Can you “Take Advantage of your Influence” to reduce the roll of “Take a Powerful Blow” by -2 and thereby save them from the Powerful Blow? There has been a lot of disagreement about this at my table and some of the people (Including the GM) thinks the concept feels wonky, and it seems like the most mechanically powerful method of using the rules. To the point where I don’t see the point in giving up your influence in literally any other way. One of the worst ways that A villain can hurt your team is with this move so there is literally not a reason to do otherwise.
Also it seems like the situation causes both the Influencer and influencee to receive benefits. The one using their influence to take advantage gets what they want (You to not fail the Roll and keep fighting) and the Influencee gets the added benefit of passing the roll and not having to worry about influence from the original character anymore. In the other cases of this rule it seems like only the Influencer gains any benefit with the Influencee being high and dry or feeling pretty shitty about the whole thing.
Also, It seems like taking advantage of your influence over someone is generally speaking not very helpful otherwise. Inflicting a condition doesn’t guarantee a result on other PCs, taking +1 on one roll seems pretty useless when compared to just keeping the +1 roll all the time and risking not having the bonus at a critical point in the future.
