Add drops on monsters only on specifics maps

🌍 Overview

The mobitemdrop mapflag is a custom feature developed for the rAthena emulator.
It enables customized item drops for specific monsters on specific maps, giving administrators and event managers powerful control over in-game loot without modifying global mob databases.

🧩 Key Features

• Map-Specific Custom Drops: Define drop tables per map, per mob, without affecting other areas or the global configuration.

• Fine-Grained Control: Customize multiple item IDs and their drop rates for each monster.

• Drop caps and bonuses (e.g. SC_ITEMBOOST) are properly respected.

• Instance Support: Fully compatible with rAthena’s instance system—mob drop customizations are properly cloned into instance maps.

• Script-Based Configuration: Easily define drop settings via a dedicated script file (npc/mapflag/mobitemdrop.txt).

📜 Usage Example

This configuration will make monster ID 1002 on gef_fild09 drop items 514 and 515 with a 100% rate (10000 ‰ = 100%).
