Turn question.

Sorry but I don't have the name of the cards because my friend has the Rook CIty expansion but Spite has a drug that says something to the extent of the first time Spite is dealt damage this turn prevent 3 of it, it may be an H but for our game it was 3. So anyways what defines a turn? Is it from the Villain Turn to the Environment Turn? Or is the Villain Turn, Hero Turns, and the Environment Turn each different turns? Or is each Hero Turn counting as a new Turn? I thought that from the Villain to Environment is one turn so if we were to damage Spite on the Villain Turn we would be able to damage him without the drug reducing the damage. But my friend thought that each Hero Turn was a new "Turn" so when Legacy would first do damage it would be reduced then after him when Haka would deal damage for the first time that turn it was also reduced. I am sorry for this being a mess but I can't think of a better way to ask it. 

The villain, the Environment, and EACH Hero has a turn.  Spite's effect will reset for each of those turns.

From the start of the villain turn to the end of the environment turn is a round.

Thanks!
