This week we have quite a surprise with a triple hero update. The kind of update we haven't had for a very long while! This patch brings us Nyx Assassin, Keeper of the Light, and Visage. 

It also adds a feature against players that constantly decline or abandon matchmaking games by putting a cooldown on being able to find a match.

Also a back-end change has happened that was not mentioned in the patch notes is yet another change of the item icons, which can be found here.

This patch will hit the main Dota 2 client tomorrow or shortly after as usual. 

Of course, you can always read the popular datamining by Cyborgmatt on his very own blog, which will be updated very soon with the new patch news.

Workshop
