TFT Patch 16.3 Drops Leveling Tweaks, Unlock Revisions, and Major Reworks

Teamfight Tactics patch 16.3 introduces broad system tweaks (XP leveling changes from Level 8–9 and adjusted unlock odds for 4/5-cost units), aura behavior adjustments, and a major slate of unit/trait reworks and nerfs/buffs (including Diana/Leona reunification, Kindred rework, Kai’Sa level change, and various Piltover/Ixtal/Darkin/Bilgewater updates). It also revises unlock rules to make 4/5-costs harder to three-star (while contested play eases two-star goals), introduces new augments (like Cosmic Calling), buffs core items (Nashor’s Tooth, Edge of Night), and buffs/nerfs across artifacts and Radiants, alongside numerous balance fixes to smooth tempo and gameplay health.
