 -Effects Manager
  (http://himeworks.wordpress.com/2012/10/05/effects-manager/)

--------------------------------------------------------------------------------
 ** Description
 
 This effect is activated when an attack is successfully made.
 The user will take some amount of damage according to the effect.
 
--------------------------------------------------------------------------------
 ** Installation
 
 Place this script below Effect Manager and above Main.
 
--------------------------------------------------------------------------------
 ** Usage
 
 Tag effect objects with
 
    <eff: recoil_damage formula element_id>
    
 Where the formula is any valid ruby statement that evaluates to a number.
 
 The `element_id` is the ID of the element you want the recoil damage to be.
 Look up the ID in the Terms tab. If you set it to -1, then it will be the
 "atk element" of the target which can be set using features.
