# Yanfly Engine RD - Custom Element Affinity
# Last Date Updated: 2009.06.26
# Level: Normal, Hard, Lunatic
#
# Element rates were used universally for nearly everything. This goes for
# items, weapons, armours, and skills. However, the lack of control we have
# over them as far as RPG Maker VX is concerned leaves me rather disappointed.
# Keep in mind that this script is heavily geared towards element control and
# has tags split around for weapons, armours, states, and enemies.
#
#===============================================================================
# Updates:
# ----------------------------------------------------------------------------
# o 2009.04.27 - Bugfix for melee actors.
# o 2009.04.23 - Compatibility Update and bugfix.
# o 2009.04.19 - Started script and publicized.
#===============================================================================
# How to Use: Normal Mode
#===============================================================================
#
# Element control is split between multiple instances. First, we'll handle any
# elemental rank changes. These affect the battlers on the receiving end of
# an elemental attack, skill, or item.
#
# <element rank add x:y>, <element rank sub x:y>
# x is the ID of the element you wish to affect. y is the rank change.
# Insert these into weapons, equips, or states to increase or decrease an
# element rate. Note that adding an element rank means they become more
# resistant while lowering an element rate means they become weaker. Element
# rates will fluctuate amongst [Z,A,B,C,D,E,F] ranks.
#
# <element rank set x:y>
# x is the ID of the element you wish to affect. y is either [Z,A,B,C,D,E,F].
# This will set the element of battler to exactly that. There is a rule set of
# priorities. They'll be determined by the highest rank state, then weapons, and
# finally armours from top to bottom. With that said, you can place these into
# weapons, equips, and states.
#
# Elemental control for normal attacks can be applied via states, weapons, and
# equips for actors and states and enemy data for enemies.
#
# <element attack add x>
# x is the ID of the element you wish to infuse normal attacks with. If it's
# placed in a state, weapon, or equip, that battler's normal attacks will have
# that elemental attribute. If it's in an enemy notebox, that enemy will have
# normal attacks with that elemental attribute. This allows for enemies like
# elemental djinns to innately have an elemental attack or swordsmen to have a
# slashing element.
#
# <element attack sub x>
# x is the ID of the element you wish to prevent the battler from using in a
# normal attack. The removal tag will nullify any bonuses that would otherwise
# give an elemental trait to a normal attack. This can be placed inside a state,
# weapon, or equip. If placed in an enemy box, that enemy will never have such
# an elemental trait to its normal attack no matter what kind of status effect
# would provide for it. This is to prevent something like a fire slime suddenly
# using ice attacks.
#
#===============================================================================
# How to Use: Hard Mode
#===============================================================================
#
# Elemental control for skills can be adjusted with the following tags. Note
# that if you wish to use elemental control for skills, you REQUIRE Yanfly's
# Custom Damage Formula script.
#
# <element skill add x>
# x is the ID of the element you wish to infuse skills with. If it's placed in
# a state, weapon, or equip, the battler's skills will possess an additional
# element with them.
#
# <element skill sub x>
# x is the ID of the element you wish to prevent the battler from using in a
# skill. The removal tag will completely nullify any elemental traits that the
# skill would otherwise have. This can be placed inside a state, weapon, or
# equip to take effect.
#
# <element lock>
# Placing this inside of a skill's notebox to prevent that skill from having
# its elements alter through means of the two previously mentioned tags.

# <custom element x>
# If placed in a skill, this calls on case ID x. The returned element_set array
# will reveal to the damage multiplier what kind of elements you're applying to
# the skill or skills. Similar to the other Lunatic portions of other Yanfly
# Engine ReDux scripts, there is a "common_element" definition which will run
# for every skill regardless of a custom element tag or not.
