Lightslinger is triggered and consumed by the first attack.
The second attack will prioritize enemy champions (even if hidden in fog of war or in brush) and enemy minions with low health.
Lightslinger will still be consumed if no second target is found when Lucian fires.
Lucian can move freely while firing Lightslinger since the second attack is integrated into the first one (like Double Strike) and has special movement animations depending on the direction he is moving while firing.
Piercing Light will attempt to lead the target if it is moving but does not adjust further during cast time (enemies can dodge the laser if they change their velocity by a sufficient amount during the delay)
Active: After a 0.25 seconds delay, Lucian fires a shot that explodes in a cross pattern upon hitting an enemy or reaching the end of its path, dealing magic damage, marking enemies hit for 6 seconds, and granting sight of them for the same duration.

Lucian gains bonusmovement speed for 1 second if he or allied champions damage a marked target with basic attacks or abilities.
While using The Culling, Lucian cannot use basic attacks or damaging abilities, but is ghosted, can move freely, and can activate Relentless Pursuit. The Culling can only be interrupted by crowd control that prevents the ability to use basic attacks.
The Culling can be reactivated to end its effects prematurely.
The Culling is a pair of linear, collision skillshots.
