#_/  This script allows you to assign skills that "steal" items, weapons, armor
#_/   and money.
#_/============================================================================
#_/                         ◆ Instructions For Usage ◆
#_/
#_/  Setup is simple. To assign a skill as a Steal skill, add the tag "<steal>"
#_/  (without quotations) into the "Note" box on the skill you choose in the
#_/  skills database. Next, to set up enemies you can steal from, in the enemies
#_/  database, you enter <steal X:ID Probability %>
#_/
#_/  Where X = Steal type. I = Items, W = Weapons, A = Armor, and G = Gold
#_/
#_/  Where ID = The specified item, weapon, or armor's ID #, in the database
#_/             OR the amount of gold that can be stolen.
#_/
#_/  Where Probability % = The chance of the item being stolen.
#_/ 
#_/  Example: You have a bandit (enemy) who has a Long Sword and 100 gold you'd
#_/   like to be able to steal from him, at a 50% chance. Tag him with:
#_/    <steal W:2 50%>
#_/    <steal G:100 50%>
#_/  
#_/   New! Equipment that effects steal probability 
#_/    You may define equipment that increases or decreases the odds of the
#_/   steal skill's success. To take advantage of this feature, tag the equip:
#_/    <steal_prob_plus Modifier Rate %>
#_/    Where Modifier = Addition( + ) or Subtraction( - )
#_/    Where Rate = the amount of increase/decrease in probability.
#_/
#_/   Example: You'd like an accessory you created called "Theif's Ring" to
#_/    increase an actor's stealing probability by 15%. You'd tag that ring:
#_/    <steal_prob_plus + 15%>

#_/   System, if applicable.
