Here at PAX East, everyones Eternal Nightmare is the talk of the town. We just completed our demonstration of Nocturne and his groundbreaking new Near Sighted mechanic.
Nocturne is an assassin type character who functions very differently than the traditional archetypes. Unlike a traditional stealth character such as Twitch who becomes personally invisible, or a character such as Nidalee who has special synergy with the brush, Nocturnes ultimate ability afflicts the entire enemy team with a specialized debuff. This ultimate dubbed Paranoia removes the players shared vision with allied units, leaving them blind to anything beyond the sight range of their own champion. In this way, Nocturne is able to sow confusion amongst the enemy team, striking quickly and taking down enemy champions while their allies are blind to their need for assistance.
