[Champion Concept] Shockblade, the Master of Lightning

Shockblade is a melee/ranged type assassin who excels on the battlefield. His speed, damage and range allow him to shred minion waves and play well in teamfights.

Passive: (Shockwave) After every 3 skills Shockblade uses, the next basic attack you strike will give back 30% of your current mana.

Q: (Lightning Slash) Shockblade throws his lightning sword in a narrow but long range, dealing 50/70/90/110 (+30% AP) magic damage to target struck, slowing them by 25% for 3 seconds. [Mana cost: 55, Cooldown: 5 seconds]

W: (Lightning Burst) Shockblade emits a large burst of lightning, dealing 70/80/90/100 (+30% AP) magic damage to those in its range, also giving Shockblade a shield that protects him from 100 damage.

E: (Lightning Rain) After a short delay, Shockblade summons a large blast of lightning to appear from the skies, dealing 80/90/100/110 (+10% AP) magic damage to those in its large range.

R: (Final Strike) Shockblade teleports to a nearby enemy, knocking them up into the air, dealing 150/180/210 (+30% AP) magic damage and giving yourself 20% bonus armor penetration for 15 seconds after use.
