Heroes are a special type of unit and are essential to successful gameplay. A Hero can fight in the Arena and is placed on a Hero Base in order to be used in Raids, Dungeons, Challenge a Boss, Heroes Trial, or Here Be Monsters.Team Dungeons, Torch Battles and Heroes Expeditions do not need Heroes to be placed on Hero Bases.
Heroes levels are increased by gaining Experience in Raids, Dungeons, and Here Be Monsters or by consuming Tomes. At every 20th Hero level, a Star level Upgrade will appear requiring Gold, Honor Badges and Fires in order for the Hero to gain additional Hero levels. Note that not upgrading star level will result in Hero no longer gaining experience.
Heroes can be inscribed to boost their attack, health and might. Only 4-Star heroes and above can be inscribed. Each star level has an Inscription cap. At every Star You can inscribe 20 level, the max level is 100 at 8 Star. From lvl 21 You can use Crests as a second Talent.
Heroes can be purchased and upgraded in the Heroes Altar. You can buy a Hero in different ways, using different resources:
- Gems : Gambling, the real numbers are only known by IGG, however a study suggests that a gem roll gives the player a 5% chance to receive a Legendary Hero, a 60% chance to receive an Elite Hero, a 10% chance to receive an Ordinary Hero, and finally a 25% chance the receive a sacrifice hero (with a 15% chance of a Gelatinous Champion and 85% chance of Crystal Ooze). The data also suggests that when receiving a Legendary Hero, the chance of it being a gem roll only hero (i.e. Pumpkin Duke, Snowzilla, Cupid, Aries, Vlad Dracula, Orksbane, Santa Boom, Pixie, and Death Knight) are smaller than of it being a shardable hero, however there is not enough data available for this to be statistically proven. 
- Honor Badges : Gambling, gives a high chance to receive a Slime or Ordinary Hero.There is also a small chance that you can get an Elite Hero and an extremely low (nearly zero) chance of getting a Legendary Hero.
- Shards : Selection, you can choose which hero you wish to acquired by purchasing it.
- Hero Cards: Gambling, gives a random hero for each type of Hero Cards. Hero Cards can be obtained by purchasing with Merits through Warehouse or by opening Storm Mesa Chests from Team Dungeons.
- Special Legendary Hero Card: Gives you Free random Legendary Heroes from the Daily Rewards which includes all shard Legendary Hero plus some Gem only heroes. (Pumpkin Duke , Snowzilla , Aries, and Cupid )
Duplicate heroes cannot be stacked, i.e. You cannot have more than one of the same type Hero fighting or defending from the Hero Bases and Hero Expeditions, but you can have duplicate heroes occupying Tower Garrisons.
Sacrifice Heroes are heroes that are used (consumed) to increase other Heroes' skill levels. They cannot be used in battles or for Tower Garrison purposes.
|Slime||Crystal Ooze||Gelatinous Champion|
Ordinary Heroes have the lowest stats, but are inexpensive and therefore good for beginners. They introduce the player into the game, but are not especially strong.
Elite Heroes have mediocre stats. However, a few of them are on par with the lesser Legendary Heroes.
|Serpent Queen||Ice Demon||Triton|
Legendary Heroes generally have the highest stats and are among the strongest of all Heroes. Some of them can only be obtained by Gem rolls (i.e. Pumpkin Duke, Snowzilla, Cupid, Aries, Vlad Dracula, Orksbane, Santa Boom, Pixie, Death Knight) or by in-game purchases (Spirit Mage, Minotaur Chieftain, Destroyer).
|Spirit Mage||Minotaur Chieftain||Destroyer|
|Santa Boom||Pixie||Death Knight|
Boss are classified as Heroes too, but on the enemies' side. They are special heroes where designated on different features of the game. They cannot be attained on any types of purchases but they can be seen on the assigned features like Here Be Monsters, Team Dungeons, and Challenge A Boss fights.
|Centaur Scout||Centaur Elite||Centaur King|
There are some heroes not yet released, but there are clues. For example, the "Pirate Captain" is on the Loading Screen V1.2.24 and 1.2.25 as seen in the image below.
In fact, Pumpkin Duke has been the new model of Pirate Captain since the Halloween event, but now there are some rumors about Pirate Captain being a completely new and different hero from Pumpkin Duke that will be released in the future.

The heroes shown below are extracted from the Chinese version of the game, but there are already pieces of them in English Version (skill, images, names...).
|Simian Saint||Juggernaut||Master Monk|
And there also glimpses of yet other characters extracted from Chinese version.
