The Advanced Player's Guide states that you cannot use the Reposition Combat Maneuver to "maneuver a foe into a space that is intrinsically dangerous, such as a pit or wall of fire."
This makes sense, as the use of the maneuver is, as I understand it, not to grab the target and push/pull/shove them into their new position but, rather, to "shepherd" them there. So, understandably, any foe with any awareness of its surroundings will not willingly step backwards off a cliff - even if an opponent is trying to "out-maneuver" them there. However what if the square you are moving them to is "intrinsically dangerous" but not abundantly obvious - say a deadly trap trigger, for example? Would this limitation of the rule still apply?
Would a house rule allowing for an immediate perception check (at GM's discretion and perhaps with corresponding penalties) by any target being Repositioned into a non-obvious but immanent danger be appropriate?
