Arcadian Knight
Well, no, actually you make the attacks, so Pacifist Healer certainly burns you there. All the spirit does is act as the point where range is calculated for Spirit powers, and LoE and LoS.
Feels like splitting hairs ...oh you summon the spirit and the damage is always described as being the spirit doing the damage and its from there position... but since they are your at-wills... its you doing the damage ... but ... I can almost see it from the characters pov he is manifesting and intimately connected to the spirit and would quite reasonably be fully guilt ridden even if the spirit is doing the attacks... true pacifist could have issues with his allies attacks unless he makes active attempts to convince them otherwise.
