In this event: What's the difference between the Skin Shard and Skin Orb?
Both say project, but cost different.
Both say project, but cost different.
Shard is a skin shard for a previous PROJECT skin (No Jhin/Vayne/Vi).
Orb is basically a hextech chest but it guarantees a skin shard. PROJECT skins are technically possible but you're rolling among the entire catalog.
The Skin Orb has a skin shard and orange essence (not necessarily a Project skin). Whereas the Skin Shard is a Project skin.
