How do you get the Divine Phoenix Anivia Icon?
It was released during a limited-time event. Riot's description in the client reads: “This icon was acquired during the 2021 Coven event.”
Is the Divine Phoenix Anivia Icon still available?
No. Riot tied the Divine Phoenix Anivia Icon to 2021 (limited-time event), and it does not normally bring back past event rewards or bundles.
