I just found a way to make Relic Shield NOT require an ally to be nearby to proc the passive.

Found this while playing
support (don't hate me) and as far as I know only works with him.
So it basically lets you proc the passive, give you the healing, and it counts towards the quest of earning money with the item (but does not give double gold for the minion kill), making it easy to complete the quest in a solo lane. Also works with all its upgrades.
So anyway, would I get banned for using it? :D
