Женя ты не прав.
GaP (Game as Played. Where there is ambiguity a missing rule or downright nonsense in the way something is worded, this is the way the majority of players will play the game) - собственно так выделяется т.н. хоум рул.
Clarification (clearing up a rule or some ambiguous wording) - а так выделяются вещи о которых люди долго срались на иноземных форумах, спрашивали у троллей и т.д. Это вытекает после прочтения кодекса эльдар и рульбука и вполне логично.
По поводу когда кастовать синапс:
Q: When does a psychic power use the shooting rules and when does it not? The descriptions of the various powers and the rules in the BGB (page 52) suggest they all do and I cannot find any which are "specified otherwise".
A: The BGB doesn't actually contain any such powers, the various Codices do. The wording in the BGB leads to much confusion. The best approach is to read it as "Some powers work like shooting and will state they follow the normal shooting rules. Other powers will have their own rules for use". [GaP].
По поводу вопроса:
Q: Can a Hive Tyrant or Zoanthrope use more than one Psychic power per turn?
A: For the sake of consistency, I would say that only one power that requires a Psychic test may be used per turn. However, most Tyranid powers are “always active” anyway, and these don’t interfere with the model’s other powers.
