Drop Rate Formula:
| From: | To: |
The drop rate formula calculates the probability of obtaining at least one successful drop after multiple attempts in Dark Souls 3. It provides a mathematical approach to understanding item acquisition probabilities based on base drop rates and number of attempts.
The calculator uses the drop rate formula:
Where:
Explanation: The formula calculates the complementary probability of not getting the drop in all attempts, then subtracts from 1 to get the probability of getting at least one drop.
Details: Understanding drop probabilities helps players optimize farming strategies, estimate time investment for rare items, and make informed decisions about item discovery gear and consumables.
Tips: Enter base drop probability (between 0 and 1) and number of attempts (positive integer). All values must be valid (0 ≤ p ≤ 1, k ≥ 1).
Q1: How accurate are the base drop rates in Dark Souls 3?
A: Base drop rates vary by item and are typically low for rare items (often 1-5%). Community testing has established approximate rates for most items.
Q2: Does item discovery affect the calculation?
A: Yes, item discovery increases the base drop probability. The formula uses the adjusted probability after item discovery bonuses.
Q3: What's a good number of attempts for rare items?
A: For items with 1% drop rate, about 300 attempts gives ~95% chance. For 5% rate, about 60 attempts gives similar probability.
Q4: Are drop rates independent between attempts?
A: Yes, the formula assumes each attempt is independent with constant probability, which is generally true for Dark Souls 3 drops.
Q5: Can this calculator predict exact drop counts?
A: No, it calculates probability of at least one drop. For expected number of drops, use p × k instead.
