Aatrox swings his greatsword in the target direction, striking enemies in a line. The Darkin Blade can then be reactivated twice within 4 seconds, with the second cast refreshing the timer. The second cast strikes enemies in a cone and the third in the target area.

The first cast deals 10 / 30 / 50 / 70 / 90 (+0.6 / 0.65 / 0.7 / 0.75 / 0.8 per attack damage) physical damage, increasing by 25% on the second cast and 50% on the third. The Darkin Blade deals 50-100% (based on level) damage to minions.

Hitting enemies at the far end of the first two casts and the center of the third deals 50% bonus damage and knocks up enemies for 0.25 seconds. Monsters are knocked up for 0.5 seconds instead.
