They should add a legendary upgrade to this item:

Emerald sighstone:

Item cost: 2000

Ruby sighstone +700 gold

Stats: +300 health

Now max 6 stacks, earn a stack each 4 minutes, still full refill when back.

New passive: If wearer hasn't taken damage in last 5 seconds, +10% movement speed and the wards placed with this item reveal nearby invisible units for 5 seconds
