# 2013.03.16 - Additional skill element
# 2012.01.06 - Minor update for compatability with any absorption script
# 2012.01.05 - Finished Script
# 2012.01.04 - Started Script
#
#==============================================================================
# ▼ Introduction
# =-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=
# The RM* series has always had a particularly awful method of determining
# damage done when multiple elements are applied - all it does is take the best
# rate and apply it, even if the other elements are nullified!
#
# With this script, elemental damage will be merged proportionally, so that
# using a Soldier's hypothetical attack skills will also use that Soldier's
# inherent elements (from, say, his Fire Spear or an Infuse Ice status effect)
# and apply them ALL against a foe. If a foe is weak to both Piercing and Fire,
# they'll take even more damage than by default - but they'll take blended damage
# if they take double Piercing and half Fire damage.
#
# If you don't get it, know this: just plugging this script in will make
# your elemental equipment much more useful.
#
#==============================================================================
# ▼ Instructions
# =-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=
# To install this script, open up your script editor and copy/paste this script
# to an open slot below ▼ Materials/素材 but above ▼ Main. Remember to save.
#
# Edit the settings in the module below as you see fit.
#
# For those who wish to add more skill elements, just type this in skill note
# <elements id: x> or
# <elements id: x, x>
#==============================================================================
# ▼ Compatibility
# =-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=
# This script is made strictly for RPG Maker VX Ace. It is highly unlikely that
# it will run with RPG Maker VX without adjusting.
#
# This script works with YEA Battle Engine Add-On: Elemental Popups without
# any adjustment on either end. The most damaging element's color will be used.
# There are also no issues with YEA Element Absorb.
#
# Overwritten methods:
#   Game_Battler
#      item_element_rate

    # Pick the type of elemental merging or blending you wish for your game
    # to use. This will take all potential elements and, instead of using the
    # default mechanic of picking only the best rate, will merge the rates.
    # Ignore this section if you want this happen, but don't dare touch
    # the math.
    #=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-
    # 0: Default RMAce. Will find the best rate out of all potential elements
    # 1: Addititive. If results are 100%, 150%, and 80%, the total will be 130%
    #      Ex.  100 + (100 - 100) + (150 - 100) + (80 - 100) = 130%
    #      Ex.  100 + (0 - 100) + (150 - 100) = 50%
    # 2: Multiplicative. If results are 100%, 150%, and 80%,
    #      the total will be 120%
    #      Ex.  100 * (100 / 100) * (150 / 100) * (80 / 100) = 120%
    #      Ex.  100 * (0 / 100) * (150 / 100) = 0%
    # 3: Multiplicative Psuedo-Null. If results are 100%, 150%, and 80%,
    #      the total will be 120%. Nulled (fully resisted) elements are
    #      used to divide overall damage done by 10 (RECOMMENDED)
    #      Ex.  100 * (100 / 100) * (150 / 100) * (80 / 100) = 120%
    #      Ex.  100 * ([0 + 10] / 100) * (150 / 100) = 15% (Default)
    MERGE_TYPE = 3

    # If you use MERGE_TYPE 3, nulled elements will divide overall damage done
    # by this amount. Default is 10, but examples for other amounts are given
    # below. Note that attacks with a single element, which is nulled, will
    # deal 0 damage.
    #      Ex.  150% / [10] = 15% (Default)
    #      Ex.  150% / [20] = 7.5%
    #      Ex.  150% / [5] = 30%
    #      Ex.  150% / [3] = 50%
    PSUEDO_NULL_AMT = 10

    # This applies to all elemental merge types. When the final rate of damage
    # is determined, it is checked against this percentage. If below this
    # constant, the damage becomes 0. A value from 10-20 is recommended.
    #      Ex.  100% *  10% = [10% is <= 10%] = 0% (Default)
    # If you do not wish to use this feature, set this constant to 0.
