At the beginning of the game tutorial, you can choose from one of two basic avatars — Garvel or Julia. After that, if you want to switch to a new Hero, you'll need an "Unlock and change" item. Once you've unlocked a Hero, you will no longer need to use the "Unlock and change" item to switch to them. Instead, you'll have to use the "Change avatar" item.
 

Unlocking a Hero avatar

 
If you haven't yet unlocked the desired Hero avatar, follow the instructions below.
 

Click on the icon showing your Hero's avatar to open the Hero and Captain selection menu.

 
 
Open the "Change avatar" menu to the right of your Hero's stats.
 
 
Click on a grayed-out avatar that you wish to unlock.
 
 
Click on Unlock in the "Choose an avatar" section.
 
 
Next, you will be prompted to either use an available "Unlock and change" item or purchase one for 1M gold and use it straight away.
 
 
Once you've used the item, the desired avatar will be unlocked and will immediately replace your current Hero.
 
 

Switching between unlocked Hero avatars

If you wish to switch between Hero avatars that you've previously unlocked, follow the instructions below.

 

Click on the icon showing your Hero's avatar to open the Hero and Captain selection menu.

 
 
Open the "Change avatar" menu to the right of your Hero's stats.
 
 
Click on the icon showing the unlocked avatar.
 
 
You will notice that the button now reads "Choose" instead of "Unlock."
 
 

Next, you will be prompted to use an available "Change avatar" item. You can purchase this item in packages.

Once you've used the item, the desired avatar will immediately replace your current Hero.

Tip.
 
You can only change your Hero's avatar once every 20 hours.
