Aggravating people worldwide since 1964
Yes Joe, this is perfectly correct, but don't forget to play the Milady card because you can't charm a Baron without using it (even if your Milady is adjacent or in the same space of the Baron). The card is always necessary to activate Milady's power, also when a plague-striken Milady declares infecting enemy pawns (adjacent or in the same space).
Thank you! Hopefully, I will have a chance to play this for the first time tomorrow.
