Game breaking hero exploits and item interactions fixed with 7.40c Dota 2 patch

Along with balance changes, Dota 2's most recent patch has also fixed a long list of bugs, including Medusa’s infinite health exploit, Anti-Mage Magebane's Mirror Facet exploit, and Morphling replicating Monkey King with Aghanim's Sceptre.

Item bugs fixed

• Helm of the Overlord: Now correctly grants bounty and experience for dominated creeps, and experience is properly awarded to Lone Druid instead of his Spirit Bear.
• Smoke of Deceit: Can no longer be used directly from the stash.
• Blood Grenade: Bonus health now updates correctly when stack count changes.
• Quick Buy: Fixed an issue where component items would not always be removed from the queue after a recipe purchase.
• Illusion Rune: Now properly disjoints projectiles upon activation.

Major exploits removed

The patch eliminates several severe bugs that created unfair advantages or unintended instant-kill scenarios. Most notably, a one-shot interaction between Anti-Mage and Spectre was fixed. Previously, an Anti-Mage with Aghanim's Shard and the Magebane's Mirror Facet could instantly kill a Spectre when using Counterspell while walking on a Spectral Dagger path targeted at another unit.

Another major fix targets an infinite health exploit involving Medusa, Lifestealer, and Shadow Demon. Before the patch, Medusa was able to get infinite health when purchasing Heart of Tarrasque while Lifestealer had infested her and then using Shadow Demon's Disseminate with the Promulgate Facet targeting Medusa.

Patch 7.40c has also got rid of a bug where Morphling, when replicating Monkey King with an Aghanim's Scepter, would spawn soldiers from Wukong's Command.

Other hero bugs fixed

• Arc Warden's Tempest Double can no longer pick talents, as originally designed.
• Bounty Hunter can now correctly target Lone Druid's Spirit Bear with Friendly Shadow.
• Brewmaster's level 25 talent now correctly applies its effect to his summoned Brewlings.
• Clinkz's Infernal Shred was ignoring more armour than intended, a bug now resolved alongside his significant balance nerfs.
• Doom can now properly acquire the Petrify ability from the Ancient Prowler Shaman neutral creep.
• Largo's Encore ability will now consistently refresh an existing buff on the caster or the target.
• Morphling will now correctly lose the bonus damage from unused stone remnants when ending a replication of Earth Spirit.

7.40c game play update focuses on reshaping the meta and fine-tuning heroes as the pro scene prepares for a packed tournament schedule. Most importantly, Largo was added to Captain’s Mode, and mere hours after the patch hit the server, the hero was already picked in competitive play and was played successfully in the offlane by 1w Team during FISSURE Universe: Episode 8 group stage.
