You level up your heroes by awakening them for 500 arcane crystals.
You can get arcane crystals in the guild by shattering the crystal. (Level 50)

New heroes start with level 1 of awakening. A Hero will level up once they have collected enough Awakening exponents. The first level advancement requires 250 Awakening exp. The cost of level advancement increases by 25 Awakening exp for each additional level.

The awakened hero is chosen at random, with heroes with a lower awakening level having a higher chance of being chosen.

You can see the information about your current hero awakening in the Hall of Heroes under the tab "Awakening".
