How to level up heroes in Dota Underlords
When you buy a hero from the hero rotation, it is a 1* hero. You'll see a single copper-colored star just above their health bar. If you get three heroes of the same name and level, they will level up.
So: Three *Axes will automatically combine into one **Axe. Three **Axes will automatically combine into one ***Axe.
The more stars a unit has, the higher its health and damage will be, and the stronger its abilities will get. As a general rule, higher star units are almost always better than lower star units, regardless of their cost.
Since you can't control which heroes the game offers you, it's usually wise to buy a wide range of low cost units that you can potentially level up over the first few rounds.
