/*:
* @plugindesc v1.09 Allows your enemies to drop more than just three
* items as per the editor's limit.
* @author Yanfly Engine Plugins
*
* @help
* ============================================================================
* Introduction
* ============================================================================
*
* By default, RPG Maker MV limits enemies to only drop up to 3 items max and
* at very limited drop rates. This plugin allows you to add more than 3 items
* at drop. In addition to having more than 3 drops, this plugin also allows
* you to expand the enemy drops to have conditional drops, drops that will
* only appear before the player if certain conditions are met.
*
* ============================================================================
* Generic Drop - Notetags
* ============================================================================
*
* Use the following notetags to determine extra enemy drops. These drops will
* drop normally without any special conditions other than having to go through
* and pass a random number generator.
*
* Enemy Notetags:
*   <Item x: y%>
*   <Weapon x: y%>
*   <Armor x: y%>
*   Adds item, weapon, or armor ID of x to the enemy's drop pool with a y%
*   chance of dropping the item. Insert multiples of this notetag to add more
*   drop items for the enemy drop pool.
*
*   <Enemy Drops>
*    Item x: y%
*    Weapon x: y%
*    Armor x: y%
*   </Enemy Drops>
*   Alternatively, using the above notetag format will allow you to group a
*   large number of enemy drops together. Replace x with the item, weapon, or
*   armor ID to give the item a drop rate of y%.
*
*   <Drop Potion: x%>
*   <Drop Short Sword: x%>
*   <Drop Feather Cap: x%>
*   If you prefer to use names instead, you can use the above format for the
*   notetags. This will make the named item have a drop rate of x%. If you
*   have multiple items in your database with the same name, priority will be
*   given to the item with the highest ID in the order of item, weapons, then
*   armors. Insert multiple multiples of this notetag to add more drop items
*   for the enemy drop pool.
*
*   <Enemy Drops>
*    Potion: x%
*    Short Sword: x%
*    Feather Cap: x%
*   </Enemy Drops>
*   Alternatively, you can write your notetag like such to group together a
*   list of named items. This will make the named item have a drop rate of x%.
*   If you have multiple items in your database with the same name, priority
*   will be given to the item with the highest ID in the order of item,
*   weapons, then armors. Insert multiple multiples of this notetag to add
*   more drop items for the enemy drop pool.
*
* ============================================================================
* Conditional Drop - Notetags
* ============================================================================
*
* Sometimes, you want certain conditions to be met before enemies will drop a
* specific item. These conditional drops would have a 0% chance otherwise. For
* each condition met, you can increase or decrease the drop rate. Use the
* below format to create a conditional drop.
*
* Enemy Notetags:
*   <Conditional Item x Drop>
*    condition: +y%
*    condition: -y%
*   </Conditional Item x Drop>
*
*   <Conditional Weapon x Drop>
*    condition: +y%
*    condition: -y%
*   </Conditional Weapon x Drop>
*
*   <Conditional Armor x Drop>
*    condition: +y%
*    condition: -y%
*   </Conditional Armor x Drop>
*   The above notetags will create the conditions for item, weapon, or armor x
*   to drop. Insert various conditions in between the notetags to produce the
*   conditional rate increases or decreases of y% for the drop.
*
*   <Conditional Named Drop>
*    condition: +y%
*    condition: -y%
*   </Conditional Named Drop>
*   If you prefer to name your drop, use the above format. If database entries
*   have matching names, priority will be given to the item with the highest
*   ID in the order of items, weapons, then armor. Insert various conditions
*   in between the notetags to produce the conditional rate increases or
*   decreases for y% for the drop.
*
* The following are various conditions you may use:
*
* =-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-
* ALIVE MEMBERS EVAL
*- - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - -
* This checks the number of alive party members the player has when the drops
* are being calculated and made and runs it against an eval check.
*- - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - -
* Example:   Alive Members > 1: +20%
*            Alive Members === 2: +25%
*            Alive Members <= 3: -30%
* =-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-
*
* =-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-
* ALWAYS
*- - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - -
* This condition will always pass. This can be used as setting a base rate for
* the item drop.
*- - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - -
* Example:   Always: +50%
* =-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-
*
* =-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-
* item x COUNT EVAL
* weapon x COUNT EVAL
* armor x COUNT EVAL
* named item COUNT EVAL
*- - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - -
* This checks the quantity of specific items, weapons, armors, and/or named
* items you have. If you choose a named item and multiple database entries
* share the name of that named item, priority will be given to the highest ID
* in the order of items, weapons, and then armor.
*- - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - -
* Example:   Item 1 Count > 1: +20%
*            Weapon 2 Count === 2: +25%
*            Armor 3 Count <= 3: -30%
*            Potion Count >= 4: +35%
* =-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-
*
* =-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-
* DEAD MEMBERS EVAL
*- - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - -
* This checks the number of dead party members the player has when the drops
* are being calculated and made and runs it against an eval check.
*- - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - -
* Example:   Dead Members > 1: +20%
*            Dead Members === 2: +25%
*            Dead Members <= 3: -30%
* =-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-
*
* =-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-
* DEATH TURN EVAL
*- - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - -
* This will run an eval check to compare the turn number the enemy has died.
* This effect requires the Battle Engine Core.
*- - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - -
* Example:   Death Turn > 5: +10%
*            Death Turn === 5: +20%
*            Death Turn <= 4: +30%
* =-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-
*
* =-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-
* ENEMY LEVEL EVAL
*- - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - -
* This will run an eval check to compare the enemy's level. This effect
* requires the YEP Enemy Levels plugin.
*- - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - -
* Example:   Enemy Level === 10: +30%
*            Enemy Level <= 5: -20%
*            Enemy Level >= 15: +10%
* =-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-
*
* =-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-
* EVAL code
*- - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - -
* This will run an eval check for the code you've inserted. If it returns true
* then the condition is met.
*- - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - -
* Example:   Eval user.name() === 'Bat A': +30%
* =-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-
*
* =-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-
* LAST STRIKE SKILL X
* LAST STRIKE ITEM X
* LAST STRIKE named
*- - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - -
* This checks to see if the last strike on the enemy is item x, skill x, or a
* named action. If a named action is used and multiple database entries share
* the name of the action, priority will be given to the highest ID in the
* order of skills then items.
*- - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - -
* Example:   Last Strike Skill 40: +20%

