Amulet of nature

An Amulet of nature is used to monitor the state of a Farming patch. It can only be bound to one patch at a time, and will remain bound until a different patch is used. It can be bound to any type of farming patch. If the state of the patch that the amulet is bound to changes and the amulet is worn, it will vibrate. This should allow the wearer to detect when the patch is diseased or fully grown. This feature will only show up if you're online at the time and ONE time when you log in, but you can also rub the amulet at any time to find out the current state of your patch. You can only have 1 Amulet of nature at a time and, once enchanted, it is nontradeable. You can protect 2 crops if using an Amulet of Nature. 
An Amulet of nature can be created by stringing an emerald amulet with magic string to make a Pre-nature amulet. Casting Enchant Level 2 Jewellery on it will result in an Amulet of nature. After enchantment, it is not tradeable. However, Pre-nature amulets are tradeable. Many players will sell the amulet when it is in an unenchanted state. Alternatively, a player may buy the string itself, which is tradeable.
