Raids are guild events where an entire guild works together to take down a difficult boss.
Raids last three days. Raid are broken down into levels (
). After eight hours, if a level is not cleared, the boss' health will refill.
Once a level is cleared, the next level may be started immediately. Each time the boss' level increases, its max health increases by 1,000 points and it gains access to more powerful cards.
Guilds can bring their Siege Fortresses into battle with them against a raid boss, and Fortresses purchased during a raid are still available in that month's Guild War.
Raids are played with a separate energy bar, like Guild Wars and Brawls. It holds a maximum of 25 attacks (
), starts at 13, and refills one attack every 30 mins until the timer for the raid event his complete. Refills can be purchased for 
5 per attack. Unlike Guild Wars and Brawls, the battles in Raids are not played in Surge Mode.
After the timer for the raid event has completed, players can continue fighting any level they are currently on, but cannot start new levels. Energy regeneration stops (a bug previously allowed regeneration to continue during the Carnifex Raid, Oluth Raid, and Forsaken Horde Raid).
