Ruby Sightstone Change Idea
Instead of having an upgrade path that adds more stats to itself. It'll have a very unique effect.
> Sightstone becomes ethereal. Another item may be place in this slot but any active or passive effects will be disabled. One upgraded Sightstone cannot be sold or moved to another slot.
What this means is that you can now buy say a Deathcap and have it in the same slot as Sightstone. But you will not gain the %AP boost. Just the 120AP.
This allows players to turn this into an item they can use. But the gold efficiency of that item will very iffy without passive/actives. Since the slots active will remain as wards.
