Valve has released patch 7.38c for Dota 2, which not only introduces balance adjustments but also fixes several serious bugs affecting gameplay. Additionally, the developers have added an important change that was accidentally omitted in the patch 7.38 notes: Roshan no longer drops Aghanim's Blessing.

In the new update, Valve has addressed several critical issues impacting game mechanics:

General Fixes:
The Tormentor no longer spawns on top of a hero when testing the map.
Fixed an issue where a team could learn that the opponent activated Smoke of Deceit without having vision.
Removed an exploit with Boots of Travel that allowed generating an infinite number of teleportation scrolls.
Fixed a bug where a hero could lock their model or position through Roshan's grab animation.
The duration of the Haste rune now properly updates according to the rune cycle.

Specific Hero Fixes:
Alchemist – The indicator for received Scepter no longer shows an incorrect amount.
Bristleback – Bonus damage from Aghanim's Scepter is no longer considered reflected damage.
Doom – Correct calculation of buyback cost through Devil's Bargain.
Kunkka – Level 25 talent now correctly works on Tidebringer.
Magnus – Skewer without Aghanim’s Shard no longer destroys trees.
Medusa – Venomous Volley no longer works on illusions when Split Shot is active.
Naga Siren – Deluge no longer sets the same movement speed for all enemies.
Windranger – Focus Fire is no longer canceled by a brief loss of target vision.
Zeus – Updated Heavenly Jump description to correctly display the vision area after the jump.

Ability Draft Changes:
Pangolier no longer receives Roll Up when selecting Shard without Rolling Thunder.
Kez no longer receives Shodo Sai without the appropriate abilities.

These changes aim to improve the overall gaming experience and eliminate unfair advantages caused by bugs. The update is now available for all players. Valve continues to actively support Dota 2, addressing issues and enhancing game balance.
