How do I evolve my heroes?

To evolve your heroes you need to get hero medals. There are different ways to get medals:

• Open free or premium chests, if you already have the hero, those will reward the equivalent amount of medals for that hero.
  
  
• Raid the daily dungeons, each dungeon will reward a medal from its element. Starting at dungeon level 16, you will get an extra medal for a common hero.
  
  
• You can buy medals from the Guild, Blitz or Arena shop.
  
  
• Magic Medals are earned through "El Dorado" expeditions and are a great source of hero medals.

Medals Needed to Evolve/Unlock Heroes

Unlock: ⭐️ - 10 medals
⭐️ -> ⭐️⭐️ - 20 medals
⭐️⭐️ -> ⭐️⭐️⭐️ 50 medals
⭐️⭐️⭐️ -> ⭐️⭐️⭐️⭐️ 200 medals

10 medals are used to unlock the hero.

Each time a hero evolves the medal counter starts at 0.

30 medals = 2 stars hero with 0/50 medals.

80 medals = 3 stars hero with 0/200 medals.
