NIKKE has a lot of Harmony Cubes and it can be confusing for new players which ones they should focus on early on to not brick their resources.

This guide aims to cover the best cubes for PVE content and clarify priority to level them up.

Before we talk about that, a quick TLDR on the cube system:

Cubes have stats, main skill and secondary skill (always elemental DMG)
Main skills stop upgrading at level 7, secondary at 15
You can get Batteries to level up cubes in Solo Raid and Union Raid shop
This is a long term progression system, it takes time for everyone

There are only two cubes you have to worry about that will work on 99% of the units in the game: Resilience and Bastion.

NIKKE Resilience harmony cube NIKKE Bastion harmony cube

Resilience provides reload speed, which works on ANY unit in the game. More uptime shooting = more damage.

Bastion is basically ammo “refund”, which works on most units as long as they don’t have a last bullet mechanic.

I would give priority to these two cubes for new players to at least level 7.

After that, you can take either of them to level 14. No need to go to max level (15) since you still get batteries on Solo Raid regardless.

Thankfully, we have a few cubes nowadays that are pretty good for endgame, mostly Solo and Union Raids.

New players should NOT worry about these until you have both Bastion and Resilience at level 14.

NIKKE Pierce harmony cube NIKKE Rupture harmony cube NIKKE Destruction harmony cube

Pierce fills the niche of pierce characters like Red Hood Red Hood Tier 2PilgrimIronBurst 1Burst 2Burst 3All BurstsSniper RifleAttacker , Snow White Snow White Tier 3PilgrimIronBurst 3Assault RifleAttacker and a lot more units in the current meta that can take advantage of this.

Rupture fills the niche of true damage characters like Chisato Nishikigi Chisato Nishikigi Tier 1AbnormalIronBurst 3SMGAttacker or Ein Ein Ein Tier 2MissilisElectricBurst 3Sniper RifleAttacker .

Not as many units can take advantage of this cube, but it’s still worth considering to level up long term.

Lastly, Destruction can be used on ANY character as long as the boss you are facing has parts, since it increases the damage done to parts.

The last cube I can recommend for PVE content is Quantum, since it increases burst generation for the wearer.

This works pretty well on pure support units that deal no damage and have “bad” burst generation weapon types like Liter Liter Liter Tier 1MissilisIronBurst 1SMGSupporter or Helm: Aquamarine Helm: Aquamarine Tier 2ElysionIronBurst 2Assault RifleAttacker .

I would only work on Quantum cube IF every other cube mentioned previously it’s at least level 7.

Any other cube, in 99% of the situations is not really used.

You can slowly get them to level 7 thanks to Solo Raid random drops, but I would not use Union Raid currency on them.
