Retopology

TwinDenis

Hi, I am new to 3d and was wondering what tools are you using in order to make simple high poly to low poly transitions. 
In other words, how do you go from hd model to low poly one that is as simple as a dota 2 item.

You can use the retopology option from Maya. You can do so by importing the high poly mesh in Maya and drawing the new polygons over that. This tutorial should be useful, https://www.youtube.com/watch?v=xpDWta5O3n8.
