This door Knob is only useable by whoever is attuned* to it.

Ownership is revoked if the current owner attuned owner dies.  The door will persist through any and all types of damage or destruction. 

If the door still exists upon the death of the owner, it will ask 3 Questions or Riddles to whoever come across it. (See Attunement) 

When placed on a wall, floor, or ceiling with at least a 5 foot space on the other side, a door will appear, allowing the owner to walk through.

This artifact can only summon 1 door before needing 24 hours to recharge.

Once a door is summoned the preceding summoned door vanishes.

Anyone else who tries to enter,  or open the door, will be teleported to the closest empty 5 foot or greater space, inside a bathroom, outhouse, or other purposed area. 

*Only use Attunement if your campaign supports it and / or you already have or are planning to use a riddle dispensing magical door.  If you do not use attunement then it is only useable by whoever first finds it.  If not using attunement, and the owner dies, the door vanishes and the door knob falls to the ground.

Notes: person answering 3 riddles or question given to you by a magical echanted door. If you are correct all three times, the Door disappears and is replaced with a Simple Looking Door Knob (Zonicus Chaotica's Magical Door Knob)
