LeBlanc, the Deceiver
Right of the bat. I tried to turn her from an assassin to a control mage but don't worry I kept some of her mobility. So please have an open mind.
(Passive) Mirror Image (Static cooldown: 30 seconds)
When LeBlanc damages an enemy champion with one of her abilities she turns invisible for 1 second and creates a clone of herself right on top of her that remains for 8 seconds or until killed. This clone uses the same ability LeBlanc used to activate this passive. This clone also attempts to mirror LeBlanc's movement and abilities, using the shortest way between LeBlanc and the nearest enemy champion as the axis of reflection. Otherwise the clone can be controlled via ALT + RIGHTCLICK.
(Q) Black Roses (Mana cost: 40/45/50/55/60; Cooldown: 7/6.5/6/5.5/5, starts after the last rose is thrown or 3 seconds after none is thrown)
(Active) LeBlanc throws up to 3 razor sharp black roses in a sraight line in target direction that each deal 25/40/55/70/85 (+20% AP) magic damage to all enemies hit (minions receive 50% additional damage) but stop at enemy champions. Between throws there is a 1 second cooldown. Dealing damage to a champion grants her 10% movement speed for 1.5 seconds. Enemies hit by one are slowed for 15%/17.5%/20%/22.5%/25% for 1.5 seconds. If they are hit by two the slows effectiveness doubles. If they are hit by all three the enemy is stunned for 1.1/1.2/1.3/1.4/1.5 seconds and receive 30/55/80/105/130 (+25% AP) additional magic damage.
(Cast time: 0.5; Range: 1000; projectile speed: 2500; path is indicated during the cast time, similar to Jhin's and Jinx's W)
What I was aiming for: I felt like "Sigil of Malice" was very uninspired and has nothing to do with LeBlancs character. Those who know LeBlanc's lore will know about the "Black Rose" and I wanted to put it somewhere in her kit. Now its her main damage, harass and waveclear tool.
(W) Distortion (Mana cost: 65; Range: 600; Cooldown: 20/17.5/15/12.5/10)
(Active) LeBlanc dashes to the target location, dealing 70/105/140/175/210 (+50% AP) magic damage to all nearby enemies upon arrival and leaving a return pad at the cast location for 2 seconds. After 0.2 seconds she can recast Distortion at no additional cost in order to blink to the return pad.
(Passive) Using other abilities while a return pad is on the field extends its duration by one second each (every cast of "Black Roses" counts but only the initial cast of "Mirror, mirror...").
What I was aiming for: "Distortion" still fuctions pretty much the same but the time that LeBlanc has to return to her return pad is significantly reduced if she uses it defensively and deals less damage overall. In return for the lower damage and duration I also significantly lowered the mana cost on higher ranks to keep her mobile for a lower cost.
(E) Mirror Cabinet (Mana cost: 75; Cooldown: 24/22/20/18/16; Range: 650)
LeBlanc erects 6 mirrors in a hexagonal pattern at the target location for 5 seconds, creating terrain which can be passed by allies but not enemies. Every mirror has 2 health and can be damaged by auto attacks or instantly destroyed by dashing through them. If an enemy dashes through them they receive 75/120/165/210/255 (+35% AP) magic damage. Furthermore these mirrors obstruct vision. Throwing "Black Roses" through a mirror or dashing through them with "Distortion" increases the respective abilities magic damage by 35/60/85/110/135 (+40% AP) but decreases the respective mirrors health by 1. Allies inside the cabinet are invisible to enemies outside it as long as all 6 mirrors are intact. Recasting the ability destroys the mirrors.
What I was aiming for: I always thought it's a bummer that LeBlanc doesn't use ACTUAL mirrors in her kit. Instead of "Ethereal Chains" (which also feel uninspired) she now has a huge utility tool with "Mirror Cabinet" which is a mix of Akali's "Twilight Shroud", Veigar's "Event Horizon" and Yorick's "Dark Procession" which can also increase her damage. I'm still not sure how big the cabinet should be though.
(R) Kaleidoscoup [as in kaleidoscope + coup] (Mana cost: 100; Cooldown: 140/120/100; Range: 1000)
(Active) LeBlanc marks an enemy champion for 10 seconds. While the mark is active the champion receives 20%/35%/50% increased damage from LeBlanc and gives additional effects to LeBlanc's basic abilities:
Black Roses: The amount of roses doubles, the cooldown in between throws is halved and they inflict greavious wounds for 2.5 seconds if thrown through a mirror.
Distortion: The cooldown is reduced to 1 second and the mana cost to 10 and but only one use within the duration of "Kaleidoscoup" can deal damage to enemy champions.
Mirror Cabinet: The ability is cast immidiately onto the marked enemy regardless of the distance to the target, mirrors no longer are damaged by LeBlancs other abilities and enemies attempting to dash through mirrors still shatter them but stop dead in their tracks and are stunned for 1 second.
(Passive) If LeBlanc manages to kill or assist in a kill of a marked target she gains the ability to transform into this champion when out of combat for at least 5 seconds, copying all abilities, stats (except for health and stats which LeBlanc's exceed those of the chosen champion), items and masteries. This can be done by choosing the respective champion's icon from a list similar to that of Kindred. When transformed, the list turns into an icon of LeBlanc, which can be clicked to turn her back into her normal self. The transformation converts 33% of LeBlanc's max. health into a shield. If this shield is destroyed LeBlanc turns back into her normal self. The shield is also destroyed when manually exiting the transformation (cooldown: 45 seconds after shield-destruction/10 seconds after manually exiting the transformation).
Additional Info: Simply marking the enemy with your ult isn't supposed to grant an assist. If the targeted enemy dies without LeBlanc assisting in the kill, the ult is put on a reduced 15 seconds cooldown but no mana is refunded.
What I was aiming for: And now for the most uninspired ability in the entire game so far (which is "use one of your abilities a second time") and MY "pièce de résistance" of an ult if you will... or dont. At first it seems like a glorified Zed ult of sorts with empowered basic abilities. But the real thing is the ult's passive, which takes huge inspiration from LB's lore.
In the now lore (which coincidentially came out today!) she takes on the appearance of someone else but it seems that she (or anyone) has to kill this person before being able to take on his/her appearance (though that isn't 100% clear) and even in the old lore there was the conspiracy that Jarvan IV was actually LB in disguise. And that is exactly what I wanted to go for with her new ult. Though completely copying almost everything maaaaay have gone a little overboard. Tell me what you guys think about that.
All ratios are open for debate of course. I tried to make them balanced but I'm not very good at that.
