General Information[]
Note: The following is a gist of Union Operation. However, the rules may change depending on the union event. Please check on the respective union event for more information.
Union Operation Boss[]
In Union Operation, the Union Operation Boss has a Global HP bar which will be deducted for every damage dealt by teachers everywhere. The Boss' HP is connected directly with the "Union Operation Boss. Thus any damage dealt is to be directed toward it. When the boss's HP reaches 0, a "Decisive Battle" will occur in which:
- No ticket will be required to enter.
- Teachers will obtain
PyroxeneCategory:test upon completing the battle. - Teachers will obtain even more PyroxeneCategory:test and
Ultimate Skill BookCategory:test upon completing the "Boss Complete Destruction"'.
Boss[]
There are 3 difficulties tied with the Boss (A, B, and C), and entering it will consume 1 Union Operation Ticket. Each difficulty will have its own HP and stats. Similar to Total War, should teachers fail to defeat the boss or within the time limit, its HP will be carried over to the next run and teachers will need to use another ticket to continue.
Should teachers decides to battle a different difficulty while having another difficulty active, they are free to do so.
- Example:
If teachers are battling difficulty A halfway and decide to battle difficulty B on the next round, the remaining HP of difficulty A will remain until defeated.
