Teamfight Tactics Set 4: Fates launches globally on September 16 alongside patch 10.19, introducing transformative gameplay systems that redefine strategic decision-making. This comprehensive guide covers the revolutionary mechanics, Ionia-inspired cosmetics, and advanced tactics you need to dominate the new meta from day one.

New Game Mechanics Added in TFT: Fates
TFT: Fates introduces four groundbreaking mechanics that fundamentally alter how players approach team composition and economy management throughout each match.
Chosen System
The Chosen mechanic presents special two-star units in your shop that retain their full gold value when sold. A Chosen tier-one champion costs three gold, maintaining this pricing structure across all tiers. Beyond the immediate two-star advantage, Chosen units receive 200 bonus HP plus one additional enhancement: 500 extra health, 35% spell power amplification, 50 attack damage, or 25% mana cost reduction.
Strategic limitation: You may field only one Chosen unit simultaneously, making selection timing crucial. Selling your current Chosen resets the availability of these special units in subsequent shop refreshes.
Cultist Trait
Cultist champions break convention by not receiving direct trait bonuses. Instead, they collectively empower Demon Lord Galio, whose strength escalates with active Cultist count. At the maximum nine Cultist threshold, Supreme Overlord Galio manifests with over 7,000 HP and 600 AD, serving as an immense frontline presence with game-changing area-of-effect crowd control.

Moonlight Strategy
Moonlight comprises exclusively one-cost and two-cost units, enabling rapid trait completion during early rounds. These champions automatically upgrade their lowest-star-level ally at battle commencement, facilitating unprecedented early three-star acquisitions and potentially introducing four-star champion possibilities for the first time in TFT history.
Warlord Progression
Warlord units accumulate power continuously throughout matches regardless of trait activation status. Each combat victory grants stacking bonuses to health and spell power, capping at five accumulations. With nine active Warlords, each champion receives 600 HP and 50 spell power, potentially reaching 400 bonus HP and 50 additional spell power through victory stacking.
While most classes and origins debut fresh, several veteran traits return including Assassins, Brawlers, Vanguard, Mages, and Mystics. New combat styles feature Adepts (enemy attack speed reduction), Duelists (escalating attack speed), and Hunters (lowest-health targeting). For comprehensive trait details, consult the official Complete Guide covering all synergies and optimal combinations.
TFT: Fates Goes to Ionia
Extending the Spirit Blossom visual theme, TFT: Fates transports players to the mystical region of Ionia. Three premium arena skins feature dynamic reactions to match outcomes—victorious rounds trigger celebratory animations from the environmental creatures. Additional Ionia-inspired cosmetic options become accessible through the Fate Pass+ system.

The Fate Pass+ retails for 1,295 RP, delivering new explosion effects, Ionia-themed Little Legends, and the innovative Star Shard progression mechanism. This system permits upgrades to any owned Little Legend (minimum tier-one requirement). The pass provides 300 Star Shards, while direct purchase bundles offer 625 RP alternatives for immediate acquisition.
Early Game Optimization
Prioritize Moonlight compositions during initial stages to capitalize on early three-star potential. Monitor Chosen appearances carefully—delaying your selection until stage 3-2 can provide access to higher-tier options while preserving economic flexibility.
Mid-Game Transitions
Cultist strategies require careful unit preservation to reach critical mass for Galio summoning. Avoid the common mistake of selling Cultist units prematurely; their collective power scales exponentially at higher trait levels.
Late Game Power Spikes
Warlord compositions demonstrate remarkable scaling potential but demand consistent victory maintenance. Position your frontline to protect key Warlord carries, as defeated rounds interrupt their stat accumulation. For weapon and item optimization strategies, reference our comprehensive Weapons Unlock guide covering optimal itemization paths.
