Dota 2 7.39d Patch Notes: Balance Changes Before The International 2025

August 5, 2025

Just ahead of The International 2025, Valve has released patch 7.39d for Dota 2, which includes some important balance changes, some item adjustments, and a new mechanic called Quartero’s Curios. The patch is designed to help transition the game into the largest and most-known tournament in the Dota 2 esports scene, while adjusting the meta without even greatly altering the game itself.
