You can exchange extra copies of troops for Souls by disenchanting them.
Troops can be disenchanted by performing the following steps:
- Enter the troop menu from the world map screen
- Select the troop to disenchant
- Select Upgrade
- Select the Disenchant tab (second from the right)
- Input the amount to disenchant
- Select the Disenchant button
The amount of souls a troop can be disenchanted for depends on the troop's base rarity:
|Base Rarity||Souls Earned
There is also the "Disenchant Max" button. This will disenchant all copies above 4 if the troop has been ascended to mythic rarity.
"Disenchant All Extra Troops" will disenchant all mythic troops in your collection down to 4 copies.
