Each hero unlocks Awakening when they reach level 30. They can be awakened up to 10 times by exchanging a combination of elixir, items, and Awakening Gems. With each awakening, a hero's awakening skill is improved, and they gain bonus attributes.
An awakening skill is a passive skill that triggers an effect on the third hit of each basic attack combo. Knockup (1s), Silence (1s), Snare (1s), and Stun (1s) have a percent chance to trigger, whereas Reduce Armor (3s) and Reduce Resist (3s) always trigger for a percent value.
