A renowned leaker named Julex Gameplays gave some new information about the Mythic Shop in the upcoming League of Legends patch 12.23 on November 19, 2022. This is supposedly the end of the season patch and is anticipated to come out somewhere in mid-December. 

On the basis of this leak, the new skins that may arrive in the new Mythic Shop rotation consist of prestige versions for Project Sylas and Arcade Caitlyn, alongside other rare skins such as Hextech Rammus and Hextech Kassadin. The time frame of these skins and their prices have been mentioned in detail in this article. 

Another addition will be made namely Ashen Knight Mordekaiser to the game with League of Legends patch 12.23, and this will be the final addition to this skin line as of now. The Ashen Slayer skyline will be discontinued as a Mythic and will be launched as regular skins from next year onwards. 

As mentioned earlier, League of Legends will have prestige Project Sylas, prestige Arcade Caitlyn, Hextech Rammus, and Hextech Kassadin featured in the Mythic Shop for patch 12.23. This also means that Hextech Poppy, Soulstealer Vayne, Star Guardian Neeko prestige version, and MSI 2021 Conqueror Jax prestige version will be leaving the Shop. 

The prices for these upcoming entries to the Mythic Shop for patch 12.23 are mentioned below: 

3 Month Duration 

• Hextech Rammus (100 Mythic Essence) 

• Hextech Kassadin (100 Mythic Essence) 

• Ashen Knight Mordekaiser (100 Mythic Essence) 

1 Month Duration 

• Prestige Arcade Caitlyn (150 Mythic Essence) 

• Prestige Project Sylas (125 Mythic Essence) 

As per this list, it can be said that quite a few unique skins are added to League of Legends’ Mythic Shop with this season’s final patch. Among them, Hextech Rammus and Hextech Kassadin are rare as the skin line itself has been discontinued. 

Fans who are curious should think of spending their Mythic Essence on them as the Hextech skins may not return soon. Also, the Ashen Knight Mordekaiser will also be the final Mythic skin under the skin line's banner. 

Previously, the Ashen Knight skin line had three other skins and this marks the fourth addition to the set. League of Legends players who have the previous three should get this one too as there is no definite timeline on when they will return to the Shop again. Also, the developers are planning to prioritize a brand new Mythic skin line in 2023. 

The three skins mentioned above will remain in the Shop for three months, giving fans plenty of time to obtain them. 

The prestige skins for Arcade Caitlyn and Project Sylas will remain in the Mythic Shop for a month. While Caitlyn’s skin might not be that popular, Project Sylas is one of the most attractive cosmetic items for the champion. 

Fans who love to play Sylas should get this prestige skin if it arrives in-game. Moreover, Sylas is one of the strongest champions in the game presently, making the 125 Mythic Essence cost well worth it if fans are planning to play Sylas frequently. 

It should be kept in mind that all of this information is based on leaks and Riot Games may bring changes to the official release.
