Choose C0 if the account still needs roster coverage or future-banner flexibility. Consider C1 only when the first duplicate has a clear gameplay reason and the route is short enough to protect the next target. Treat C2 as a pre-planned spend cap, not a bonus after C1, because every extra constellation can behave like another limited-character chase.
This guide does not rank specific Genshin characters. Constellation value changes by kit, account, and play style. The safer question is budget-first: can the account afford another featured-copy route after pity, guarantee, saved Fates, saved Primogems, banner time, and future banners are counted?

C0 C1 C2 constellation budget matrix for Genshin Impact showing stop, continue, and save decisions so the route stays tied to measured resources instead of impulse spending.
Treat C0, C1, and C2 as Separate Targets
C0 is the clean target: obtain the limited character once. C1 means obtaining one duplicate for the first constellation level. C2 means obtaining two duplicates after the first copy.
Public Genshin constellation references describe non-Traveler constellation levels as being unlocked with a character-specific Stella Fortuna, and players obtain that character's Stella Fortuna when obtaining a duplicate through routes such as Wishes, Paimon's Bargains, or Events. The Traveler is a special case, so do not use Traveler constellation logic for limited banner spending.
That means C1 is not a small upgrade button. It is another copy target. C2 is another copy target after that.
| Target | What it means | Budget question |
|---|---|---|
| C0 | First copy of the character | Is the character worth this banner's saved pulls? |
| C1 | One duplicate after C0 | Is the first duplicate worth risking the next goal? |
| C2 | Two duplicates after C0 | Is the account comfortable committing to a deeper route? |
| Stop after C0 | Save remaining resources | Is future flexibility more valuable than the constellation? |
For most accounts, C0 is the default target until a specific constellation changes the actual play pattern. Liking the character can be enough reason to pull C0 if the budget supports it. It is not automatically enough reason to chase C1 or C2, because duplicates compete with new characters, weapons, reruns, and emergency savings.
Use Ceilings to See the Risk
The public Character Event Wish reference describes a 5-star character ceiling at the 90th wish and a promotional 5-star character route that can require up to 180 wishes if the first 5-star is not the featured character. The public Primogem reference lists Intertwined Fate as costing 160 Primogems.
From zero pity with no guarantee, a cautious ceiling looks like this:
| Target depth | Featured copies needed | Pull ceiling from a clean start | Primogem ceiling before savings |
|---|---|---|---|
| C0 | 1 | Up to 180 pulls | 28,800 |
| C1 | 2 | Up to 360 pulls | 57,600 |
| C2 | 3 | Up to 540 pulls | 86,400 |
These are not recommendations. They are stress-test numbers. Many real accounts need less because pity, guarantee, saved Fates, saved Primogems, early 5-star pulls, and banner income reduce the actual gap.
The table is useful because it shows why C1 and C2 decisions should happen before checkout, not after the first copy arrives.
Recalculate From Your Current Pity and Guarantee
The clean-start ceiling is useful for risk awareness, but it is not the number most players should use at checkout. The practical budget starts from the account's current pity, guarantee status, and saved resources.
Use this sequence:
- Count current pity on the Character Event Wish.
- Mark whether the next 5-star is guaranteed to be the promotional character.
- Convert saved Intertwined Fates directly to pulls.
- Convert saved Primogems at 160 Primogems per pull.
- Subtract those resources from the remaining target route.
- Recheck after every 5-star before continuing toward C1 or C2.
| Current state | C0 planning meaning | C1/C2 caution |
|---|---|---|
| 0 pity, no guarantee | Budget against the full 180-pull featured-copy ceiling | Do not assume C1 is close after C0 |
| High pity, no guarantee | The first 5-star may arrive sooner, but can still miss featured | Keep enough resources for the second 5-star route |
| Guaranteed featured | C0 route is much shorter than a clean-start 180 ceiling | Spending the guarantee on C1 removes it from the next banner |
| C0 already obtained | New pity and guarantee state decide the next duplicate route | C1 is a new target, not leftover momentum |
| Lost 50/50 after C0 | Next featured copy is protected if the banner rules apply | Decide whether that guarantee belongs to C1 or a future character |
C0 Is Usually the Budget Anchor
C0 is the safest default because it unlocks the character while preserving the most future flexibility. It is usually the right anchor when the account wants more roster coverage, the next banner is important, or the current character is strong enough at base copy for the player's goals.
