"Raid" is a feature to win any map that have been already won with 3 stars, without a battle.
Simultaneously with the appearance of "Raid", the prizes "125 energy", "75 energy" and "50 energy" were excluded from the game. These prizes were replaced with a "Raid ticket". One victory with "Raid" requires spending 1 "Raid ticket".
In addition, a similar "Raid" option in "Dungeon" began to lead to victory in 100% of cases. Previously, when using the "Raid" option in "Dungeon", there were possible defeats.
