Can the feat "Step Up" be used if the 5' step away from you is to the left or right rather than directly away? Can it be used if the 5' step away from you is actually diagonal and past you?
Basically:
PC Fighter= @
Orc Shaman= %
A|B|C
D|%|E
F|@|G
Does the Orc only provoke the use of this feat if he moves into A, B, or C? Can I use the feat if he 5' steps into D, E, F, or G?
