I'm looking at the codex and in note 3 of the wargear it says that the kiss may not be used with a power weapon. I does not mention the powerblades, and being as the powerweapon and kiss are both in the singlehanded weapons section it kinda makes sense. However it makes no mention of Powerblades, and powerblades are in the wargear section. Does it not make sense that wargear effects add to weapon effects?
