Ruby Sightstone Idea change.
Costs 1000 more to forge and the entire team may only have one. Increases the ward count for the user to 5 wards on the map at max. and allows 25% increased ward drop range.
This way a support can go this route if he feels that his team isn't warding hard enough. But if the team is warding well then the support can keep the extra gold and invest in their respective income/support warding item.
