NXX-OS

Players can view the System Log, Case Files, and Personnel Files for the NXX Organization here. These include ongoing NXX cases, as well as the player's completed cases from the Main Story.

Resource Requisition

In-game explanation of Resource Requisitions. Click to expand.

To ensure confidentiality of NXX investigations, please use an alias or shell company when applying for funding or resources.

A resource request automatically goes out every 4 hours for Stellin, Oracle of Justice II, or both depending on player choice. The base amount returned on each request increases as HQ level increases. Selecting both returns half the base amount for each of Stellin and Oracle of Justice II.

HQ Level	Resource Requisition	Stellin	Oracle of Justice II
1	I	2000	6
2	II	2400	8
5	III	2800	10
7	IV	3200	12
9	V	3600	14
11	VI	4000	16

Once a request finishes, the resource request rewards will take up a slot until a player claims it. A player starts off with 3 slots, meaning a player can go 12 hours until all slots are filled and no more resource requests will automatically start.

Additional slots are unlocked at Headquarters Lv. 2, Lv. 7, and Lv. 11, pushing this maximum to 24 hours, increasing rewards, and unlocking additional resource requisition options. Purchasing the Monthly Pass will also unlock an additional slot. A maximum of 7 slots are available at any given point in time.

File Room

In-game explanation of the File Room. Click to expand.

Data from the Big Lab shows a marked increase in the incidence of missing persons and mental illness cases in Stellis over the past three years. Careful analysis of these cases is necessary to discern the root cause.

Players can obtain Research Materials and Impression items through the File Room. The case levels available and the number of available case analysis slots go up as HQ level increases.

HQ Level	File Room	Cases
1	I	Unlock Level B cases. Conduct up to 4 simultaneous Case Analyses.
3	II	Unlock Level A cases. Conduct up to 4 simultaneous Case Analyses.
6	III	Unlock Level S cases. Conduct up to 4 simultaneous Case Analyses.
10	IV	Unlock Level S cases. Conduct up to 5 simultaneous Case Analyses.
13	V	Unlock Level S cases. Conduct up to 5 simultaneous Case Analyses. Increased chances for higher-tier cases.
15	VI	Unlock Level S cases. Conduct up to 5 simultaneous Case Analyses. Further increased chances for higher-tier cases.
18	VII	Unlock Level S cases. Conduct up to 5 simultaneous Case Analyses. Further increased chances for higher-tier cases.

Players start out with 4 case analysis slots, which can range from Level S to Level C, and take 4-6 hours to complete. The level determines how the quality and quantity of items given. Players can refresh one of the case analyses at a time, for a total of up to three refreshes per day. The level will remain the same, but the item drop may change. Purchasing the Monthly Pass will unlock an additional case analysis slot.

Case Level	Research Materials	Other Items (1x skill up item or 2x Impressions)	Requirements	Time
S	60	Pass Key Stud Earring Ceramic Tea Cup Gilded Poker Cards Model Handgun Senior Attorney's Badge Smart Glasses Poetry Collection	Level 40+ cards	6 hrs
A	30	Impression III Bluetooth Earpiece Touch Stylus Pocket Watch Voice Recorder Sapphire Cufflinks Tie Clip Pill Organizer Multipurpose Military Knife	Level 25+ cards	4 hrs
B	20	Impression II Block Component Oil-Painting Tools Wooden Gardening Spade Vinyl Record Tablet Fountain Pen Bag of Dried Figs Wide-Angle Lens	Level 10+ cards	4 hrs
C	10	Impression I	Level 1+ cards	4 hrs

Additionally, players must assign Cards for each analysis. The higher level and rarity of the cards, the higher the chance of performing a Deep Analysis. A successful Deep Analysis grants 3x the rewards for that case analysis.

Study Room

Unlocked after Main Story Episode 4-15. Research Materials gained from the File Room can be used to increase Confidence Level (CL). A player's Study Room has an initial cap of 20 CL, which can be increased as Headquarters Level increases.

HQ Level	Study Room	CL Cap
1	I	20
4	II	30
8	III	40
12	IV	50
14	V	60
16	VI	70
17	VII	80
19	VIII	90
20	IX	100

Confidence Level

In-game explanation of the Study Room. Click to expand.

