Harmony Cubes - information

Harmony Cubes are a piece of equipment your NIKKEs can wear and only one Cube can be equipped at the same time - though once you upgrade the Cube, you are able to equip it on multiple NIKKEs.

Currently there are 6 available different Harmony Cubes, each with an unique buff that improves one of the NIKKEs stats.

How to unlock Harmony Cubes?

To unlock the Harmony Cubes you need do conquer the Lost Sectors. Here's the order you will unlock them:

• Assault Cube - Lost Sector 1
• Onslaught Cube - Lost Sector 2
• Resilience Cube - Lost Sector 4
• Bastion Cube - Lost Sector 7
• Adjutant Cube - Lost Sector 9
• Wingman Cube - Lost Sector 11

How to upgrade the Cubes?

To upgrade the Harmony Cubes you will need special items called Batteries. Each Cube needs different Batteries to upgrade it and you can obtain them either from Lost Sector or from the Union Shop.

Here's a list of the available Harmony Cubes:

Assault Cube

Assault Cube increases the character's Hit Rate and starting from level 5 also gives additional damage as strong element.

This Cube is suited best for characters that use SMGs or Shotguns as they benefit the most out of the buff. Also, Modernia can abuse the cube to get near-permanent uptime on her S2 ATK buff (but if you have Overload gear with Hit Rate, you don't need the Cube anymore).

A few example characters that use the Assault Cube:

*Modernia loves Assault Cube until you get overload gear on her.

Onslaught Cube

Onslaught Cube increases the character's Charge Damage and starting from level 5 also gives additional damage as strong element.

This Cube is suited best for characters that use Sniper Rifles or Rocket Launchers as those weapons needs to charge their shots, so the cube gives them more damage.

A few example characters that use the Onslaught Cube:

Resilience Cube

Resilience Cube increases the character's Reload Speed and starting from level 5 also gives additional damage as strong element.

This Cube is suited best for characters that have long reload speed animation and the cube lowers their downtime by quite a lot - and this translates to a DPS increase. Also, characters that use the last bullet mechanic benefit from the cube a lot.

Overall this is the most universal Cube that works on most characters.

A few example characters that use the Resilience Cube:

Bastion Cube

Bastion Cube recovers the ammo while you're shooting and starting from level 5 also gives additional damage as strong element.

This Cube is suited best for DPS characters who use Assault Rifle or Machine Guns as the ammo recovery allows them to keep shooting for longer before needing to reload which translates to increased DPS. At level 1, every 10 bullets you fire will magically 'load' your magazine with 1 bullet - while this doesn't sound that great, once you level up the Cube, the recovered ammo amount increases to 3 bullets per 10 shots fired.

A few example characters that use the Bastion Cube:

Adjutant Cube

Adjutant Cube increases the character's Charging Speed and starting from level 5 also gives additional damage as strong element.

This Cube is very similar to Onslaught Cube and it's suited best for characters that use Sniper Rifles or Rocket Launchers as those weapons needs to charge their shots, so the cube allows them to do it faster. Though in most cases you still prefer to use the Onslaught Cube as it has better numbers.

Overall, the Cube is more popular in PVP because there you need to reach first Burst before the enemy to win.

A few example characters that use the Adjutant Cube:

Wingman Cube

Wingman Cube increases the character's Magazine Size and starting from level 5 also gives additional damage as strong element.

This Cube is good generic cube as nearly everyone benefits from larger magazine size (only characters that rely on last bullet mechanic should stay away from it). Sadly, while initially the Cube sounded great, once Overload gear came into play, a lot of players turned away from the Wingman Cube and went back to Resilience/Bastion Cubes. Why? Because Overload gear can give you much much more Max Ammo than the Wingman Cube while the benefits from Bastion cube can't be replaced by anything and Resilience Cube has more uses too.

A few example characters that use the Wingman Cube:

From the 6 available Cubes, only 3 matter: Resilience, Bastion and Wingman. The other 3 have only niche uses.

For PVE, the Resilience Cube is the most universal one so you can't go wrong with upgrading and using it, but once you reach the endgame and start obtaining overload gear, Bastion will start to outperform Resilience (but not in all cases). Wingman is the third choice as it allows RL and Shotgun characters to shoot for longer, but keep in mind that in most cases it's inferior to both Resilience and Bastion.

For PVP things change quite a lot as there Adjutant Cube starts to become important for RL and SR wielders - that's because you only care about reaching Full Burst before the enemy does and every bit of Charge Speed helps with that. Other weapon wielders everything depends on the overload gear you have and we will go more in-depth into that in a future guide.

With the way the Bastion Cube scales, a lot of endgame players invest into it first - at least till they reach level 7 when you unlock the 3 bullets refund per 10 shots fired.

Resilience Cube while initially being better than Bastion Cube as the Reload Speed bonus is pretty massive, starts to fall off once you take into account the benefits from Bastion Cube and Overload Gear (you can get up to 85% Max Ammo per gear piece there which combined with the Bastion ammo refund allows some characters to shoot non-stop - like Modernia for example).

So what should you do?

Upgrading the Resilience Cube to level 3 to get the 22% Reload Speed increase (compared to 14% on earlier levels) is a pretty big jump, so it's worth to get it. But then you should turn your focus on the Bastion Cube and upgrade it all the way to level 7. Only then you can either return to Resilience Cube or start working on Wingman Cube (but imo it's still better to continue working on Bastion and Resilience Cubes instead).

If you compare Bastion and Resilience Cubes on the same level, in most cases you will get nearly exact DPS increase - but this is only true whenever you compare the characters with only the Cubes equipped. When other buffs and most importantly, the Overload gear are added to the equation, the Bastion Cube starts to take over the Resilience Cube.

Why does it happen?

Because when you keep stacking Reload Speed you quickly start to hit diminishing returns and there's a lot of sources of Reload Speed buffs (Privaty, Admi for example). While currently there's nothing in the game that can replicate the benefits gained from the Bastion Cube - the ammo refund.

TL;DR:

• Resilience reduces downtime, which means more bullets fired within a time window,
• Bastion increases uptime, which means more bullets fired before a reload.
