 *   Jiffy's Move Staling Plugin
 * ===========================================================================
 * Inspired by the mechanic by the same name from the Super Smash Bros. Series,
 * staling will decrease the amount of damage a move does if it is used
 * repeatedly. This will discourage the spamming of the same move and will
 * add another layer of complexity to your combat system.
 * ===========================================================================
 *   Parameter Explanation
 * ===========================================================================
 * damageDecreaseIncrement:
 * This parameter changes the increment of which your damage is decreased by.
 * For example: If I set this to .1, the damage will decrease by 10% each time
 * time it is used in a row.
 * ===========================================================================
 * Thanks for reading! If you have any questions regarding this plugin, feel
 * free to DM me on RPGMakerWeb!
 *
 * Thanks again
