Ekko Ability (LoL): Timewinder

Ekko throws a device in a target direction, dealing 60 / 75 / 90 / 105 / 130 (+30% of ability power) magic damage to all enemies along its path. At maximum range or if it hits an enemy champion, the device slows to a stop and expands, creating a slowing field which slows enemies inside it by 32 / 39 / 46 / 53 / 60%.

After a short delay, the device contracts and rushes back to Ekko, dealing 40 / 65 / 90 / 115 / 140 (+60% of ability power) additional magic damage to all enemies along its path.
