This is my first Custom Hero and had this idea in mind of the almighty old god (and one of my favorites * - *) and I said, Why not ?, in addition to Heroes of the Storm has very original ideas as to the gameplay of its characters (As Abathur and Cho'Gall) this idea even being possible in the game, if there is any skill, talent or statistic that makes it a Broken Hero, I'm sorry, but I'm not very familiar with the statistics, and sorry for my English is not my native tongue: 3
