A knight's Oath of Honor teleports her in the chosen square, cannot be stopped, cannot be targeted by a pit trap in the landing square (she did not enter it, she was placed in it), cannot anything. Syndrael will be able to recover fatigue because she did not move - she was placed! It might even be flavorful with a character like Tomble (hide in the shadows and reappear suddenly and in an unexpected place), but when a knight does it's another headscratcher.
This isn't correct. "Placing" does still count as "entering a space", so something like Pit Trap can be used. Just as it can be used after a figure is Thrown. Trip Wire can not be used because it is not entering a space "during a move action". Syndrael can NOT recover fatigue because she DID move, it just wasn't done using a move action.
Remember that taking a "move action" and "moving" are separate (albeit very related) things. You can actually take a move action and not move. Example: Syndrael could take a move action to trade items (because trading items can only be done during a move action) and not spend any of her movement points on changing which square she was in, and then still recover fatigue. FFG has clarified that if she changes which square she is in during her turn (regardless of method or if she ends up in the same space she started in, that she can not activate her hero ability).
For Pits, if you move on them, you still fall down them and need to take a climb action to get out. It doesn't end your action, but it still prevents you from getting out of it.
He was referring to the Pit Trap overlord card, which does not require climbing out of. This is different than entering "Pit Spaces" which are printed on the board.
