Introduction
If you are a beginner looking for the complete Shop Guide, we have one for you. This page consists of everything you need to know about what to buy from shop: Union Shop, Arena shop, etc. Everything included. Which cube to buy? We'll answer you in detail. How about those Silver Mileages—what should I spend them on? No worries, we've got that covered too.
So, what are you waiting for? Let's get straight into it!
Glossary
Priorities are color-coded. These squares will be featured in the images below, determining items’ worth.
Common Shop
For most players, there is only 1 item worth buying in this shop. It's the free one on the top left. You can get 1-2 free items daily depending on your Core Infrastructure level, unlocked at higher levels, marked by the FREE sign above it.
For whales who have completely exhausted every resource acquisition method, there is also 1 item that you can consider buying at higher discounts. If the 2nd item is a Credit Box, it is usually cheaper. Despite its worse rate, it can help fulfill your upgrade needs.
Union Shop
Union Shop can be the most deceiving one to new players. Using currency obtained via Union Raids, players can buy spare bodies for Liberation units or batteries for their cubes.
You should absolutely never buy the spare bodies. These units are weak.
Always buy batteries only, following the recommended path:
Resilience to Lv. 15 — Resilience is the most broken cube in game and works for almost anyone. More likely than not, especially if you have Crown, you will stick to Resilience throughout your early journey in the game, so getting it to Lv. 11 for the double ELE breakpoints is not a bad idea..
Tempering Lv. 7/Quantum Lv. 7 — At any point during your ascent, if you've ever felt you need a helping hand in PvP, upgrade these cubes. Otherwise, skip them. Tempering has a measurable gain, whereas Quantum may not be necessary.
Bastion to Lv. 15 — Some units, especially SR-specific ones, may be suboptimal with Resilience. Get Bastion for them.
Destruction to Lv. 11-15 — Destruction has been one of the most used PvE cubes in Union Raid and sometimes Solo Raid, but it's situational. Make sure to get the double ELE breakpoints at Lv. 10–11.
You can start saving for future cubes after this, or you may be interested in these extra options:
Vigor Lv. 11-15/Pierce Lv. 11-15/Rupture Lv. 11-15 — In our experience, these cubes are more niche than the five above and are only usable by specific units. Because of that, unless you have all the above invested, don't bother about them.
Tempering Lv. 11-15 — You can also max out the gold-standard PvP cube.
Body Label Shop
The Body Label Shop is where you trade Body Labels (refund currency for obtaining duplicate R, SR, and SSR characters) for either Consoles or High-Quality Access Record.
For new players and even late-game players, especially if they're F2P, High-Quality Access Record is always the better choice.
Console is only better if you have too many units at max duplicate (C7), which is usually the case for whales. If you're buying consoles, consider purchasing ones that are discounted like shown in the blue box. Normally, ATK consoles (red) are the best, but some units like Cindy and XMaiden scale off HP, making the Defender HP ones (green) a circumstantial choice.
Arena Shop
Arena Shop demands currency obtained from participating and ranking in Rookie Arena and Special Arena. Here, you can find Code Manuals, a vital resource for upgrading skills. They get exhausted quickly, so you should always get them if you feel like you will run out soon, preferably from the random 3 on the left because they're cheaper. However, the elements change every day, so make sure to start buying from far ahead. In an emergency, you can buy the 4th one too, a selector, though it is more expensive.
Some veterans say buying the Selector itself is enough not to end in drought, so that is a valid strategy too. However, we do not know if this is applicable to beginners since the acquisition rate differs and they need to build more actively.
Additionally, you can get Furnace. Most people think it's a scam, but it mathematically boosts your gear gain by converting unused gear into random gear of another Manufacturer. Usually, we'd only convert Abnormals, gear usable by collab units, who don't come often. They are very expensive, nonetheless, and cost 50,000 per use (100 fragments of Furnace).
If you buy Furnace every day, you can’t buy all the 3 sets of Elemental Code Manuals all the time. Conversely, if you buy all the 3 sets of Elemental Code Manuals daily (which is possible), you won’t have enough for Furnace. Control your spending well!
Mileage Shop
The Mileage Shop contains a lot of goodies purchasable with Silver Mileage or Gold Mileage, obtained from pulling in Ordinary Recruit and Advanced Recruit respectively. They basically function as sparks, allowing you to obtain a free Nikke or their spare body every 200 pull(s).
