In order to protect your gold from attackers, a so-called savefight, protection fight or simply sf is made. After this fight with another player, you are protected for exactly 60 minutes. You cannot be attacked during this time. If an opponent tries to attack during this time, he'll get the following message:
Your desired opponent [Name] has already had a fight within the last hour! Each player can only be attacked once within an hour!
The most sensible approach to the mission
With Premium: Backup fight - 4x10 minutes mission - Backup fight - 4x10 minutes mission - Backup fight - 4x10 minutes mission - Backup fight
'Without Premium: Backup Battle - 3x10 minutes Mission - Backup Battle - 3x10 minutes Mission - Backup Battle
The advantage: With Premium you can't avoid 2 fights for security anyway. Without Premium you need at least one fuse fight to be protected during the mission. If you proceed as described, the time is exactly divided. If you have accounts with and without Premium, the procedures "With Premium" and "Without Premium" fit perfectly into each other, so that you can play wonderfully parallel.
