Raid shields temporarily protect your base from being raided by other players for a set amount of time, which prevents other players from taking your accumulated Raid Chips and Medals. Once a raid shield has been applied to your base, you are prevented from raiding any other players until the raid shield has expired or you decide to raid another player.
Raiding another player will remove the raid shield’s effect early. If you attempt a raid while your shield is activated, you will receive a pop-up warning, which can be disabled.
You can find these in the store under the MISC tab. There are three kinds of shields that will protect your base from being attacked for different lengths of time:
- 4 hour - Costs 15 Energon
- 12 hour - Costs 40 Energon
- 24 hour - Costs 75 Energon
