TFT 16.4: New Augments, Leveling Tweaks, and Broad Balance Pass
Teamfight Tactics patch 16.4 adds new Augments (including Gilded Steel and Trials of Twilight II) and a World Runes revamp, tunes leveling XP, and adjusts Level 7 odds to widen viable routes to top four. It reshuffles unlocks (Kennen moved to 7 stars, Tahm Kench earlier), buffs and nerfs a broad swath of units and traits (notables include Aatrox, Aurelion Sol, Sylas, Ambessa, Lissandra, Bard, Tristana, Xin Zhao, Darius, Jinx) and revises core items/artifacts (Nashor's Tooth, Warmog's, Gargoyle's, Radiants). Economy Augment nerfs aim to curb three-star 4-costs, while Festival of Beasts revivals bring buffs to Shyvana, Olaf, Vladimir, and more. Bug fixes, balance adjustments across Piltover/Ionia/Gunslinger, and a return to regular Wednesday patch cadence are also included, plus ongoing tweaks to Gold/Reroll economy through updated Augments.
