Announcement made in the sneak peak by ByronicHero:
If you’ve been looking to add a little bit of high society to your League of Legends lineup, this next patch is the one you’ve been waiting for. Allow me to introduce the talented and graceful LeBlanc, a stately sorceress ready to round out your champion selection. In addition to being extremely attractive, the Deceiver comes primed to fuel your most megalomaniacal of desires. If you've got a bit of mischievous thread to your personality, you're definitely going to want to make sure to pick up LeBlanc in the upcoming patch. Would I lie?
Sigil of Silence: LeBlanc projects an orb towards her target, dealing magic damage and marking the target for 3.5 seconds. If the target takes damage from one of Leblanc's abilities, the mark will trigger, dealing damage and silencing the target.
Distortion : LeBlanc rapidly moves to a target location, dealing magic damage to nearby units. In the following 3 seconds, she can activate Distortion again to return to her starting location.
Ethereal Chains : LeBlanc flings illusionary chains towards a target location. If it hits an enemy unit, it will deal initial magic damage and slow their movement speed by 25%. If the target remains shackled for 2 seconds, the target takes additional magic damage and is unable to move.
Mimic (Ultimate): LeBlanc can cast the previous spell she cast. The mimicked spell deals significantly increased damage. 30 second cooldown.
Mirror Image (Innate): When LeBlanc is brought below 40% health, she instantly becomes stealthed for half a second. When the stealth fades, she creates a Mirror Image that deals no damage and lasts for up to 8 seconds. This can only occur once per minute.
