Basics - Heroes

The Heroes screen is where all the hero management occurs. From here you can adjust your party, as well as equip, upgrade, train, and fuse your heroes. This is where you will most likely sink tons of gold into upgrading.

At the top-left of the screen you will see your current hero deck. When you start you will only have access to one hero deck. Additional hero decks are unlocked at levels 6 and 15. The first two heroes equipped will be at the front of the battle, while the last three will be in the back. It is recommended to equip heroes with high Defense and Health in the front, as heroes in the front are more likely to be attacked.

From the top-right, you can see your current gold, carats, and the number of heroes you currently have. You may sort your heroes in whatever order and can set your party leader with the crown button. At first you can only hold up to 20 heroes, but you may buy more hero slots by tapping on the icon at the far top-right.

Heroes are ranked by rarity represented by stars(★) from 1★ Normal up to 6★ Legendary. The higher the rarity, the harder it is to obtain, and the stronger the hero will be once fully leveled and upgraded.
Heroes start off at level 1 with a max level of 30. They have four base attributes and two skills each which determine their effectiveness in battle.

Attributes:
Attack Damage - Attack damage is directly linked to the heroes offensive capabilities and how much damage they are able to deal. In addition to normal attacks, any skill that also does damage will also rely on this attribute.
Defense - The defense of a hero determines how much incoming damage will be negated when they are attacked.
Health - The maximum health of a hero. All heroes start off at full health at the beginning of the battle and will die once their health reaches zero.
Dexterity - This attribute affects when a hero will attack and how often they will attack. The highest dexterity hero will always attack first at the start of a battle.
