Alternate Passive for Varus

Varus' passive is perfect as the way it is. It rewards players who farm correctly and make good trades, allowing you to become an absolute beast stacking your w like crazy. However, the passive I am proposing is pertaining to Varus' lore.

Broken Past/Shards of a Forgotten Past 2/3 types of Shards that empower one soul in the body are strewn across the map like Bard's chimes, allowing you to gather them if you are near them. These also spawn by defeating enemy champs. Shards boost a different stat, up to a cap. When a certain amount of a type of shard is met, they turn into a different form based on what shards were collected. Salvation Shards boost Attack Speed/AD while Darkin Shards boost AP/Attack Speed. For example, if you received enough Cure shards, Varus will retreat and you now play as Valmar with Kai's ghost. Kai: A: will take a portion of Valmar’s taken damage as true damage. If slain, Kai will not be able to assist Valmar for a short period of time, which can be reduced every time you damage an enemy champ. B: Revives Valmar if defeated (guardian angel) C: Heartlight: has melee auto attacks with pretty high range, allowing him to mark targets for Valmar to hit. Hitting marked targets grants Valmar bonus attack speed for x seconds, increasing exponentially and refreshing if the target is slain while doing so. Repeatedly hitting a marked target with autos or abilities refreshes the duration up to a cap.

If you got enough Darkin Shards however, you can play an empowered Varuss.
