In the Dota League, there are many star ratings of heroes, and the higher the star rating, the stronger their combat power will be. It is not easy to get high-star heroes in the game. Upgrading a hero is one of the ways to get high-star heroes. Now let’s talk about how to advance the Dota League heroes. How to advance heroes in Dota League: In Dota League, players need to advance heroes with 2 props: 1. For star-level soul fragments (for example, 1 star soul fragments are required for 1 star to upgrade to 2 stars); 2. Upgrade equipment with corresponding attributes; Hero advancement has certain requirements for the number of these two props. The higher the star rating, the more props materials are needed for the advancement of heroes. When you slow down the corresponding number, heroes with 3 stars or above can be advanced.
