#_/ This script allows you to increase the amount of items and equipment which
#_/ are "dropped" by an enemy after it is defeated.
#_/----------------------------------------------------------------------------
#_/ Instructions For Usage
#_/ To make use of this function, you must insert the <drop> tag into the
#_/ "Notes" box in the desired enemy in the database.
#_/
#_/ The format is as such: <drop ItemType:ID Probability/Percentile>
#_/ Where ItemType = A = Armor, I = Item, W = Weapon
#_/ Where ID = The ID # of the item/equipment in the database
#_/ Where Probability = A fraction statement (IE 1/4) which determines the
#_/ chance of the item dropping
#_/ OR
#_/ Where Percentile = A percentage chance (IE 70%) of the item dropping
#_/============================================================================
#_/ Example: You have a bandit (enemy) who has a Long Sword you'd like for him
#_/ to drop at a 50% chance. Tag him with:
#_/ <drop W:2 50%>
#_/ OR
#_/ <drop W:2 1/2>
#_/ Simple, yes?
#_/============================================================================
#_/ Installation: Insert above KGC_BattleDifficulty and KGC_EnemyGuide.
