Active:Nocturne sends out a shadow blade in a line that leaves a Dusk Trail on its path, dealing physical damage to enemies it passes through and causing enemy champions hit to also leave a Dusk Trail behind their movement for 5 seconds.
Duskbringer's Dusk Trail will 'reveal' the path of affected units until its duration ends. This means it can indirectly show the location of any affected units without vision on them, including those in stealth.
With the bonus AD from the Dusk Trail, the effective base damage is 71.25 / 123.5 / 176.25 / 228.75 / 281.25
Passive:Nocturne gains 335 bonus movement speed when moving toward fleeing targets.
Active:Nocturne plants nightmares into his target's mind, dealing magic damage over 2 seconds and forming a tether between him and his target. If the target does not break the tether by moving out of range, they are made to flee from Nocturne for a short duration while slowed by 90%.
