How do you get the Dark Cosmic Diana Chroma Icon?
It came from an event shop. Riot's description in the client reads: “An icon that comes with the Event Shop-exclusive chroma.”
Is the Dark Cosmic Diana Chroma Icon still available?
No. The Dark Cosmic Diana Chroma Icon came with an Event Shop-exclusive chroma: you got it by buying that chroma with event tokens in the 2024 event shop. Past event shops do not return, so it cannot be earned anymore.
