Intro
This guide is to hopefully direct you on what skills to upgrade with your current Nikkes!
The rating system weighs mostly upon if said unit is good and if the skills scale well at early-late investments and worth investing to. It also slightly takes into account if the unit could be part of your main team despite maybe being an off-meta unit.
Skill book consumption is listed as well as cumulative books consumed at said level, denotated by numbers put in brackets; Ex. (xx) for your convenience.
Use CRTL+F and type in the name of the Nikke you wish to search up for easier usage of this guide
Other SR units not mentioned are only used for early chapters and you do not need to invest in their skills to get through the chapters, nor will it help. DO NOT upgrade other SR units skills, save the resource for good SSR units instead. If you really have/want to upgrade them, it should be only be until level 4.

Skill Income

Here are the expected skill books you can get daily after completing certain simulation rooms. the max total is
- I = 80 skill manuals, 40 burst manuals
- II = 60 skill manuals, 30 burst manuals
- III = 16 skill manuals, 8 burst manuals, 30 code manuals
Events shops are also expected to give:
- I = 160 skill manuals, 80 burst manuals
- II = 120 skill manuals, 60 burst manuals
Books are rather very limited so please invest in your skills wisely. Please do plan ahead as they are very important sources of your DPS output.
Additional Income: Simulation Overclock Event
The max total rewards from this game mode is:
| Skill Manual I | Skill Manual II | Skill Manual III | Burst Manual I | Burst Manual II | Burst Manual III |
| x168 | x124 | x56 | x84 | x62 | x28 |
This around 4 Days~ worth of Sim room rewards if the Commander completes core ratio 25.
Investment Intro
Before heading to the list. As you can see, leveling up to skill level 4 does not take much books at all. It is recommended for newbies to at least skill level 4 your core team units for the combat score rating boost even if the skills may not be too great.
Investments explained
Budget investments are the first “thresholds” you want to reach first. Once reaching this point, the Commander can focus on other Nikkes as fully focusing books on one Nikke is not recommended due to the exponentially increased skill book cost, with still linear increases on what the skill does.
If a selected Nikke does not anything listed in the budget skill investment section, and they’re part of your main team, assume the budget is always 4/4/4 unless stated in the Recommended skill investments. This is due to them not being placed very high in the meta and not worth fully investing towards (Level 10 skills), it would be best to save books for future Nikkes.
Recommended Investments are the recommended thresholds once you have more books to spend, and wanting to fully invest in a Nikke due to their strengths in certain game modes / where they place in the meta.
Investment Order is simply which passive to level up first when comparing the two. Burst is not included as Burst skills use completely separate books.
Note: Skills stated to be recommended to be level 1 can be upgraded to level 4 for CP padding, as skills do increase CP (Combat Power)
Investment Priority Explained
This Section heavily considers where certain Nikkes lie in the meta.
Low – Nikkes that are not worth / may have rare scenarios where skills are impactful in battle/ Lower levels are already sufficient enough. Not worth planning skill books to invest towards to. .
Mid – Nikkes with skills that have a good impact in battle, and used if they simply don’t have the meta options.
Mid-High – Nikkes with Skills that can have major impact but only in niche scenarios.
High – Nikkes with Skills that have major impact in battle or are very good at their Niches/ Use case scenario. Skill levels can be raised up to 7 until more priority Nikkes are finished being raised. The user can consider raising them higher after.
Highest – Nikkes with Skills that are extremely potent in battle, usually universal and benefits every team. Namely DPS skills/Bursts, damage taken debuffs, or attack buffs. Raise these ASAP after getting your main team Nikke’s mid – high priority skills at around level 4 or 5 at least, as skill book costs get exponentially higher after.

