This feat is only used when you are an echo knight and it allows you to see and speak to any ghost nearby. 

As an echo knight, you can use one soul you have on you to summon the soul as your echo, this echo gains one ability of the orignal soul (DM gets to pick) and has the normal stats of an echo. The new soul echo has its own consciousness and gets to decide what it does and it uses your equipment and slots.
