Runes are single-use items that you can use to add effects to your squad. Runes come in several different types as well as different rarities. Runes function for a limited time and can only be used once.
Please Note: Runes are not permanent and will disappear from your inventory if not used within 6 days of when you acquire them. You can see how much time a Rune has left by tapping on it for the information screen, as described above.
You can have up to 2 Runes active at one time.
To use a Rune, tap on the Heroes button on the home screen. Once you’re on the squad screen, tap on the Runes button on the right-hand side of the screen. To see information about a rune, tap on it in the inventory and an information window will open.
To activate a Rune, drag and drop it from the inventory on the left side onto one of the Rune targets in the center of the screen.
When you have a rune(s) on the target, you will have the option to Cancel, and return to the empty Rune screen, or activate to add the effect of the Rune to your squad and start the timer on the Rune. Once the timer runs out, the Rune’s effect will be removed from your squad.
