The Two Way Mirror

You touch a number of willing creatures up to your spell modifier (minimum of 1) and for the duration all those affected can travel between mirrors like hidden passages. while in the mirror realm you cannot be seen by those outside the mirror unless that person has also been through the mirror realm. 

The mirror realm is a maze of hallways and mirrors linking all the mirrors of the world together. you can only enter and exit through a mirror but you can see out of any reflective surface while inside the mirror realm ex. a pond.

once a person has been affected by this by this spell and its ends they cannot regain the effects of this spell if cast again until the next dawn.

if this spell is cast at a level of 7th or higher the number of creatures affected increases by one for each level above 6th.