Choose C0 as the main target when:
- The account is missing a role or element more than it needs a duplicate.
- A future banner is already a priority.
- The character works for the intended content at base copy.
- The player would regret using the next banner's Primogems today.
C0 also makes top-up decisions cleaner. Once the first copy is secured, the player can stop, review the account, and decide whether the remaining resources should stay untouched.
| If your account looks like this | C0 is usually the cleaner route |
|---|---|
| You need a missing element, role, or team option | A new unit adds more account coverage than a duplicate |
| You have one must-pull rerun soon | C0 protects that future budget |
| The character's base kit already solves your use case | Extra constellations become comfort, not need |
| Your top-up gap is large before C0 | Do not expand the target to C1 until C0 is actually secured |
C1 Needs a Clear Reason
C1 can be reasonable when the first duplicate meaningfully changes the way a character feels, fixes an energy or uptime issue, or improves a favorite unit enough that future banners are less important.
The warning is simple: C1 starts a new featured-copy chase. If the account is not guaranteed, the next 5-star might not be the promotional character. If the account is guaranteed, using that guarantee on C1 also means it is no longer saved for a future character.
Use this C1 check:
| Question | Continue toward C1 if... | Stop at C0 if... |
|---|---|---|
| Future banner pressure | No near-term target matters more | The next banner already has a slot in the budget |
| Pity and guarantee | The path is short or protected | The route could reopen a full 50/50 cycle |
| Account value | The duplicate changes actual use | It is only a collection impulse |
| Saved resources | The gap is covered without strain | A direct top-up would be needed for a marginal gain |
If the C1 reason cannot be explained without hype, stop at C0 and revisit after testing the character.
Good C1 reasons are specific: smoother rotation, better uptime, easier energy management, a key quality-of-life change, or a favorite character that will stay on the account for a long time. Weak C1 reasons sound like pressure: already being close, hearing that C1 is good, or feeling that a top-up means the banner should continue.
C2 Is a Commitment, Not a Bonus
C2 should be treated as a deliberate account investment. Some characters have famous early constellations, but a general budget guide should not assume that every C2 is worth chasing.
The practical issue is opportunity cost. A C2 route can consume enough pulls to cover multiple future C0 characters, or a C0 plus weapon plan, depending on luck and current pity. That does not make C2 wrong. It means C2 should compete against those alternatives in the budget.
Before planning C2, ask:
- Is C0 already secured or fully budgeted?
- Is C1 already valuable on its own?
- Would C2 still feel worth it if the next 5-star misses?
- Are future characters, weapons, and reruns already protected?
- Is the spending limit set before opening the banner?
If any answer is unclear, C2 is probably a wait-and-recalculate target.
| C2 trigger | Better action |
|---|---|
| C2 is famous but you have not tested C0 | Stop, play C0 first, then recalculate |
| C1 is weak but C2 is strong | Treat the route as a full C2 commitment, not a small extension |
| A future character is already planned | Reserve that banner budget before counting any C2 gap |
| You need a signature weapon too | Compare C2 against weapon and future-character routes before spending |
| The remaining gap requires a large top-up | Set a hard cap before opening the banner again |
Where Top-Up Fits in a Constellation Plan
A top-up should close a measured gap, not create a bigger target. After C0, it is easy to think "only one more copy" and ignore that the next copy still follows banner rules.
Recalculate after every 5-star:
- Check whether the promotional character was obtained.
- Record the new pity and guarantee state.
- Count remaining Intertwined Fates and Primogems.
- Decide whether the next copy still beats future banners.
- Only then calculate any Genesis Crystal gap.
