Changelog
• Added Section for batteries in regards to Union raid/ Solo Raid
Intro
Cubes are obtained from Lost Sectors, finishing all lost sectors will at least give enough mats to level 2 every possible cube, the rest are obtained through Union shop. Union shop currency is obtained via union raids and placement. 10 Batteries are worth 2000 union chips. There are 3 cubes that will get used more often that others. Resilience, Bastion, and Wingman. These cubes give reload speed, ammo refund and ammo capacity respectively. The other cubes are pretty much situational and/or for stat purposes.
Any units not specifically listed means that they are not of priority to give the cubes to or do not have any notable special interactions with said cube. If the User does not have any units that is mentioned, read the cube overviews and make a personal judgement on which Nikke’s should a cube be placed on.
The “Damage as strong element” Is an addition to damage against enemies that are weak against the Nikke’s element with the equipped cube. (ex. Scarlet has equipped cube that is level 5 which is the level said passive unlocks, she will do additional damage against lightning weak enemies in addition to the 10% base additional damage, so 10 + 8.48% = roughly 18.48% more damage towards element weak enemies)

Batteries
An additional amount of batteries can be obtained in the Union raid shop. Currency from Union raid can be obtained by participating in Union raids, and the amount depends on what ranking you get.
In Solo raid, batteries can be obtained by attempting and successfully beating the raid boss. Batteries depend on the level of the raid boss defeated. the maximum amount of batteries that can be obtained is 6x per day, and is randomized.

Cube Effects
Resilience
This cube is the best cube at early – late game as it is very versatile. Every core dps will want to hog this cube. Resilience increases reload speed, which is vital for units such as Scarlet, SG’s, RL’s, and other units that have long reload times.
Units listed above are units that benefit greatly from this cube. Pepper may look like the odd one out, but if the user uses Privaty + Resilience cube with manual play, Pepper’s healing dramatically increases via her last bullet skill; Fast reload + Mag debuff procs her last bullet more often because of lower bullet count and faster reload speed.
Bastion
This cube is very good for late game units where Users have Max ammo + rolls on their Overloaded gear. Bastion Cube can outperform Resilience cube in certain scenarios, but more often than not, Resilience cube is a slightly better comfort/versatile pick for all Nikke’s with the exception for MG Nikke’s. As MG’s also want to avoid reloading at all costs, for there is a wind up time for MG’s, which reduces DPS.
Scarlet (with at least =>50 Ammo), and Modernia benefit from this cube quite a bit. other MG’s or AR’s of your preference will also work with the bastion cube. The reason why this cube is good for MG’s and AR’s to an extent is because the larger the mag a unit has, the more benefit this cube gives as refunded ammo is able to refund itself in a sense.
So if Scarlet is at 50 ammo, this will refund 10 bullets at bastion level 2 per mag, the refunded 10 bullets is enough to refund another 2 bullets.
However, if running Reload teams (Privaty or admi), Resilience straight up beats Bastion.
Wingman
An ok cube for mid game purpose. Mostly used for SG’s. Can be used for core DPS’s units but not as a first choice option.. The reason why it’s not better than Resilience or Bastion is because the max ammo is additive and not multiplicative. In other words, if you already have Max ammo rolls from overloaded gear, it does not multiply the ammo count, but rather just adds the base ammo to the magazine (Ex. Scarlet base ammo 20 x (Overload Max ammo % + Wingman ammo %)). meanwhile Resilience and Bastion are effectively final multipliers for ammo count.
Adjutant
A situational cube used by units such as Alice, Snow white, and even Rapunzel. Since Alice has high charge speed when you have high skill investments on her, and even more with Overloaded gear with charge speed rolls, every charge speed towards 100% counts. getting 100% charge speed on Alice is convenient as Alice is able to have full charge on frame 1 when she is able to fire, increasing her damage ceiling if the User can play her optimally; this can be the clutch for her if needed, otherwise User can use Resilience cube on Alice instead.
Snow white Benefits from this if using her alongside with Liter and/or Novel, as the user is unable to fully charge her burst to 1000% in under 5s, any longer than 5s and the buffs of Liter and Novel will expire. In other words, using adjutant cube for Snow white enables her to squeeze some extra charge % in her burst before said buffs expire.
Putting this on Rapunzel slightly increases her healing output, although Putting Resilience on her will fare better for her.
Assault
Mostly used for SG’s or stat sticks. Enables Low accuracy weapons such as SG’s, SMG’s and to an extent AR’s to hit targets slightly further away and to hit rapture cores slightly better. Using Resilience (more priority) /Wingman cubes on SG’s is still recommended if they are available to be used.
Onslaught
Mostly used for RL’s or Snipers. It is also used for Maxwell for a slight bump for her Burst damage. Onslaught is also usable for Snow white assuming user is not running Liter and/or Novel team, otherwise use Adjutant for Snow White. Onslaught cube does not increase the amount of time it takes to charge up Sniper or RL damage meter, this rule also applies to any bursts that has a charge mechanic (Currently only Maxwell and SW); Charge damage increase is also additive and not multiplicative (For ex. Snow White can charge up to 1000% via her burst, an Onslaught cube that gives 3.81% charge damage boost will increase the charge up to 1003.8%, not 1038.1%).
Relic Quantum Cube
Mostly only used in PvP. The burst generation added from this cube is low, it won’t really be noticeable in normal campaign/ Boss runs. In fact, running Resilience/Bastion/Wingman Would generate more burst gen overtime than this cube is able to just because of increased uptime. Therefore, it is only used in PvP as whoever bursts first pretty much wins there. Prioritize on giving this to RL, or SG’s in arena.
Note: Recommended units below is STRICTLY for PvP usage only.
Cube Upgrade Priority
It is recommended to at least Level 3 Bastion, Resilience and maybe Wingman first if wanted. Then focus for Resilience level 7 for late game purposes, then level 7 Bastion.
Recommended Cubes On Characters
Note: Assume Resilience is best in slot when ANY reload buffs/teams are apparent in team comp. Also assume at least skill level 2 (Cube level 3) for all cubes.
Note 2: Make sure to Read Extra notes if there is any as cube priority might change depending on team comp/ situation and WILL be listed if so.
Note 3: Assume This is Pre – Overloaded Equipment unless stated in extra notes. Recommendations should mostly stay the same for Post Overloaded equipment.
Last Note: Always prioritize giving your Resilience / Bastion Cubes to DPS’s, Otherwise use other cubes for supports if they’re not available. With the next best choice being wingman unless stated otherwise
Quick Weapon Archetype Explanations
- •Why does Rocket Launchers/Sniper Rifles want Resilience/Bastion Cube instead of Onslaught, Adjutant or Wingman?
-More Uptime/Less Weapon Downtime beats out the tiny DPS gains of Onslaught and Adjutant, also helps burst generation when manual shooting. Wingman Only gives 1 Additional Ammo.
- •Why Doesn’t Most (Clip) Shotguns want Wingman as Secondary option instead of Bastion?
-Shotguns have 9 base ammo, the ammo refund will start at the next full reload, Refunding 2 ammo when there’s only 1 bullet expended, effectively halving the efficiency. Meanwhile level 2 wingman is enough for 4 bullet reloads per clip instead of 3. The bastion cube scenario can easily be mitigated/avoided if one simply has Liter. However, both should perform similarly, Wingman simply has less risk. Of course, Overload equipment max ammo rolls completely negates this and bastion cube would be preferred. - •Why Does Machine Guns want Bastion or Wingman instead of Resilience?
-MG’s technically have 2 “reloads”. The actual Reload and the wind-up time. Resilience Affects base reload time but not windup time, meanwhile Bastion and Wingman has more firing uptime therefore also reducing the amount of windup times needed in a match.
| Character | Best in Slot | Secondary Option | Extra Notes |
| Resilience Cube | Bastion Cube | Post Overloaded equipment with 1+ Max ammo rolls, Bastion Becomes Best in Slot | |
| Resilience Cube | Bastion Cube | Post Overloaded equipment with 2+ Max ammo rolls, Bastion Becomes best in slot. Adjutant can be considered if Charge speed is at 98% (achievable with overload rolls/Maxwell charge speed) and the user is fast at clicking. | |

