In a Boss Battle, you must challenge a stronger boss than that of a main quest to obtain rewards.
There are two types of Boss Battles: the "Solo Battle" for a single adventurer and the "Multiplayer Battle" where you must cooperate with other adventurers to defeat the boss.
If you choose the latter,
you must create or participate in a room to be with the other adventurers.
Once the required number of participants has gathered, the battle will automatically start in 30 seconds.
For an adventurer who is not ready to fight yet, the battle will be set to auto mode.
If the host who has created the room and the participating guest are following each other,
the latter's stamina won't be consumed, and if only one of the two is following the other, then only the half of the guest's stamina will be consumed.
Stamina won't be consumed for any guest who has participated in the battle upon receiving a assistance request, regardless of their following/being followed by the host.
In a Boss Battle, Boss Boosts can be used to obtain much more rewards.
