Whisper kicks my ass in 2-3 turns, using things like unbreakable or kaelirra's tears spam doesn't work because he kills so fast. Do I have to kill the correct whisper by chance on turn 1 or 2? killing all 3 seems impossible given the hp and damage output, for some reason they do between 50-100 damage per attack while they're all dual wielding so if they focus a character they're dead. I'm using Cait and Brienne, both level 6, I've tried a variety of builds on mc to no effect
