When characters return to the Hexadom from the bench and can be placed in a designated deployment zone can they be placed as they are deployed in the Assault scenario for example and be placed in a zone or an adjacent square to the zone or just inside the zone? Thanks in advance.
They must within the zone not adjacent. However they can be in any of the remaining six of seven zones other than the current scoring zone. A deployment zone really refers only to the very first turn.
Can you spawn adjacent to your opponent's chatracters? As in after a zone is scored and changed, assuming you win initiative, can you first action bring Massacre or Musashi into play next to the Gata that scored last round and send her to the infirmary?
Yes, you may spawn adjacent to your opponent's characters. I would hope that your opponent playing Gata would put her initiative card first in order so that her 7 trumps Mushashi's 6 or Massacre's 5. However if you have Parvati on your team and Field Analysis in your hand the extra 3+ on initiative may allow you to spawn next to her, trump her initiative and most likely send her to the Infirmary.
