What is the Golden Revel Token and why do I want it?

Check out its rewards, it has very high quality rewards for using one :)

If you own one of the select Lunar Revel skins (ex: Dragonblade Riven, Warring Kingdoms Vi, etc.) you can use a golden token in your loot tab to craft a "free" golden chroma for one of those skins.

I was wondering this. Looks like I'll just get 2 of those revel orbs. At least they have a chance to get other drops.
