1. What is the ToA Drop Rate Formula?

The ToA (Tombs of Amascut) drop rate formula calculates the cumulative probability of obtaining a drop after multiple attempts in Old School RuneScape. It provides a mathematical way to determine your chances of receiving a specific item after a certain number of raid completions.

2. How Does the Calculator Work?

The calculator uses the drop rate formula:

Where:

• \( p \) — Drop probability per attempt (dimensionless)
• \( k \) — Number of attempts (dimensionless)
• \( P \) — Cumulative drop probability (dimensionless)

Explanation: The formula calculates the probability of getting at least one drop after k attempts, considering the independent probability p for each attempt.

3. Importance of Drop Rate Calculation

Details: Understanding drop probabilities helps players set realistic expectations, plan their gameplay time, and make informed decisions about pursuing specific items in the Tombs of Amascut raid.

4. Using the Calculator

Tips: Enter the drop probability per attempt (typically a small decimal value) and the number of attempts you plan to make. Both values must be positive numbers.

5. Frequently Asked Questions (FAQ)

Q1: What is a typical drop probability in ToA?
A: Drop probabilities vary by item and raid level, but typically range from 1/20 to 1/1000 for rare items.

Q2: Does this formula account for dry streaks?
A: Yes, the formula shows the probability of getting at least one drop, which increases with more attempts but never reaches 100%.

Q3: Are drop chances independent in OSRS?
A: Yes, most drop mechanics in Old School RuneScape use independent probabilities for each attempt.

Q4: How accurate is this calculation for actual gameplay?
A: This provides the mathematical probability, but actual results may vary due to RNG (random number generation).

Q5: Can I use this for other OSRS content?
A: Yes, this formula works for any content with independent drop chances, not just Tombs of Amascut.
