Valve has released Dota 2 update version 7.39c, which includes a wide range of changes: from adjustments to items and neutral artifacts to hero balance and map updates. These changes aim to adjust the current meta and reduce the strength of specific mechanics.

General Changes: Less True Strike, Map Adjustments

One of the notable changes is the weakening of True Strike—now Orb of Venom no longer guarantees a hit on evasions. Additionally, Blade Mail lost 1 armor point, and Hurricane Pike can be dispelled if used on an enemy. Harpoon has also been reworked—its "hook" can now be disjointed.

The map has been slightly altered regarding the placement of Watchers near Wisdom Shrines, and their activation radius has been reduced from 300 to 200. Furthermore, Roshan now perceives courier attacks as melee hero hits, and Tormentor no longer reflects damage from hero creeps.

Neutral and Jungle Changes

Neutral creeps have also been adjusted: most abilities now cast more slowly. Boglet, Croaker, Ancient Croaker—all now have increased cast points. Ancient Prowler Shaman can now apply Petrify without health restrictions if under player control.
