Must the direction of a pull remain the same for the entire pull, or can the direction the target is pulled in change mid-movement?
One example: Say I use an ability to pull a target two squares, but after only one square, moving the target again in that direction would no longer be viable (an obstruction appears, etc). Will the target continue to be pulled? Can or should it change to a viable direction?
Another example: Say a Caster (C) and her Target (T) are standing like this (where o is an empty square):
T o o o o o o C o
Would pulling the target two squares to the target's east be a viable pull, or would it be unviable after one movement because the target would have to be pulled downwards too?
