You can request energy in the guild chat. To do this, press the Request button in the bottom left-hand corner of the Chat tab. You will see the Energy button. After pressing this button, your request will be displayed in the guild chat. After you receive the maximum amount of energy, the request will disappear.
Receiving energy correctly requires a stable internet connection.
You can claim the energy your guildmates send you in the Gifts section.
You can request energy once every 8 hours.