| Bastion Cube | Wingman Cube | Wingman is especially wanted for Non-Overload equipment players, as she reduces her own max ammo. The buff provided by wingman doesn’t get affected by the ammo down, which is great. HOWEVER replace Wingman cube when overloaded gear is obtained and 1+ Max ammo roll. Assault Cube not really needed as it’s almost 100% Uptime with a CDR unit anyways. | |

| Bastion Cube | Resilience Cube | Bastion is BiS with Noir as she provides ammo refill and increased ammo buffs / She reloads very fast anyways. | |
| Resilience Cube | — | She Does NOT want ammo cubes when not using her manually, as she wants her Max HP buff to expire before renewing it, causing her to heal. The only window where she can heal on auto is when reloading (Heal still applies even with Resilience), therefore she wants to run out of ammo quicker. | |

Charge speed is not additive, it is multiplicative. The only charge speed buffs that are additive are Simulation Room charge speed buffs. It’s not possible to get 100% charge speed on anyone outside of Simulation.
Charge speed can be 100%’d outside simulation room via Alice paired with Maxwell (which is done very often anyways), Yuni and/or Overload gear charge speed rolls. Which would work the same as if user was to have 100% in simulation room, Full charge at frame 1 when you’re able to fire sniper rifle.

what’s your setup?
It is possible. My Alice has a 100% charge speed with 2 OL gear giving 7% charge speed in total, skill level 10 4 10, and maxwell support with skill level 10 4 10. Let me just say its a pleasure to hit over 1 million piercing damage with fast shooting trick.
Just a heads up, this guide can’t be found anywhere on the drop down menus just in case it gets dropped down enough off the front page to be a pain to find later on.
I know you’re busy shitposting on discord lol 🙂
Keep up the great work.
im not that far into the game yet but i was fuckin about in the union shop and saw a battery for a cube i had never heard of before, “relic quantum”
guide needs update?
I just noticed lv 6 cube requires 50! batteries. I assume lv 7 requires even more. Is that even realistic???
No information for new Cube, Relic Quantum Cube. Update pls. Tyvm.
