The damage type that Skarner deals is mostly Physical Damage.
Skarner's damage type breakdowns as follows:
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.
Skarner slashes wildly, causing all nearby enemies to take physical damage equal to 33/36/39/42/45 plus 1/1.5/2/2.5/3% of their maximum health. If a unit is struck, he charges himself with energy for 4 seconds, causing Crystal Slash to strike twice and deal 100% (+30% bonus Ability Power) additional magic damage. Basic attacks against non-structures lower Crystal Slash's cooldown by 0.25 seconds (quadrupled against champions).
Skarner is shielded for 10/11/12/13/14% of maximum Health (+80% bonus Ability Power) damage for 6 seconds. While the shield persists, Skarner gains movement speed that ramps up to 16/20/24/28/32% over 3 seconds.
Passive: Crystallizing enemies with Fracture and Impale grants Crystal Charge for the disable duration and reduces the cooldown of Fracture by the same amount.Active: Skarner summons a blast of crystalline energy, dealing 40/65/90/115/140 (+20% bonus Ability Power) magic damage, slowing targets hit by 30/35/40/45/50% for 2.5.Enemies hit by Fracture are afflicted with Crystal Venom for 5 seconds, causing Skarner's next basic attack against them to deal 30/50/70/90/110 additional physical damage and stun the target for 1.25 second.
Skarner suppresses an enemy champion for 1.75 seconds, dealing 60% Attack Damage physical damage plus 20/60/100 (+50% bonus Ability Power) magic damage. Skarner can move freely during this time, and will drag his helpless victim around with him. When the effect ends, Skarner's target will be dealt the same damage again.
