Wakamo is a Combined Operation boss for this event, with two separate encounters: Wakamo (Swimsuit) and Hovercraft stages.
The encounter has 3 difficulties, freely selectable by players. Each victory reduces bosses' server-wide HP pool; once HP drops to zero, Decisive Battle version of the encounter can be played to obtain extra rewards (claimable once only).
Each attempt against the boss will cost 10 tickets. If the boss was not defeated during the fight, reentering with another team costs 1 ticket.
If players have not reached the maximum owned limit (40), 1 ticket will be granted every 30 minutes.
Players can purchase tickets for prices starting at 5Pyroxene.
There is no 1-hour time limit to challenge the boss and no sweep mechanic unlike regular Raids.
Even if the Boss cannot be defeated within the time limit, it is possible to re-challenge the boss with the Boss HP still the same from previous run; tickets will need to be used to enter the fight again.
All 3 difficulties have separately tracked states and will not be reset until the Boss of that difficulty is defeated, so should you challenge the boss on other difficulties while still mid-run, you will still be able to resume fight at the old difficulty later.
Ex: You attempt boss difficulty Hard but fail at 20% HP, then you decide to challenge Normal and defeat it; if you challenge difficulty Hard again, the battle will resume at 20% where you last failed to defeat it.
Tickets will be not be refunded if you forfeit mid-battle.
It is possible to use the same team to challenge the Boss again.
Friend/Club Assist function is available, Normal, Hard, and Very Hard difficulties allow use of 3, 2, and 1 rental student per run respectively. Any given unit can only be rented once per day; assist records are cleared during the daily server reset.
When the ATG gauge value is MAX, enter missile runaway mode to destroy the resort. Player will be defeated if the resort is destroyed. Hovercraft becomes immortal during missile runaway mode. When the missile runaway mode ends, hovercraft will fail and enter Staggered state. During the Staggered state, the amount of damage taken increases by 200% and Critical Resistance is decreased by 100%.
