Required Plugins

The following plugins are required in order to use this plugin.

Place the following plugins above this plugin located in the Plugin Manager.

Yanfly Engine Plugins

This plugin is a part of the Yanfly Engine Plugins library.


This plugin requires YEP_ItemCore.
Make sure this plugin is located under YEP_ItemCore in the plugin list.

This plugin adds Item Upgraders, where you can select the base item and then
apply the appropriate Item Upgraders onto it to boost its parameters.



RPG Maker MV's editor is unable to allow for custom traits/properties that a game dev may wish to associate with a database object, event, map, etc. Notetags are used to work around such limitations by allowing the game dev to tag certain traits/properties using specific Notetags declared by the related plugin.

Here is a list of Notetag(s) that you may use.


The following notetags can be used to modify item upgrades.

Weapon, and Armor Notetags
  <Upgrade Slots: x>
  This sets the number of times an item can be upgraded instead of the
  default amount defined in the database.

  <Slot Variance: x>
  This makes it so that there is a random variance for the number of slots
  provided through the item. If this notetag isn't used, it will go by the
  setting in the parameters.

  <Upgrade Sound: filename>
  Changes the upgrade sound played to 'filename'. If this notetag isn't
  used, the 'Default Sound' parameter sound will be used instead.

  <Upgrade Effect>
  </Upgrade Effect>
  These are the effects applied (in the order they're listed). Refer to the
  'Upgrade Effects List' in the next section to have those effects applied
  to the upgraded item.

  <Upgrade Item Type: All>
  <Upgrade Item Type: Regular>
  <Upgrade Item Type: Key>
  <Upgrade Item Type: Hidden A>
  <Upgrade Item Type: Hidden B>
  <Upgrade Item Type: Always>
  <Upgrade Item Type: Battle>
  <Upgrade Item Type: Menu>
  <Upgrade Item Type: Never>
  <Upgrade Item Type: string>
  This makes it so this item can be used to upgrade the item that matches
  either the item type or the item occassion. If none of those work for you,
  you can use the following notetag and place an instance for 'string'
  inside of the item upgrade types.

  <Type: string>
  Puts this type into the notebox for items (not weapons nor armors) and it
  will add 'string' as its type. You can insert multiple copies of this
  notetag to enable the item to have more types. Any types in here that
  match the types for the previous notetag will enable the item to be
  upgradeable by that upgrade item type.

  <Upgrade Weapon Type: x>
  <Upgrade Weapon Type: x, x, x>
  <Upgrade Weapon Type: x through x>
  This makes it so that only weapon types x can use this item for upgrade.
  If you use weapon type 0, all weapons can be upgraded using this item.

  <Upgrade Armor Type: x>
  <Upgrade Armor Type: x, x, x>
  <Upgrade Armor Type: x through x>
  This makes it so that only armor types x can use this item for upgrade.
  If you use armor type 0, all armor can be upgraded using this item.

notetag to have it apply the desired effects to the upgraded item.

  Slots: x                - Changes the slot consumption cost to x. *Note1
  Stat: +x                - Increases 'Stat' by x. *Note1
  Stat: +x%               - Increases 'Stat' by x% of base stat. *Note1

Note1: 'Stat' is to be replaced by 'MaxHP', 'MaxMP', 'ATK', 'DEF', 'MAT',
'MDF', 'AGI', 'LUK', 'SLOTS', 'ALL' or 'CURRENT'. 'ALL' affects all stats.
'CURRENT' affects only non-zero stats. This effect will also increase the
boost count (+x) by 1 and update the item's name.

Note2: This does not alter boost count nor update the item's name unless
it is altered by the effect.

Note3: Because this effect resets absolutely everything about an item, it
will send the player away from the upgrade menu to reset the standings of
the item.

Note4: This requires the Item Picture Images plugin.
