Drop Rate Equation:
| From: | To: |
The drop rate equation calculates the probability of obtaining at least one drop after multiple attempts in Elden Ring. It's based on the principle of complementary probability and is useful for farming rare items.
The calculator uses the drop rate equation:
Where:
Explanation: The equation calculates the probability of getting at least one successful drop by subtracting the probability of getting no drops from 1.
Details: Understanding drop probabilities helps players optimize their farming strategies, estimate time investment for rare items, and make informed decisions about item acquisition in Elden Ring.
Tips: Enter the base drop probability per attempt (0-1) and the number of attempts. Both values must be valid (0 ≤ p ≤ 1, k ≥ 1).
Q1: What does this equation calculate?
A: It calculates the probability of obtaining at least one drop after k attempts, given a base drop probability p per attempt.
Q2: How accurate is this calculation for Elden Ring?
A: This is the mathematical probability calculation that applies to any independent drop system, including Elden Ring's item drop mechanics.
Q3: Does increasing item discovery affect the calculation?
A: Yes, item discovery increases the base drop probability p. You should use the adjusted probability after accounting for your item discovery stat.
Q4: Are drop attempts independent in Elden Ring?
A: Yes, each enemy kill represents an independent attempt with the same base drop probability, assuming no changes to item discovery.
Q5: How can I use this to farm efficiently?
A: Calculate how many attempts you need for a desired probability, or estimate your chances after a certain number of attempts to decide whether to continue farming.