* =-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-
* PARTY MEMBERS EVAL
*- - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - -
* This checks the number of party members (dead or alive) the player has when
* the drops are being calculated and made and runs it against an eval check.
*- - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - -
* Example:   Party Members > 1: +20%
*            Party Members === 2: +25%
*            Party Members <= 3: -30%
* =-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-

* =-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-
* RANDOM X%
*- - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - -
* This condition has a random x% chance to pass.
*- - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - -
* Example:   Random 20%: +40%
*            Random 30%: -60%
* =-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-

*
* ============================================================================
* Lunatic Mode - New JavaScript Functions~
* ============================================================================
*
* For those with JavaScript proficiency, you can make use of some of these
* newly added functions when you do an eval check for the enemy:
*
* enemy.deathTurn()
* This will return the turn the enemy died as an integer.
*
* enemy.killer()
* This will return the enemy's killer. If you would like to reference the
* killer's HP, it'd be enemy.killer().hp
*
* enemy.lastStruckAction()
* This will return either a skill or item that the enemy was last struck with.
*
* enemy.timesStruckSkill(skill ID)
* This will return a number value for the number of times it was struck by
* the skill referenced by the skill ID.
*
* enemy.timesStruckItem(item ID)
* This will return a number value for the number of times it was struck by
* the item referenced by the item ID.
*
* enemy.timesStruckSType(skill type ID)
* This will return a number value for the number of times it was struck by
* skills of the skill type ID.
*
* enemy.timesStruckState(state ID)
* This will return a number value for the number of times it was struck by
* the state referenced by the state ID.
*
* enemy.timesStruckElement(element ID)
* This will return a number value for the number of times it was struck by
* the element referenced by the element ID.
*
* ============================================================================
* Changelog
