Battle Boosts give you an extra advantage during your attack. It might be an additional squad, extra squad space, additional starting mana, or other passive bonuses.
Challenge boosts will put your skills to the test, increasing the strength of your opponent's defenses.
You can select these boosts from the battle screen prior to beginning your attack (the diamond between "change troops" and "change ancient" buttons).


You can optionally purchase a Rare Boost Chest from the Battle Boost selection screen, or from the Chests section of the Build menu.
