Soft Skarner rework idea from a serious fan.
Energizing Venom: Skarner’s abilities apply Mineralizing Venom to enemy champions and large monsters. Mineralizing Venom deals x damage over 2.5 seconds to affected and nearby allied units. Affected champions near other champions with Mineralizing Venom receive a 35 percent slow.
Crystal Slash: Skarner deals physical damage to all enemies within range. If Skarner is near a target with Energizing Venom Crystal Slash deals bonus magic damage. Basic attacks reduce Crystal Slash's cooldown by 0.25 seconds, quadrupled to 1 against enemy champions.
Crystalline Outgrowth: After a brief delay Skarner summons a patch of crystals at target location. Champions struck by the emerging crystals are grounded for 1.5 seconds. Enemy champions standing on the crystals are slowed by x percent, increasing to x percent if they are on the center of the patch. Crystal Outgrowth grants Skarner movespeed in a wide area around it, which increases the closer Skarner is to the center. If Skarner contacts the patch he gains a shield for x health.
Fracture: After a brief delay Skarner unleashes a blast of energy in a cone in front of him damaging and marking enemy units. Skarner gains movement speed for each champion hit, which decays over 1.5 seconds. Skarner’s basic attacks consume the mark to stun the target for 1 second. Consuming a mark grants Skarner a burst of move speed that decays over 1.5 seconds.
Impale: Skarner rears his stinger, rooting his target for 0.25 seconds as he brings it down, dealing 60% AD physical damage, suppressing them for 1.75 seconds. At the end of the duration, the target takes the same damage again. Impale increases the damage of Mineralizing Venom on all targets by 50 percent for 5 seconds.
