Riot Games confirmed the auto-battler will migrate from the Hextech engine to Unreal Engine with the launch of Set 18 on August 13. A dedicated client, separate from LoL, follows on October 10, four patches after the set release. The change addresses constraints that have limited TFT since its June 2019 debut as a LoL game mode. Tied to the same client and engine, the game faced restrictions on technical features and patch timing. Riot framed the migration as a foundation for long-term viability, with game content unchanged. The Set 18 update will be larger than usual due to the engine swap, but subsequent patches are expected to return to normal size. A four-week PBE period begins July 15 to handle an anticipated increase in bugs from the migration.\u003c/p\u003e","blueskyPost":"Teamfight Tactics is leaving the League of Legends client behind.
