Teamfight Tactics concludes 2019 with the impactful 9.24 update, introducing groundbreaking mechanics that reshape competitive strategies. This final patch delivers the long-awaited Soulbound class featuring Senna and Lucian, alongside Amumu as a powerful tier 5 addition. Beyond new champions, players will discover refined interface elements and carefully calibrated balance adjustments designed to refresh the meta.
Riot Games revealed the Soulbound concept weeks prior, and now these innovative units are live for experimentation. The signature trait activates when fielding both Lucian and Senna, transforming the first fallen champion into an invulnerable spectral form that continues combat until both partners are eliminated. This unique mechanic demands strategic repositioning and timing considerations that separate novice from expert players.
Soulbound Units Senna and Lucian Join the TFT Board with Amumu
The Soulbound synergy represents one of TFT’s most innovative mechanics to date. When both champions are on the battlefield, the first to fall becomes an untargetable spirit that persists in combat, dealing damage but unable to be attacked. This creates fascinating tactical decisions around which champion to sacrifice first based on itemization and board state.
Expert players should position Lucian and Senna on opposite sides of their formation to prevent simultaneous elimination. The spirit mechanic effectively provides temporary numerical advantage, allowing your remaining units to survive longer while the spectral partner contributes damage. Understanding when to intentionally sacrifice one champion versus protecting both requires deep game knowledge and situational awareness.
Senna operates as a tier 2 Shadow unit with exceptional support capabilities. Her Piercing Darkness ability channels a beam toward your farthest ally, damaging enemies along its path while granting allies bonus on-hit damage for 5 seconds. Despite dealing damage, she functions primarily as an enabler for carries like Lucian. Positioning Senna adjacent to your primary damage dealers maximizes her value, while placing her too far forward risks premature elimination.
Lucian complements Senna perfectly as a Light origin champion costing 4 gold. The Culling unleashes four enhanced basic attacks that scale with attack damage and apply on-hit effects. This synergy makes Lucian exceptionally powerful when paired with items like Guinsoo’s Rageblade or Statikk Shiv, amplifying his damage output significantly.
Amumu stands as the sole tier 5 addition, bringing crucial durability to Inferno compositions as a Warden. Curse of the Sad Mummy triggers an area-of-effect explosion that damages and stuns surrounding enemies. His high cost makes him a late-game priority for players running Inferno builds seeking frontline stability.
TFT Patch 9.24 Brings Several Minor Changes to Units and Traits
Balance modifications extend across multiple traits, with Shadows receiving the most significant adjustment. The activation thresholds increased from 2/4 to 3/6 units, requiring more commitment to achieve maximum damage bonuses. This change prevents overly efficient Shadow compositions while maintaining the trait’s viability for dedicated builds.
Champion-specific tweaks include substantial improvements to Lux’s early-game performance. Her ability damage at one and two-star levels received meaningful buffs, though this comes at the cost of reduced maximum mana. These adjustments make Lux a more attractive early purchase while encouraging strategic mana management.
Additional updates encompass interface quality-of-life improvements, select item rebalancing, and comprehensive bug fixes addressing various gameplay issues reported by the community.
Mastering the new Soulbound composition requires understanding several advanced concepts. Begin by prioritizing Senna in early rounds, as her tier 2 cost makes her accessible for establishing early synergy. Transition carefully into Lucian once you’ve stabilized your economy, avoiding premature rolls that jeopardize your gold reserves.
Common mistakes include positioning both Soulbound champions too close together, risking simultaneous elimination that negates their unique trait. Another frequent error involves over-investing in the composition without proper backup plans, leaving you vulnerable to counter-compositions.
For optimal performance, consider pairing Soulbound with complementary traits like Light or Shadow. This approach creates more flexible compositions that can adapt to various opponent strategies. Remember that while powerful, Soulbound shouldn’t be forced every game—assess your opening items and champion offerings before commitment.
Amumu serves as an excellent addition to any late-game composition, not just Inferno builds. His crowd control and tankiness provide value across multiple team compositions, making him a versatile late-game pickup regardless of your primary strategy.