Here is the simple gap formula:
| Step | Formula or check |
|---|---|
| Pulls still needed | Target route ceiling minus current pity and guaranteed-route reduction |
| Saved pull value | Intertwined Fates plus Primogems divided by 160 |
| Remaining pull gap | Pulls still needed minus saved pull value |
| Primogem gap | Remaining pull gap multiplied by 160 |
| Genesis Crystal check | Only after the Primogem gap is known and the target is fixed |
If a measured shortfall remains, the Genshin Impact top-up page is the U7BUY page to review for Genshin-specific UID, server, and Genesis Crystal package details. The page states that Genesis Crystals can convert to Primogems at a 1:1 ratio, but the purchase decision should still come after the constellation target is fixed.
Checkout Checks for Duplicate Chasing
U7BUY's Genshin page lists supported regions such as America, Europe, Asia, and TW/HK/MO, and it asks for the Genshin UID and server region as delivery information. That matters more when chasing duplicates because players may place several orders close together.
Before any checkout, verify:
- The UID is copied from the in-game profile.
- The selected server matches the account.
- The package is based on the current post-pull gap.
- First-top-up bonus is counted only if the account confirms eligibility.
- Order instructions, delivery terms, and refund handling are reviewed.
- Third-party top-up services may involve account, delivery, or regional restrictions.
Do not let repeated pulls make the checkout process casual. A wrong UID or server can turn a clear budget plan into a support problem.
A Practical Stop Rule
The cleanest constellation plan is written before pulling:
| Budget profile | Stop rule | Why it works |
|---|---|---|
| Low spend / future-focused | Stop at C0 | Keeps the next banner alive |
| Favorite character, limited buffer | Try C1 only if the path stays short | Avoids turning a win into a large chase |
| Saved for months | Budget C0 first, then reassess C1 | Prevents C2 pressure from absorbing all savings |
| Deep constellation plan | Pre-set C2 cap and stop on limit | Avoids reacting emotionally after each 5-star |
| Unsure after losing a 50/50 | Save the guarantee unless C1/C2 was already planned | Protects a future character from impulse spending |
This stop rule is not about being timid. It is about keeping the banner from making the decision for you.
Keep Future Banners in the Same Budget
C1 and C2 are easiest to justify when they do not steal from a future plan. If a future character is already a must-pull, that future banner belongs in today's calculation.
For broader planning, the Genshin Impact guide hub can help you check recent banner and guide coverage before deciding whether a duplicate is worth more than keeping Primogems for later.
The best constellation choice is the one that still looks sensible after the current banner excitement fades. For many accounts, that is C0. For some favorite-character accounts, it is C1. C2 should be reserved for players who have already accepted the opportunity cost.
Before you turn the plan into a purchase, run the same four-step gap check one more time: count the resources already on the account, convert the remaining pulls into Primogems, choose the lowest-risk route, and verify the checkout details.

FAQs
What Is C0 in Genshin Impact?
C0 means the character has been obtained once and has no duplicate constellation levels unlocked. It is the baseline target for most limited character pull budgets.
What Is C1 in Genshin Impact?
C1 means the first constellation level after the base copy. For non-Traveler characters, this normally requires obtaining a duplicate and using that character's Stella Fortuna.
What Is C2 in Genshin Impact?
C2 means two constellation levels after the base copy. In budget terms, it usually means chasing the character three total times: once for C0, once for C1, and once for C2.
Is C1 Always Better Than a New C0 Character?
No. C1 may improve a favorite character, but a new C0 character can add a role, element, team option, or future flexibility. Compare the duplicate against the next banner before spending.
How Many Primogems Can C0 to C2 Require?
From zero pity with no guarantee, a cautious full-ceiling C0-to-C2 plan can be up to three featured-copy routes. At 160 Primogems per pull and up to 180 pulls per featured copy route, that stress-test ceiling is 86,400 Primogems before savings and early pulls reduce the need.
Should C2 Be Planned Before Buying Genesis Crystals?
Yes. Set the C2 cap before considering Genesis Crystals. If the target changes after each 5-star, it becomes easy to spend for momentum rather than a planned account goal.
How Should Players Recalculate After Getting a 5-Star?
Record whether the 5-star was the promotional character, update pity and guarantee status, count remaining Intertwined Fates and Primogems, then decide whether the next copy still beats future banners. Do this before any new top-up decision.
