When players have reached VIP Level 6, they will unlock the ability to Sweep the Hero Stages, which automatically completes the battle. Players can only use this ability on a stage, once they have already completed it with 3 Crowns. Sweeps can be carried out individually or up to 10 times with one tap.

Heroes which are ready to be promoted or upgraded can be seen with an exclamation mark on their profile. Tap the rank to begin promoting, or the shield with medals to begin upgrading. The hero will be promoted or upgraded when the countdown timer reaches zero. When a hero is promoted or upgraded, the player will gain a small amount of Might.

Battle and Hero Skills, Leadership Type and Command

Each hero has four Battle Skills. The first skill only activates if the hero is leading troops into battle. The other three are passive skills, which are further divided into two types.

1. Administration: skills that are activated the moment the hero is hired.and are permanently in effect.
2. Logistics: skills which will only be applied when the hero is deployed in battle.

When a hero is sent to battle, he or she can Command troops on the players behalf, effectively increasing the total number of troops that can be sent to battle. Heroes can only Command one specific troop type.

Each hero also has four Hero Skills. The first skill is the hero's Ultimate. These are extremely powerful and can only be activated when the hero has enough MP. The remaining skills are a mix of passive and active skills. Passive skills grant bonuses to the hero or its allies, while active skills can only be used by the hero in combat.

Tips

Trickster, Scarlet Bolt and Sage of Storms are often referred to as "The Golden Trio", because they are the heroes players should upgrade to Legendary grade first, due to their Administration Skills.  Intelligence Heroes are often called "Magic" Heroes, and Agility Heroes are called "Physical", while Strength Heroes are referred to as "Tanks".
