Starting from the League of Legends Patch 14.1 Update, the items received a massive overhaul which removed the Mythic tier and changed the existing pool. Here's an all-around guide for the League of Legends 2024 Assassin Item Build.

League of Legends Patch 14.1 also adjusts Lethality to be 1 Armor Penetration per point of Lethality rather than scaling per level.
