[Champion Concept] Karlov, the Spectral Shield

[ROLE: WARDEN]

[LORE] Karlov was a Demacian soldier who carried a shield passed down to him by his ancestors. Through his military career, Karlov became renowned for his prowess using his shield. However, one day during a battle against Noxus in a Demacian town, Karlov noticed a Noxian warrior about to murder a group of citizens. Karlov charged in front of the citizens to protect them, but the Noxian broke Karlov's shield and slayed him without remorse. The Noxian slaughtered all of the citizens but one, until Karlov's spirit appeared, manifested in a spectral form with his shield reforged and now a part of himself. As the Noxian swung his axe ready to behead the last citizen, Karlov warped to the innocent and deflected the blow. After a short battle, the Noxian was dead, and Karlov vowed to use his new supernatural powers to protect the weak and slay the unrighteous.

[PASSIVE] "Metaphysical Form" When Karlov has not taken magic damage recently, he gains passive reduced physical damage taken. This bonus is removed shortly if Karlov takes magic damage. Karlov is also immune to unit collision.

[Q] "Aether Strike" Marks a location and selects a direction. Karlov blinks to the target location. Deals magic damage to and knocks back enemies in the selected direction.

[W] "Spectral Counter" Channels shortly, while being able to move while channeling. A percentage (that scales with AP) of the non-turret damage that Karlov would take is instead stored as stacks of Retribution. After the channel is let go, Karlov consumes all stacks of Retribution sends a skillshot that deals magic damage equal to the consumed stacks and slows in a linear area of effect.

[E] "Protect the Weak" Blinks to target ally that has recently taken champion damage. Grants a shield and speed boost to them, while knocking back nearby enemies. Enemies that have done damage to the target ally recently are also briefly stunned.

[ULTIMATE] "Otherworldly Vengeance" Passively, Otherworldly Vengeance cannot be casted unless an allied champion is dead. When activated, Karlov grants himself and nearby allies increased movement speed, attack damage, ability power, and health regeneration for a duration of time. If an enemy champion is killed, the duration of Otherworldly Vengeance is refreshed. If no enemy champions were killed during Otherworldly Vengeance's original duration, Karlov is slowed and takes a percent of his current health as true damage.
