Drop Rate Equation:
| From: | To: |
The item drop rate equation calculates the probability of obtaining at least one drop after multiple attempts in Elden Ring. It provides a mathematical way to understand your chances of getting rare items after a certain number of tries.
The calculator uses the drop rate equation:
Where:
Explanation: The equation calculates the probability of getting at least one successful drop after k attempts, considering the independent probability p for each attempt.
Details: Understanding drop probabilities helps players plan their farming strategies, estimate time investment for rare items, and make informed decisions about item acquisition in Elden Ring.
Tips: Enter the drop probability per attempt (typically between 0.001-0.5 for most items) and the number of attempts you plan to make. Both values must be positive numbers with p between 0 and 1.
Q1: How accurate is this calculation for Elden Ring?
A: This calculation provides the theoretical probability based on independent attempts. Actual results may vary due to game mechanics and random number generation.
Q2: What are typical drop rates in Elden Ring?
A: Drop rates vary significantly by item, ranging from very rare (0.5-2%) to more common (10-30%). Some unique items may have even lower drop rates.
Q3: Does increasing discovery stat affect the calculation?
A: Yes, the discovery stat increases the base drop probability p. You should use the adjusted probability after accounting for your discovery stat.
Q4: Are drop attempts truly independent?
A: In most games including Elden Ring, each drop attempt is treated as an independent event with the same probability, making this calculation valid.
Q5: How many attempts are needed for a high probability?
A: For a 99% chance of getting an item with 1% drop rate, you'd need approximately 459 attempts. The calculator helps determine this for any probability.
