Invisibility Cloak

Known Behavior
The invisibility cloak is a clothing on the body that has a magical effect. As its name states, the invisibility cloak grants invisibility to the player and other clothings when worn, and it can be used as a stealth item. NPCs are unable to detect players unless contacted (cannot detect after moving far away) or attacked.

Trivia

 * The cloak isn't invisible. This is obviously because players can't see the item if it is invisible and will lead to confusion when using it.
 * Odd enough, if you hold an edible object while wearing the invisibility cloak, NPCs can somehow detect your position. Logically, this maybe the cause of smelling.
