You should feel confident using Prestige Points and event tokens on the skin you want most. Here's the complete lineup of 2020 prestige skins. No spoilers on unrevealed thematics!
*We're trying something different with Soraka: This'll be our first Prestige Edition of a previously-released skin, as a test to gauge interest in Prestiges for older content.
*During Worlds 2018, we released K/DA Kai'Sa Prestige Edition as a one-off before fully defining Prestige as a skin type. It was much harder to unlock than today's Event Prestige skins, and there wasn't yet clarity around what Prestige was or how Prestige and Event Passes worked. While this won't be a re-release of Kai'Sa's 2018 Prestige, we hope a second Prestige gives Kai'Sa mains who missed the 2018 Prestige skin a fresh shot at earning something exclusive for their champ.
All 2020 Event Prestige skins will return in the end of the year Prestige Shop for purchase with Prestige Points. Unlocking a 2020 Prestige skin via loot drop or skin shard reroll will only grant the border and icon if the skin is still obtainable via 2020 Prestige Points (for Prestige Point skins) or Event Tokens (for Event Prestige skins).
Border and icon cutoff dates:
2020 Prestige Points will expire January 28th 2021, 13:00 PT. At that point, 2020's Prestige Point skins will become unobtainable outside of Hextech Crafting drops.