Great guide to know how to start investing these upgrades, really thank you.
But… Did I miss something on Soldier EG?
Absolutely a beast.
Hahaha
Considering diminishing returns and massive leveling costs, this is really helpful. Thanks y’all
Where is Neon?
Soildier EG is a beast? so we have to make her lvl 80:?
It’s a joke in case you don’t recognize it, R units are almost never ever used in this game
Where is N102? :<
Her skill 1 and skill 2 not worth considering. Only upgrade her burst to lvl4, and focus investments on your main DPS units instead.
Ok thanks!
Himeno priority skill ?
why not show all nikke priority skills? Where is SR Nikke? Even if the SR Nikke is useless, at least still display it for comparison. This is an incomplete list of Nikke skills.
Yeah, I agree. Especially since in other locations sometimes SRs are recommended as replacements for SSRs if you don’t have them.
* Cries in Neve *
Sin and Quency ?
Guide is missing Sin / Quency
Will i need to play each level for the max output or is playing the highest level once a day enough?
Playing the highest level once is enough
Quincy? Guilty? Sin?
Where is Anis?
Anis is balanced, you have to up all her skills at the same time, cause she is meant to function with everything, as every skill covers a certain aspect of her gameplay but lacks another, which is couvered by her other skill… so on so forth.
this needs to be updated ASAP, especially with Dorothy coming
Where is Quency and Sin ?????
They’ve been on the list for a few weeks.
Hi, with the actual rework of SMG mechanics, maybe soline would have a better rating in general?
Rei Skill Priority ?
It’s been months and Nihilister skill priority guide is nowhere to be found
That’s because Nihilister is dog water. Do the basic needful and get her to 4/4/4 and 5/5/5 at the maximum.
wowow ur very in depth i appreciate ur analysis
she should still be up there
her character page has this information but not this page for some reason:
Skill 1: 4.5
Skill 2: 3
Burst: 4
so according to the guide, you can upgrade skill 1 and burst above level 4 if you really want, but its not recommended to upgrade skill 2 any higher than 4
Rosanna Skill?
Marry: Bay Goddess and Neon: Blue Ocean skill priority?
Summer units please
From D banner never update again ?
how should I invest SR Anis for PVP?
Definitely! I’ve been using her and constantly been number 1/2. Shotgun units are insane in pvp
I believe he was talking about the 4*/ Purple/ Rocket launcher variant of Anis.
I wouldn’t invest more than level 4 skills as her actual skills serves little use.
Yup, I was talking about rocket launcher Anis. I heard that she was quite good in PVP even though being a SR unit
do u think anyone is gonna remember rei for long enough to add her skill priority to this list or nah
She’s only worth leveling for mlb if you got her during the event. If I remember right, her skill 1 is the only useful part of her kit and even that should only go to level 4
What about S.Helm?
just noticed there is no skill ratings for Rei
There are 2 Julias on the list and I think second one is supposed to be Laplace since she doesn’t have a skill rating.
Mast and Maxwells SR values were entered in place of each other as well.
Corrected. Thanks!
does 1.5 means i can go either level 1 or level 2 for that skill?
1 minimum, 4 maximum
it just means that you prioritize other skills over that one, for example you would invest in a skill listed here with a priority of 4 before you invest in the 1.5 skill
Thank goodness Soldier EG has finally been removed. Private jokes that confuse the intended audience shouldn’t be in a guide.
it was so obviously a joke that if you fell for it you deserve to lose your skill manuals
i really really hoped we can get unlimited skills reset on anniv… Need that badly for my nikkes 🙁
Sakura’s skill 2 also helps taking down destructible projectiles and Thomas’ missiles are SO ANNOYING, tankier than those pesky elites feels like
I hope you put an option that makes the list order from the highest to the lowest
to make it easier to compare
not really sure what you mean but I just use the (Ctrl + F) function to look for specific things with a keyword plus the list in a Alphabetical order is a lot better than released order
Still no guide for rei and sw innocent days?
Innocent Days skill kit is all around pretty great. She can rival Scarlet at 10/10/10, but if you don’t want to invest that much, I’d give more priority to skill 3 and probably level 1 and 2 evenly whenever you have the spare mats (which is probably never with how stingy this game is)
What is an MX team?
Don’t know if you got this answered already, but I’m guessing MX stands for Maxwell?
Why are both Snow White: Innocent Days and Rei both excluded? They may not be rollable units, but I still want to see wether or not they’re worth the investment. They’re still technically SSR’s, so they should be listed.
SnowWhite, is good, if you don’t have Winter Ludmilla or Modernia, that is.
still didnt have a skill priority of scarlett black shadow ?
Where’s Scarlet Black Shadow????
Still missing:
– Mica: Snow Buddy
– Scarlet: Black Shadow
– Snow White: Innocent Days
Still missing:
– Mica: Snow Buddy
– Scarlet: Black Shadow
– Snow White: Innocent Days
-Leona
Hopefully we can see Moran and maid priv on here later as well
where snow mica
where black scarlet
where smol white
where leona
where moran
where titty privaty
ur slackin valkkin
Your changelog makes no sense Valkkin. The two planned items will add to maintenance work and you can barely keep up with keeping the list up to date. It’s missing units that were released months ago get your $sh!t together.
this guide is well-intentioned but it’s better to centralize this information.
there’s correlation with a Nikke’s tier list placement and her skilling priority, and the profile widgets on the tier list seems to support skill level recommendations. so just maintain that instead of two pages.
WHERE SCARLET BLACK SHADOW? Swear to god if I knew where to find this info I’d put together my own website.
Hello could you please add Leona who is currently missing after the last big update, I believe is the only character missing. Thank you
“Soda’s burst is not even worth considering upgrading.” – then why is it at 4 o.o – I don’t get comments like this with contradictory skill investment suggestions D: , but thank you guys for your hard work / guides!
getting to level 4 doesnt really cost anything, everything past level 4 costs skill manual 2 and code manuals
Scarlet BS doesn&t have her priority in bold and blue even though is is marked as a @highest priority@
Great guide but the most recent update made browsing it on mobile even more of a nightmare than was the case before. It’s bad enough that this is absolutely devastatingly cancerous in its design and relentless spam, it’s brutal to try and navigate on mobile!
Would also be helpful if you could sort the Skill Priority page by priority ranking and all the other sorting tools as found on on the Tier List page.
Also I don’t know if it’s by design but the pages on this site constantly reload on mobile – I’m assuming because of the cancerous levels of spam. I understand you provide an ad-supported service but it’s enough to want me to make a competitor site with streamlined UI and less cancer, lol.
