Genshin Constellation Unlock Probability Calculator

Calculate the probability of obtaining multiple copies of a character or weapon. Perfect for C2 Raiden, C6 Wanderer, or R5 Signature weapon planning.

How It Works

The Genshin Constellation Unlock Probability Calculator is a high-level Monte Carlo simulation tool for dedicated constellation hunters and "Whale" accounts. By calculating the outcome of hundreds of wishes across multiple 50/50 scenarios, it provides a realistic percentage chance of reaching your target constellation level.

Formula Used

Uses binomial probability across multiple 50/50 trials with soft pity weightings (Simulated 100,000 Pull Sessions).

Real Calculation Examples

  • 1Targeting C2 from 0 Pity: ~240-280 wishes for 50% probability, 420 for high-confidence.
  • 2Targeting C6 from 0: ~630-750 wishes average; 1,000+ for 95% guarantee.
  • 3Targeting R1 Weapon from 0: ~130 wishes average, 210+ for absolute guarantee.

Genshin Constellation Probability Calculator: The Path to C6 Mastery

In Genshin Impact, a character's true potential is often locked behind their Constellations (C1-C6). While a C0 character is usually complete and playable, certain breakthroughs—like Raiden Shogun's defense-shredding C2 or Furina's game-breaking C6—transform the way you play. Our Genshin Constellation Probability Calculator is the ultimate tool for planners, allowing you to simulate tens of thousands of wishing sessions to find your realistic odds.

The Math of Multiple Copies

Calculating the odds for a single character (C0) is simple. Calculating for seven copies (C6) is advanced probability. This is because every copy involves a Bernoulli Trial with a varying success rate due to the 50/50 and Pity systems.

Average Wishes for Constellation Levels

While the "Hard Pity" for C6 is a staggering 1,260 wishes, the statistical reality is much lower. Most players will experience a mix of won and lost 50/50s and "Soft Pity" triggers.

Target level Total Copies Average Wishes (Median) "Safe" Wishes (90% Confidence)
C0 1 94 160
C1 2 188 310
C2 3 282 460
C4 5 470 740
C6 7 658 1,010

Why C2 is the "Gold Standard"

In modern Genshin Impact design, developers often place the most significant power spike at C2. This is far enough to encourage spending or dedicated saving, but close enough for F2P players to achieve once or twice a year.

  • Nahida C2: Enables Bloom reactions to Crit and reduces enemy DEF by 30%.
  • Raiden Shogun C2: Allows her Burst to ignore 60% of enemy DEF, a ~40% total DPS increase.
  • Kazuha C2: Provides a massive 200 EM buff to the entire team, making him a tiered support.
Our calculator helps you decide: "Do I have enough for C2, or should I save my 200 wishes for two separate C0 characters?"

Simulating the "Bad Luck" Streak

Our tool uses a Monte Carlo Simulation. This means we don't just give you a static number; we run 100,000 "virtual people" through the banners.
- 10% of people will get C2 in under 150 wishes.
- 10% of people will take over 400 wishes. By seeing the "Long Tail" of distribution, you can prepare yourself emotionally for the possibility that you might lose every single 50/50.

Weapon Refinement: R1 vs. R5

Planning for a 5-star weapon is even more volatile. Because the Epitomized Path requires up to 240 wishes per copy, an R5 (Refinement 5) weapon can cost as many wishes as a C6 character. For most players, R1 is the target, but for "speedrunners" and "whales," R5 is the ultimate goal. The probability of R5 is strictly gated by the 240-wish hard ceiling, making it the most expensive upgrade in the game.

The Starglitter Rebate Factor

One psychological advantage of going for C6 is the Starglitter Economy.

  • Once a 4-star character is C6, every dupe gives you 1 Wish back.
  • Once a 5-star character is C6, every dupe gives you 5 Wishes back.
By the time you are pulling for your 5th, 6th, and 7th copies of a character, your "Net Cost" per wish drops by nearly 20% due to the massive influx of Starglitter from the maxed-out 4-stars on the banner.

Whale Strategy: When to Stop?

Professional theorycrafters use our Constellation Probability Calculator to find the point of diminishing returns.
1. Identify the "Key Constellation" (e.g., Yelan C1, Hu Tao C1).
2. Look at the total Primogem cost vs. the DPS gain (e.g., 20,000 gems for 15% more damage).
3. Compare this to spending those Gems on a different character or a signature weapon. If the "cost per 1% damage increase" spikes too high, it's time to stop pulling.

Conclusion: Respect the Variance

Gacha is a game of chance, but it is also a game of Risk Management. The Genshin Constellation Unlock Probability Calculator provides the data you need to be a responsible traveler. Don't pull on hope—pull on probability. Use our tool to find your confidence interval and ensure that when the lights on the wishing screen turn gold, it's exactly what you were looking for.
