About This Game

Heroes need life!
All damage you deal will be converted equally into the hero's life
Recruit your mercenaries, Combine your bonds, choose your treasures, and select your adventures
To build an invincible army to defeat powerful enemies!

Recruit a mercenary each round. (You can also choose not to recruit - it's up to you!)


Then, click to start the battle! There are 20 positions on the field, and mercenaries will appear randomly. After appearing, mercenaries will launch one attack against the enemy. The damage caused by mercenaries will be converted into the hero's life.

As long as the hero's life is higher than the enemy's attack power, everything will be fine, and there is nothing to fear.
Therefore, try to increase the damage that mercenaries can cause to restore more of the hero's life! The above are the core rules.

Mercenaries have one or more racial bonds.
When the required number of mercenaries of the same race is on the field, the racial bond effect will be activated.
For example, when there are 3 [Troop] mercenaries on the field, their attack damage +2; when there are 18, their attack damage +12!
Currently, there are 24 racial bonds, and more will be gradually added in the future.


Treasures are also crucial. After defeating an enemy, you will have the opportunity to choose a treasure. Proper use of treasures will produce incredible chemical effects with the mercenaries.


The rest... is the challenge! Many maps, many bosses, defeat them all!
