Editing Ravenloft Campaign (section)

====Transient Planes====
Ravenloft, as a demiplane, does not truly touch the ethereal, astral or shadow planes as the Prime Material does.  Nevertheless, Ravenloft does have a singular planar space similar to the transient planes.  All spells that make use of any of the transient planes instead make use of this space.  This plane, however, is not the same as normal transient planes.  Characters in this planar space may not not cross domain borders, may not pass through physical objects and must remain on the ground (unless they also possess the ability to fly).  This means that teleportation can only bring you places you could otherwise access without passing through physical objects, and effects like blink do not allow one to pass through walls or move upwards away from the ground.

Additionally, the nondimensional spaces between the planes surrounding Ravenloft are inhabited by awful, incomprehensible gibbering ''things''.  And traveling between the planes attracts their undue attention.  Any time a character travels between different planar spaces, they arrive on the other end covered by unexplainable claw marks, bite marks and lashes.  In addition to being disturbing, this inflicts 3d6 damage and leaves the character with the unnatural touch of 1 taint.  For spells with an instantaneous duration (like teleport), this happens once upon traveling.  For spells like an extended duration (like blink), the damage occurs once a round and the taint occurs once at casting.  When passing only part of one's body through the planar fabric (such as when reaching into a Bag of Holding or Portable Hole) only 1d6 is inflicted, and no taint.

Finally, extensive planar travel may attract the attention of the Dark Powers, who have the ability to interfere with its effects.  Let the GM know when you use one of these effects.  This boils down to a percentile roll.

Spells, that draw material in from other planes function normally.  Creatures remain trapped after the spell's expiration.  Inert material dissolves away into mist.
