 * @plugindesc Version 1.0 Allows States to temporarily alter damage types in battle
 * @author Maliki79
 * @help
 * To change a battler's damage type, place the following tag onto state notes:
 * <typeChange_c>
 * <typeChange_p>
 * <typeChange_m>
 *
 * with <typeChange_m> changing ALL attacks to Magical.
 * <typeChange_p> changing them to physical
 * and <typeChange_c> changing them to certain hit type.
 *
 * Note that this alone will NOT alter damage formulas.
 * In other words, if you want a magical skill to ignore magic defence, you'll
 * need to do more than just apply this tag.
 *
 * Note also that there is a preferential order if you have multiple tags active.
 * Certain Hit - Physical - Magical
