|"You belong in a museum!"
-  was briefly introduced on the PBE server in the Preseason 2015 patch. Due to a mistake, it did not build into Essence Reaver.
- The base stats are efficient without the passive.
The mana restoration passive triggers as an On-hit effect. Abilities that apply on-hit, such as Ezreal's Mystic Shot and Gangplank's Parrrley will trigger the passive. It will therefore also not apply when attacking a turret.
This item comes in useful for champions who are AD based, cast spells constantly but also perform autoattacks often, abusing both the mana restore and lifesteal, for example Jayce, Gangplank, (top lane) Udyr, Ezreal, Sivir or Poppy.
