Intro
Co-op this event will be available from 12:00:00 December 1, 2023 (UTC+9) to 23:59:59, December 3, 2023 (UTC+9).
Simply navigate to “Coordinated Operation” in the events tab and start searching for a party or create one with your friends.
Mechanics
When the battle starts, Modernia is already threatening the team with her laser Attack. Destroy her core to prevent this. One AoE laser (past node 8) will one shot cover. The main threat of Modernia is her QTE’s and core, failing to destroy either will proc a teleport phase or a team damaging AoE + stun.
Destroying both wings is recommended as the bombs hurled towards the Nikkes do debuff the Nikkes ATK on hit. Iframing or destroying the bombs are also plausible options.
QTE
The QTE’s simple. No Gimmicks or anything, although they do kinda serve as “DPS checks” since they are rather tanky. When failing a QTE set, the team is either punished with a team damaging sword swipe or a more annoying teleport phase.
Modernia opts for a sword swipe if ANY of the wings are present / not destroyed when failing a QTE.
When there are NO wings present / both wings are destroyed, Modernia opts doing a teleport phase instead.
Modernia’s core and wings occasionally respawn during the fight after around 6 successful QTE breaks , preferably the team wants to have wings present to prevent teleport phase if they’re unable to to consistently break QTE.
Team Comps
Nikkes with hard hitting bursts might look enticing because of the parts, there is an interesting team comp going around because of a new Nikke and element weakness of this current co-op boss. These team comps mostly revolve around Tove, Noir, and Guilty.
Recommended Units
Burst 3 units : Snow white (Pierce), Maxwell (Pierce), Noir (QTE breaker, Element weak), Scarlet, Modernia
Burst 2 units : Guilty, Blanc (w Noir). Naga (w tia)
Burst 3 units : Tove (Shotgun team), Liter, Dorothy , Tia (w Naga)
Best teams so far
Shotgun Team
Pretty much the best team comp as of right now assuming each shotgun Nikke has lines of elemental damage. However this team is limited by the RNG nature of Tove due to how her mechanics and stacking works while needing high skill levels (level 8+), damage may vary quite a lot.
One Guilty slot can be replaced with Dolla due to unavailability or if the Guilty in question is too weak to do deal meaningful damage. Some full bursts may be needed to saved for QTE phases to destroy core when it spawns.
Pierce Team
Since core respawns every 6 (?) QTE breaks, this is perfect for burst pierce type characters. Although not as effective as the shotgun team due to the elemental damage, this team does not require having Nikkes being stacked with elemental damage overloads. Burst timing is required though and needs to be coordinated with the team.
Maxwell can be the secondary pierce / core breaker or if QTE DPS is more of a problem, a more consistent DPS such as Modernia or Scarlet can be slotted instead.
Bread And Butter Team
Classic bread and butter team, but in Co-op. Bunny twins can be replaced with school girls for higher core breaking potential, but 2 Scarlets would be needed to be slotted in instead. This is due Modernia being forced to burst.
