You've Quested SightStone. Good. Now Keep Going.
A quest to get sightstone is fine.
What I'd like to see now is additional quests associated with upgrades.
- Place 20 wards from SS - 10s duration increase on all wards placed from SightStone
- Takedown 20 enemy wards (meaning expose and have it destroyed) - Unlock a Red Ward Slot
- Achieve 15 enemy sightings* and allow SS to carry an additional ward
- Takedown 10 rift scuttlers in a game and SightStone gains Blackout on a 600 second CD
- If Sweeper ward exposes 20 wards, or 5 champs (or 1 champ 5 separate times) then Sweeper duration is extended for 5 seconds and gives owner a 10% MS bonus whenever it's active
- If you have 10 Farsight Alterations in the Fog of War at the time time then FA will save up two stacks.
