/*:
 * @target MZ
 *
 * @plugindesc ver1.0 MZ - Allows users of DM's Independent Items to set random params to weapons and Armor Equips.
 * @author Maliki79
 *
 * @help You need three steps to use this plugin:
 * 1: Make sure DM_IndependentItems is added to your project properly.
 * 2: Make sure desired weapons and armors are tagged to be Independent Items.
 * 3: Tag Weapon/Items with <maliiRandomParams: x, y> with x being the param number and y being the max range.
 *
 * Param numbers are as followed: 0 = MaxHP, 1 = MaxMP, 2 = Atk, 3 = Def,
 *                                4 = MAT, 5 = MDF, 6 = AGI, 7 = Luk
 *
 * You may use as many of this tag as needed and the plugin will add all the same params together to get the max range of randomness.
 *
 * So for example, if you use the tag <maliiRandomParams: 2, 20> on a weapon or armor with 70 atk,
 * The plugin will randomly give the equip an atk value between 50 and 90. (70 +-20)
 * The value can potentially go into the negative.
