Heroes can be purchased and upgraded in the Heroes Altar. You can buy a Hero four ways, using different resources:
- 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.
- 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) are smaller than of it being a shardable hero, however there is not enough data available for this to be statistically proven. 
- Shards : Selection, you can choose which hero you wish to acquire 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. There are 3 kinds of Hero Cards that are based upon the types. These are Hero Card (Green color that hires random Ordinary heroes) Elite Hero Card (Blue color that hires random Elite heroes) and Legendary Hero Card (Purple color that hires random Legendary Heroes). The other type of Hero Cards which is Sacrifice Card (Brown color that hires random Sacrifice Heroes) are considered as sacrifices or Skill experience card.
By default, you’ll be in Hero Mode when entering the game.
Tap the button to switch to Item Mode. When switching between modes, a pop-up message will appear to confirm the change. The icon and colors will also change to reflect the corresponding mode. In Item Mode, everything hired from the three hiring methods will be stored in the Warehouse as items.

The revival time is calculated in seconds by the following formula:
- For heroes between lvl 1-39: Revive time = lvl * 10
- For heroes between lvl 40-200: Revive time = lvl * 15
- Each upgrade of heroes altar up to level 20 reduces the time by 3%, each upgrade 21-25 reduces the time by 2%
- lvl 100 hero takes 100 * 15 = 1500seconds / 60 = 25m to revive
- If the heroes altar is level 10, then the time needed is reduced by 10 * 3% = 30%
- That changes the revive time to 1500 seconds * 70% = 1050 seconds / 60 = 17m30s
