+//===== rAthena Documentation ================================
+//= Mob Item Ratio Database Structure
+//===== By: ==================================================
+//= rAthena Dev Team
+//===== Last Updated: ========================================
+//= 20210624
+//===== Description: =========================================
+//= Explanation of the mob_item_ratio.yml file and structure.
+//============================================================
+
+Item base drop rates defined in mob_db.yml will not get multiplied by global item_rate* values (aka drop rates) from
+conf/battle/drops.conf and instead, Ratio will be used (100 = 1x).
+If no Mob is specified, all monsters will be affected, otherwise only the ones listed.
+
+Examples:
+Jellopies from monsters will drop with 1x drop rate regardless of global drop rate
+Body:
+ - Item: Jellopy
+   Ratio: 100
+
+Jellopies from monsters will drop with 10x drop rate regardless of global drop rate
+Body:
+ - Item: Jellopy
+   Ratio: 1000
+
+Removes Jellopies from monsters drop
+Body:
+ - Item: Jellopy
+   Ratio: 0
+
+Jellopies from Porings will drop with 1x drop rate. Other monsters that drop Jellopies are unaffected (use global drop rate).
+Body:
+ - Item: Jellopy
+   Ratio: 100
+   List:
+     PORING: true
+
+Notes:
+- Does not override item_drop_*_min/max settings.
+- Does not affect card/item-granted drops. To adjust card/item-granted drops, edit them in item_db.
+- Does affect MVP prizes and Treasure Boxes.
+- You can add only ONE Ratio per Item. If you need various ratios for different monsters, override drop rate with Ratio=100 and edit base drop rates in mob_db.
+- This file is reloaded by @reloadmobdb.
