Trace Teleport

Information; Resisted by subject spell 
When cast soon after someone or something teleports, or plane-shifts in or out, this spell gives the caster a vision of the destination of the teleported subject. The caster also gets a good idea of the magnitude of the skill penalty involved to cast the spell. On a critical success, the actual destination will be known, but any success gives the caster enough of a sense of the destination to follow, if he does so within a minute of casting Trace Teleport.

Modifiers: The spell operates at a cumulative -1 for each minute that elapses between the teleport and the casting. There is a further -5 penalty if the caster didn’t witness the teleport. 
Cost: 3. 
Prerequisite: Teleport, or Plane Shift (VH).

Item 
Any.  
Energy cost to create: 100.