For Silver Mileage:
If you are below 160 wall, save Silver Mileage solely for Breaking the Wall. For example, you can use Silver Mileage to obtain copies of release units at 2 LB. Only do that once you confirm you can Break the Wall, otherwise their dupe might spook you from random pulling, making you end up with C1 (Core 1) instead.
Once you pass the 160 Wall, save Silver Mileage for Treasure/Favorite Item units. Every season (±6 months), the roster of Treasure units available for purchase changes. Their spare bodies will be temporarily sold here for 6 months. If you own that new Treasure unit but do not have their copies, buy them from here.
For Gold Mileage:
Gold Mileage is for acquiring unobtained units, not their spare bodies, unlike Silver Mileage.
Trade 200 of them to get the rate-up unit of any banner instantly. We only recommend getting Pilgrim/Over-spec units, who have a 1% pull rate as opposed to the standard 2% rate for other Manufacturers. That said, you can use them on any banner, especially if you like them and have run out of gems.
You can also trade 200 of them to get a unit from the current Treasure season. For example, Moran is part of the current season. If you don't have Moran, you can get Moran, then spend 600 Silver Mileage for 3 spare bodies. However, due to these units’ being obtainable from Ordinary Recruit + Wishlist, we usually don't recommend this unless it's an emergency.
The current Favorite Item Season features:
The season will conclude on August 13, 2026 @ 03:00 JST.
The units inside the Green Box change randomly (not cyclic). With bad luck, a unit may not show up for weeks. Each slot contains its own pool of possible units, and a unit of a slot cannot show up in another slot. Here is the list of units:
Slot F:
Admi, 
Centi, 
Yuni, 
Snow White: Innocent Days, 
ReiSlot G:
Brid, 
Crow, 
Privaty, 
Soline, 
Rapunzel: Pure GraceSlot I:
Guillotine, 
Maiden, 
Maxwell, 
Vesti, 
Yulha
Recycling Shop
Recycling Shop uses two currencies obtained only from Co-op Events, which happen randomly and are accessible either via Event Interface or Banner on the main menu (on the top left slider).
For Broken Cores, you should always get the Gems, the resource boxes, and the standalone Credit every week. Yes, it is possible to keep buying them forever as long as you are active in Co-op, preferably Top 10%, which is possible if you privately team up with veterans in community servers (including the official one). Excess can be spent for Gift Tickets, which can increase Bond levels.
For Rusted Bones, you should always get the T9M (Tier 9 Manufacturer Equipment Selector). If you always get Top 10%, you can also always buy the Maintenance Kit Box II as well. Excess can then be spent for Good Teamwork Boxes. If you regularly get Top 100 in Co-op, you should have a lot of extras for them.
Exchange Shop
Usually, this is a scam shop. If you don't know what you are doing, better stay away from here. Basically, this shop allows you to convert Battle Data, which many veterans are swimming in, into Core Dust or Credit. The problem is that some people overdo it, and then they run out of Battle Data.
As for the High Quality Mold exchange, this is more of your decision. Mathematically, High Quality Mold gives more SSRs on average than High-Quality Access Record. However, it doesn't have guarantee/pity, so you either get it or you don't. We recommend YOLO-ing and opening the High Quality Molds.
Event Shop
Event Shop's content is mostly the same across events. You can obtain their currency by clearing Event Stages, which are incredibly easy and fast. Try to gain as maximum extra drop rate percentage as possible from events by using the "Reward Boost Nikkes". Note that it cannot exceed 100%. If you do have 100% and are clearing Event Stages daily, you should have enough currency to buy out all the Red items in the shop.
These are the things you should always buy:
Both types of Recruit Vouchers
Skill Manuals
Resource Crates
All types of Consoles
Event stage entry tickets (top left), which cost gems
Only buy them once Hard Mode unlocks, then clear the final repeatable stage.
The interface may vary depending on the event. Some have special themes. The 3-week events have Hard Mode in Story II, which unlocks after 2 weeks. The 2-week ones unlock Hard Mode in 1 week. If the correct stage is selected, it should reward 4H Core Dust.
If you like the decorative Title, which can be worn on profile and is limited, you can also buy it.
The rest of the currency can then be spent on either Core Dust or Credit, depending on what you need the most. Early-game players will find Core Dust more profitable (esp. those below Outpost Lv. 533, before the leap in Core Dust income), whereas veterans will love Credit because it gets scarce in higher syncs.
