How do you get the Star Guardian Mythic Essence Icon?
It came from Hextech crafting or loot. Riot's description in the client reads: “An icon crafted with the 125 Mythic Essence shop item for the 2022 Star Guardian event”
Is the Star Guardian Mythic Essence Icon still available?
Maybe. The Star Guardian Mythic Essence Icon was sold in the Mythic Shop for 125 Mythic Essence. Mythic Shop items rotate back in, so check the current rotation.
