#_/  This script allows you to create skills that deal a percentage of damage.
#_/ These skills can either do a percentage of damage relative to the remaining 
#_/ HP/MP, or a percentage relative to the target's maximum HP/MP.
#_/=============================================================================
#_/                  ◆ Instructions For Usage ◆
#_/  To make use of these functions, you must insert the desired tag into the
#_/   "Notes" box located in the skills section of the database. For example,
#_/   you want Double Attack to always inflict 15% of the target's maximum HP. 
#_/   You would then locate Double Attack in the skills tab of the database
#_/   and insert "<max_rate_damage Value>" (without quotations) in the note box.
#_/    Where Value = the percentage amount of damage.
#_/  To create skills that deal damage only relative to the target's current HP
#_/   you'll make use of <rate_damage Value>. Easy as that.
#_/============================================================================
#_/ Install: Insert above KGC_SetAttackElement, if applicable.
