I don't know, Warren having telepathy maybe a logical type of defense against that kind of magic, besides emotions come from the brain.

And you saw how those white tendrils when in contact with some people who had not been effected from indirect contact of the spell started feeling joy. So perhaps an absolute effect is to be in contact with your target.
