Skarner's presence causes crystals to spawn in set locations around the map. While near crystals his team owns, Skarner gains tremendous movement speed, attack speed, and mana regeneration.
Q - Crystal Slash
Skarner lashes out with his claws, dealing physical damage to all nearby enemies and charging himself with Crystal Energy for several seconds if a unit is struck. If he casts Crystal Slash again while powered by Crystal Energy, he deals bonus magic damage.
W - Crystalline Exoskeleton
Skarner gains a shield and has increased Movement Speed while the shield persists.
E - Fracture
Skarner summons a blast of crystalline energy which deals damage to enemies struck and slows them. Basic attacking these enemies within a short window will stun them.
R - Impale
Skarner suppresses an enemy champion and deals damage to it. During this time, Skarner can move freely and will drag his helpless victim around with him. When the effect ends, the target will be dealt additional damage.
