About this tool

Biologist quests are vital for Metin2 character growth, granting permanent stat bonuses. They are crucial for endgame and PvP. However, these quests involve daily item turn-ins with a chance of failure. This can be frustrating and time-consuming, making planning essential.

This calculator removes the guesswork. Input your required successful turn-ins and success probability. The tool estimates total attempts needed. This helps you farm the right items, manage completion time, and decide on using Biologist Elixirs or other buffs. Plan smarter, play better.

How to use it

  1. 01

    Access the Calculator

    Go to the Metin2 Bio Quest Calculator page. The interface is simple, letting you quickly enter details and get an estimate.

  2. 02

    Enter Required Turn-ins

    In the 'Required Successful Turn-ins' field, enter the exact number of items the Biologist needs. For example, for 'Orc Teeth' needing 20 successes, type '20'. This is your quest's main goal.

  3. 03

    Set Your Success Probability

    Find the 'Success Probability' field. Enter your chance of successfully turning in an item, usually a percentage like 70% or 80%. Enter it as a decimal (e.g., 70% is '0.70'). This value is key for accuracy.

  4. 04

    View Expected Attempts

    After entering both values, the calculator instantly shows 'Expected Attempts'. This is the total number of times you'll likely try turning in items to get the required successes. It factors in failures based on your probability.

  5. 05

    Evaluate Buffs and Elixirs

    Try different success probabilities. Increase the value (e.g., from 0.70 to 0.80, or 1.00 with an Elixir) to see how buffs affect attempts. This helps you decide if an Elixir's cost is worth the time and item savings.

  6. 06

    Plan Your Farming and Time

    Use the 'Expected Attempts' to estimate how many quest items to farm. It also shows how many real-world days the quest might take, given the one-turn-in-per-day limit. This helps with resource management and planning.

WORKED EXAMPLE

Calculating Attempts for Orc Tooth Quest

The calculator shows 'Expected Attempts': 28.57.

You're doing Biologist Chaegirab's Orc Tooth quest, needing 20 successful turn-ins. Your success chance is 70%. You want to know how many Orc Teeth to farm and how long it will take.

Required Successful Turn-ins20 (user-entered example)Success Probability0.70 (70%) (user-entered example)
FormulaExpected Attempts = Required Successful Turn-ins / Success Probability
  1. Identify the 'Required Successful Turn-ins': 20.
  2. Identify your 'Success Probability': 0.70 (which is 70%).
  3. Divide the required successful turn-ins by the success probability: 20 / 0.70.
  4. Calculate the result: 28.57.
Success ProbabilityExpected AttemptsInterpretation
50% (0.50)40This quest would likely take 40 days and 40 items.
70% (0.70)29This quest would likely take 29 days and 29 items.
80% (0.80)25This quest would likely take 25 days and 25 items.
100% (1.00) with Elixir20This quest would take exactly 20 days and 20 items. This is the fastest option.
Original interpretation

The calculator shows 'Expected Attempts': 28.57. This means you'll likely need about 29 attempts to finish the quest. With one turn-in per day, it will probably take 29 days. Aim to farm 29-30 Orc Teeth to be safe. This helps manage your farming and avoids running out of items.

Limitations

  • This tool only estimates attempts for successful turn-ins. It doesn't factor in item drop rates or availability; you still need to farm items.
  • The calculator assumes a constant success probability. If your success chance changes (e.g., buffs expire), the accuracy may decrease.
  • Economic factors like Elixir costs or farming opportunity costs are not included. Players must consider these independently.
  • The result is an 'expected' average. Your actual attempts might be higher or lower due to randomness. It's a guide, not a guarantee.
  • The calculation doesn't account for missing daily turn-ins or other in-game commitments.
  • This tool doesn't list specific quest item names or locations. Users should know their current quest items.
