Mythic Aura

Mythic Aura grants a bonus in stats & Mana generation for “first use heroes” and applies negative stat / Mana Generation due to “fatigue” when heroes are used 4+ times.

Click for Additional Information & Table of Effects Imposed by Mythic Aura

• The FIRST time a hero is used, they get a positive Mythic Aura which grants them +20% boost to Attack & Mana Generation.
• The Second & Third time a hero is used, there is no Mythic Aura. They’re just your normal every day hereos (plus whatever bonus you get from the difficulty you chose)
• From the Fourth Fight onwards using a specific hero however, the specific hero starts getting fatigued… They start getting negative effects.
