Foil item
A Relic is a special version of a Unique item with its original balance values, a green item rarity colour and subtly animated decoration or "foil". Relics can only be found within a Reliquary area accessed with Ancient Reliquary Key in the Legacy league. Over time, GGG have adjusted some unique items to reduce or increase their power, with already-found items retaining their stats and becoming "Legacy", sometimes holding great value due to their better stats, and ultimately collecting in Standard league.
