This shadowy black to dark blue robe appears to move as shadowy mist along your body, intricate looking lines of smoke or shadow seem to form and unform as it sits at rest. If one looks at it for long enough, its said the appearance of a face, or hand, will seem to form out of the moving shadow. A face the seems to be silently screaming, Only to disappear just as quickly.

You gain a +1 bonus to persuasion or Intimidation checks while you wear it.

Created through the temporal reversal of necromantic magic previously infused into the robe, It seems to affect and warp the reality around it as Time and Gravity based magic is used. 
When ever a Spellcaster uses a Dunamancy based spell while wearing this robe, it causes one of the following effects to be projected towards a specified target in a cone. 
1) Up, up & away: you pulse out gravity waves Moving any creatures or items within 15 feet of you in any direction 15 ft (weaker telekinesis)
2) Entangle: you cast the grasping vines spell. 
3) Enchanting Gaze: under the effect of a minor love potion for 1d4 hours/1d4 rounds if in combat and visibly dazed
4) Hideous Crying: Sounds amusing as opposed to laughter, Your target is affected by a 4th level Tasha's Hideous laughter. 
5) Void: a Gravity warp opens at your feet, and you You magically twist space around another creature you can see within range. The target must succeed on a Constitution saving throw (the target can choose to fail), or the target is teleported to an unoccupied space of your choice that you can see within range. The chosen space must be on a surface or in a liquid that can support the target without the target having to squeeze." 
6) You case the Web spell, the area is 120feet instead of 60

 Additionally: Once per Long Rest you are able to cast Quantum Flood from the cloak, causing everyone with in 60ft to experience one of the listed effects (Decided by rolling 1d12)
