Notes
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.
Strategy
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.
