# How to play?

## What is Boss Challenge?

Boss challenge is a mode where you use mongen and troop to attack a creature called Boss. 

The team that participates in the battle in the Boss Challenge is counted as the *<mark style="color:red;">**invasion battle team.**</mark>*

Battle with the Boss is divided into several stages.&#x20;

Depending on the amount of damage you deal to the Boss, the Boss will transform his skills and become stronger.&#x20;

When he transitions to a new milestone, you will receive a reward. <mark style="color:red;">**You can only claim rewards at each milestone once per day.**</mark>

## Formation & Battle Mechanic Change

Formation is divided into three rows: front row, back row and middle row.&#x20;

The boss's basic skills will prioritize attacking targets in the order of **front row -> middle row -> back row.**&#x20;

**Skill RNG is now considered infinity in Boss Challenge Mode.**

The boss's ultimate skill will <mark style="color:red;">**affect all units**</mark> on the battlefield instead of just specific units.

## **Condition**

Every day, the Boss will appear with any three conditions. This ensures the diversity of Boss battles.

These conditions can be found at: [List of conditions](/gameplay/boss-challenge-mode/list-of-condition.md)
