Amulet of the Inner Self

This amulet is of simple make, made from silver with a small gold eye in the center surrounded by a maze like pattern.  A small star sapphire adorns the center of the eye.

This item allows the wearer to focus their Ki and extend their senses outward.  The amulet has the following effects, each useable once per long rest as an action and lasting up to one minute: Blind sight or Tremor Sense (but not both to a distance of 30ft, users choice), Detect Thoughts and See Invisible.  The wearer may also use Clairvoyance but must expend one Ki point in order to do so.

Notes: Sense: Blindsight, Sense: Tremorsense, Monk
