That is not correct.
1. LoS. Z could not have possibly had LoS unless she Ravened and then that would mean she could not have summoned a doll.
2. Where does it say they take 2 Wd?
This is the official ruling on Poison:
When a model is hit by an attack with Poison # or affected by an Ability with Poison #, increase the number of Poison Tokens the model has to the # indicated either after resolving the attack, or as indicated by the Ability. Each time the model begins/starts its activation it suffers 1 wound per Poison Token it has, and then discards one Poison Token.
This was played incorrectly if that is how it was played. I play Z and I love her, but she can't just pick any model on the board to Conduit and she definitely can't cause 2 Wd an activation just by doing Conduit.
I wish she could, but she can't.
