An Ayatan Star is a small treasure that can be inserted into Ayatan Sculptures to greatly increase their Endo value when traded in. Once slotted, a Star cannot be removed. They come in two colors: the more common cyan, and the rarer amber. Stars can also be traded in by themselves for a small Endo payout. Sculptures have 3 to 4 slots to insert Stars in, and each slot only accepts a specific color. Inserting Stars will also cause the Sculpture to visually animate, with more Stars improving the Sculpture's range of movement.
At Mastery Rank 10, players gain the ability to auto-install Stars into their Sculptures.
Stars are dropped randomly from Storage Containers and lockers (including storage containers in Archwing missions). They have a noticeable glow and a unique marker on the mini-map (though Amber Stars have a slightly larger icon), and a specific sound plays when a Star is dropped. They must be picked up manually via a prompt, similarly to Syndicate Medallions. The Vacuum precept for Sentinels and the Scavenger Drone cannot pull Stars towards themselves, to prevent Stars from falling out of the map or otherwise becoming unobtainable. Kuakas in the Plains of Eidolon may also drop Stars.