Leveling up Confidence Level requires Research Materials from the File Room. Every level grants a Confidence Point (CP) and increases the player's base HP Level.

CL	Research Materials to Next Level	HP
1	0	100
2	40	200
3	80	300
4	120	400
5	160	500
6	240	600
7	280	700
8	320	800
9	360	900
10	400	1000
11	460	1200
12	520	1400
13	580	1600
14	640	1800
15	720	2000
16	800	2200
17	880	2400
18	960	2600
19	1040	2800
20	1160	3000
21	1280	3300
22	1400
...

The required exp to the next level is [math]\displaystyle{ ( }[/math]previous level's required EXP[math]\displaystyle{ ) + ceiling((CL + 1)/10)*40 }[/math]. The HP gained is [math]\displaystyle{ ( }[/math]previous level's HP[math]\displaystyle{ ) + ceiling(CL/10)*100 }[/math].

For example, at level 21, it is [math]\displaystyle{ 1160 + ceiling(22/10)*40 = 1160 + 3*40 = 1280 }[/math] EXP needed to the next level, and [math]\displaystyle{ 3000 + ceiling(21/10)*100 = 3000 + 3*100 = 3300 }[/math] HP.

Talents

Confidence Points can be used to learn Talents. Leveling up a talent costs 1 CP. Talents are buffs that are helpful during debates, for example boosting a player's Influence (Attack) and Defense.

Talents are arranged in a skill tree and have a minimum CL Lv. required to unlock. Some talents also require a previous entry in the skill tree to be raised before the talent can be raised.

Logical Thinking Talents

Logical Thinking refers to the thought bubble that appears over the MC's head during debates. This bubble starts filled up at 50%. Without talents, this bubble fills back up to 50% each time a player uses a card.

If a player has a talent that reduces the time of the next logical thinking, then the bubble will fill up by the talent's given %. Once the bubble is filled to 100%, a player will be able to take two turns in a row without the enemy counterattacking in between.

For the talent skills, the following are the trigger effects:

• Reorganizing cards refers to refreshing your deck.
• Refuting an argument refers to destroying an argument.
• Trumping an argument refers to attacking an argument with the attribute with increased effectiveness against it (e.g. using a logic argument on an empathy argument).

Recommended Talent Order

It is generally recommended to prioritize offensive skills first. This is because due to the limited turn mechanics during debates, it is recommended to hit the enemy as hard as possible rather than try to defensively turtle a fight. Defense skills may still be warranted though if a player finds themselves getting killed by the enemy.

After offensive skills, the talent skill choices are more flexible and may vary player to player depending on preference.

Order	Talent	Explanation
1	Boost the Influence of <Attribute> cards	Prioritize offensive skills first.
2	Boost damage dealt to <Attribute> cards	Prioritize offensive skills first.
3	Reduce the time of your next logical thinking after refuting an argument.	Reducing the time of your next logical thinking allows you to attack twice, meaning you take less damage from the enemy. On a lesser note, the talent can also slightly speed up Auto runs by reducing enemy turn animation time. The main draw is the next talent this unlocks.
4	After refuting an argument, recover HP equal to 1/2/3% of damage dealt.	Allows the player to heal after refuting an argument. Another defensive skill helpful if a player needs to heal up HP during close fights. For stronger enemies, this can gain you extra turns where you otherwise would've been defeated.
5	Boost Defense of <Attribute> cards Reduce damage taken from <Attribute> arguments	The order these can be leveled is flexible. Unlike the other logical thinking skills which may only happen a few times during a fight, defense talents are a passive skill that will always take effect and don't require a trigger. When you reach CL 29 though, prioritize #6.
6	Boost damage dealt	Prioritize this skill by saving a point at CL 29 and then using both points when unlocked at CL 30.

Contribution Level

Added during the major version update on Oct 9 2023, the NXX HQ Contribution Level system rewards players for spending real money on the game; this system is in addition to the existing Total Purchases system (P-Points) in the Mall. The player's Contribution Level is equal to the player's current Total Purchases level. As the player gains Contribution Levels, greater rewards are available to claim daily and weekly.

On days a player levels up, rewards for both the old level and new level may be claimed. Note that rewards do not roll over and must be claimed before each daily (04:00 UTC+9) and weekly (Monday 04:00 UTC+9) reset to avoid missing them.
