Ranked Co-op is here! It is extremely recommended that you play with friends or guildmates to better coordinate team comps and strategy if you want to have a high placement in the rankings. Unfortunately, this does not apply to low leveled players as after stage 9, Gatekeeper will more often than not just one shot the team (but the mechanics do stay the same though). This guide is aimed towards players who want high scores for flex purposes or higher placements in the leaderboard, or just for players who want to have fun while knowing how the boss mechanics work.
Boss Mechanics
Shield
Bring at least one water unit to deal with his bubbled QTE circles. Non-water units are unable to hit through his shield that he covers himself with, showing hits toward Gatekeeper as “Immune” while water units do not have such problems.
Stage 9 > Transition
Red circles are your enemies, white circles are your friends. DON’T hit the white circles or time out, you’ll get heavily punished for doing so as the boss throws a literal sun at you which can easily end runs.
Rings
These 4 rings (up, down, left, right of Gatekeeper) are the consistent damage dealers from the boss, If you don’t get taken out by failed QTE’s, attacks from these will. They become extremely tanky beyond stage 9, and deal pretty damage as well. Destroying these rings will reduce the amount of damage Gatekeeper deals. Keeping 1 ring alive is recommended if you have trouble surviving, as destroying all rings will have all the rings respawned shortly after.
You are able to and should reduce the HP of all rings before they become extremely tanky after stage 9 transition (Destroyed rings will be respawned).
Leaving all rings at very low HP and then finishing off 3 rings, leaving 1 ring alive after transition will greatly improve survivability.
Meteors
It is recommended to use AOE burst (Scarlet/Privaty) to get rid of these, face tanking meteors will cause DPS loss as the Nikke’s hit by these will suffer a permanent 5% ATK debuff.
These Meteors can be i-framed by most Nikkes, simply take covef right before they hit if the team doesn’t get the chance to wipe them out.
Team Comps (Week 1)
Make sure aim assist is turned on so players have a much easier time hitting core.
Christmas Ludmilla Team (Elemental Damage Team)
This team assumes the Commander has Elemental Damage Overload Rolls on Christmas Ludmilla. If no Elemental rolls are present, use your best DPS’s instead as MG’s have drastically reduced Fire rate on co-op (30 FPS), resulting in less damage.
- Liter can be substituted by Dorothy (High ED rolls), Volume, or D: Killer Wife
- Tia/Naga can be substituted with Blanc/Noir
- If duos are not available, Marciana can be used instead for healing
Pierce Team
Next best team. As there are not much Water DPS’s around, using the Meta snipers will very much do. Although since 2 Pierce Nikkes are being slotted her (non of which is water), Dorothy is needed as the CDR Nikke
- Dorothy can’t be replaced as she’s the sole QTE breaker of the team. Tia Naga would have to go if replacing her, which will severely cripple the DPS in this team
- Blanc/Noir is still usable, however unoptimal due to them refilling ammo for Dorothy + Increased max ammo, which gimps her skill 1
- Red hood can be replaced with Alice
Non Duo Team
Not exactly ideal, but not everyone has the Duos. Since there’s a lot of possible mix and matches can be done, just gonna jolt down a few ideas
- Shotgun Team With Tove / Leona / Healer (Tove + Leona are water elements)
- Liter, Novel, DPS, DPS, Helm (Helm Is Water)
- Dorothy,Marciana, 2x Anis: Sparkling Summer, Privaty
- Any team with Emilia, Make sure the rings are alive for her burst, so she can hit multiple times.
- Literally just have 1x Water type in your team, and shove in best DPS’s and available support + healer.
It’s more than easy, people are just bad. I mean really bad…
