Witchery 0.15.0 is released, highlights:

• Spirit Dimension - Mirrors the real world, use a Brew of Sleeping to get there. Can be nightmarish or nice. Gear stays with your body in the real world! Use a chest if you are scared
  
• Spirit Portals and Rite of Manifestation - Return from the Spirit World though a Spirit Portal as a Ghost, get into secret places unnoticed (remember almost no objects can travel between worlds).
  
• Dream Weaver overhaul - Need string made using the Spinning Wheel with ingredients from the Spirit World.
  
• Dream Weaver of Intensity - Makes Dream Weaver effects stronger (some have less duration then though).
  
• Biting Belt - Something for the leg slot works the same way as Parasytic lice (free potion injection when hit).
  
• Brew of Sleeping - see above.
  
• Brew of Flowing Spirit - Helpful with Spirit World
