#      Instructions:
#  Place this script in the "Materials" section of the scripts above main.
#  This script has no customization options and is plug and play.  To use this
#  script just follow two fairly simple steps.
#   1. Create a state with the passive buffs you would like a skill to add.
#   2. Add the line "passive[x]" without the quotes to a skill's notebox where
#      "x" is the ID of the state to be applied while the skill is learned.
#      Note that passives do not apply to enemies.

##-----------------------------------------------------------------------------
#  The following lines are the actual core code of the script.  While you are
#  certainly invited to look, modifying it may result in undesirable results.
#  Modify at your own risk!
