// Description:
//    Random heal every x seconds.
//
// Variables:
//    @type
//          0 - Sweeties (lowest)
//          1 - Vegetables
//          2 - Proteins
//          3 - Proccessed
//          4 - Magical (highest)
//   @delay
//      Overrides the lasting time
//   @rarity
//      How rare the item is (how much should it effect)
//      Ranges from 1 to 10.
//
//  Formula:
//      MinHeal %: @rarity * ((@type*1) + 1)
//      MaxHeal %: @rarity * ((@type*2) + 1)
//      Delay: 1 + (@type*2)
//          Sweeties: 1s
//          Vegetables: 3s
//          Proteins: 5s
//          Proccessed: 7s
//          Magical: 9s
//
// *getequipoption(EQI_HEAD_TOP,1,168); → Heal Bonus (should be first bonus on Chef Hat)
