Skarner

Innate: Skarner's basic attack on-hit, Shattered Earth, Upheaval, and Impale apply a stack of Quaking to enemies hit for 4 seconds, refreshing on subsequent applications and stacking up to 3 times. Enemies afflicted with 3 stacks take magic damage equal to % of their maximum health over the duration, capped at 100 to 450 for 15% against monster.

Active: Skarner rips a boulder from the ground, empowering up to three of his next basic attack within 5 seconds of each other. These attacks gain bonus attack speed, and deal bonus physical damage to the target and surrounding enemies, including structures.

The final attack slams the boulder, dealing an additional 11% of each target's maximum health physical damage and slow afflicted enemies by 45% for 1 second. The additional damage is capped against monster and is not applied against structures.

After 0.5 seconds of the cast, Skarner gains the ability to use Upheaval during Shattered Earth.

Active: Skarner slams his claws into the ground, shield himself equal to 10% of his maximum health for 2.5 seconds and releasing a shockwave that quickly expands in a radius around him to deal magic damage to enemies hit and slow them by 25% for 1 second.

Skarner can move during Seismic Bastion's cast time.

Active: Skarner charges forward in the direction of the cursor for up to 2.75 seconds, during which he gains slow-immune, becomes ghosted, ignores terrain collision, and has unobstructed vision of the surrounding 650 units. He automatically navigates his movement along the way and is able to steer himself with a slow turn rate that increases over time, resetting upon changing direction. Ixtal's Impact can be recast after 1 second, and does so automatically after the duration.

Skarner begins the charge at a static amount of 150 movement speed that increases by 100 every 0.25, up to 950 total movement speed by the end of the duration. If Skarner collides with an enemy champion or large monster, he grabs them with his claws for the time of the remaining charge, attached them to himself, suppression them, true sight them, increasing the charge's turn rate to the maximum, and gaining 300 bonus movement speed, with a minimum total of 650 and a maximum total of 1150. If a target has been grabbed before the first 1.75 seconds of the charge, the remaining duration is set to 1 second, and set to 0.5 seconds otherwise. The charge does not ramp up in speed while a target is grabbed.

If Skarner's attached target collides with terrain, the charge ends, detaching them from him, dealing physical damage, stun them for 1.5 seconds, and reducing Ixtal's Impact's cooldown by 35%.

Active: Skarner winds up his stingers over the cast time, then lashes them forward in an isosceles trapezoid in the target direction, dealing magic damage to enemies hit and impaling up to 3 of the closest enemy champions within the area to suppression them for 1.5 seconds. While suppressed, the targets are true sight and attached to Skarner. If he successfully impales at least one enemy champion, Skarner gains 40% bonus movement speed for the same duration.

If Impale is cast during Shattered Earth, Skarner automatically casts Upheaval in the direction of Impale's cast. Skarner is unable to basic attack, cast Shattered Earth or Ixtal's Impact, or use Flash during Impale. While the targets are impaled, they are attached to Skarner 300 units in front of him. Targets are placed 200 units in the same direction at the end of the effect.
