# ▼ Introduction
# =-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=
# Absorbing elements have been taken out of RPG Maker VX Ace despite being a
# possible feature in the past RPG Maker iterations. This script brings back
# the ability to absorb elemental rates by applying them as traits for actors,
# classes, weapons, armours, enemies, and states.
# 
# If a target is inherently strong against the element absorbed, then more
# will be absorbed. If the target is inherently weak to the element absorbed,
# then less will be absorbed. The rate of which absorption takes effect is
# dependent on the target's natural affinity to the element.
