To use a super potion in Clash of Clans, follow these simple steps. First, ensure you are at Town Hall 11. You need to reach this level to access the super barracks.
Next, find the super barracks located on the northwest side of your base. Enter the barracks to see the available super troops, which depend on your regular troop levels.
Tap on the troop you want to enhance. If you have a super potion, you can use it to unlock the super version of that troop.
From your inventory or the super barracks, select the super potion and apply it to the chosen troop. This will transform the troop into its super version for three days.
Only certain troops can be upgraded to their super versions. Make sure to meet the minimum level requirements for these troops in your regular laboratory.
