farm CS until level 3. Once your combo is available, try to land an enhanced Black Kiss, into a Deaths Breath, and then chase them down with Asphyxiate, and possibly finish off with ignite.
As for late game, expect to sit in the mid-line of your team, waiting for an engage on either side. If your team engages, prepare to cast an enhanced Death Breath and slow / damage as many as you can, while also landing a Black Kiss for CC.
If it is your team that is engaged upon, use Miasma to intimidate the enemy, and possibly turn the team fight.
Playing AGAINST Malice Honestly, the tips are pretty simple.
Dodge her Black Kiss, especially if it is enhanced.
As she winds up for Deaths Breath, prepare to step to the side or to go all out on her as she cannot move while channeling.
If you are being Asphyxiated by her E, just run out of the range, or finish her off before she can you.
