Çözüldü Why My Server Drops Too Many Items Despite Low Drop Rates

The Problem

Even though I set:

• Very low DropRatio values (like 3.33E-06)
• Server.cfg DropRate = 0.5

The server still drops:
300+ items in 3 days

So what's going on?

How the Drop System Actually Works

There are two layers of drop calculations:

1) Monster Drop Table

• Controls if a group can drop
• Example:

2) Item Group Table

• Controls which item drops inside the group
• Example:

Why You Still Get Too Many Drops

1) Multiple Rolls Per Kill
The server does NOT roll once.
It rolls many times per monster kill.

Example:

• 10–50 roll attempts per kill
• Multiple item groups checked each time

→ This increases total drop chance massively.

---

2) High Monster Kill Count
Even very small chances become big over time.

Example:

• 10,000 mobs killed per day
• Tiny chance × huge number = many drops

3) Server.cfg Is a Multiplier


This does NOT mean 0.5%.

It means:

So:

Still small—but applied many times.

4) Group + Item Chance Combined

Real formula:

Even if each value is small:
→ Combined result becomes noticeable.

5) SelectRatio Is Not That Low

• 0.001 = 0.1% (actually medium in multi-roll systems)
• 0.01 = 1% (HIGH for rare items)

If you have many items in a group:
→ Drop frequency increases a lot.

How to Fix It

✔ Option 1: Lower SelectRatio

✔ Option 2: Reduce Roll Attempts
Check configs like:

• DropItemCount
• MaxDropRoll
• MonsterDropCount

✔ Option 3: Lower DropRatio

✔ Option 4: Reduce Drop Groups
Instead of:
- Weapon + Set + Accessory all dropping

Try:
- Limit to 1 group per monster

Final Conclusion

Your drop rates are not "wrong".

The system multiplies probability by:

• Number of rolls
• Number of groups
• Number of kills

Result:
Low rates × many attempts = High total drops

If needed, I can calculate your real drop rate.
Just tell me:

• Rolls per kill
• Average mobs killed per day
