Foresight (Enchantment for Helmets)

     Premonition would be an exclusive enchantment for helmets, and would be available in an enchantment table and as treasure. When a player is wearing a helmet enchanted with Premonition they will be warned of any entities approaching from behind. For example if a player was mining and a silent Creeper attempted to catch them off guard, an arrow would appear on the player's screen warning them. Premonition would come in three levels, each with a larger detection radius than the last.
