[@amorphical] If they are both feeding off each other at the same time then there probably isn't much gain. I think it would vary on each situation though depending on which types are involved - if they are lovers and feeding in the heat of the moment then an emotional or sexual type blight born is going to get a lot more out of that than the rest of them would. They'd have to be careful not to totally over power the other person involved and avoid killing them as well haha
