Haven't done one of these in a while, but in game I kinda gasped and said "oh wow is this lethal?!" We didn't have enough time to figure it out so went for the safe Velen->Nova play. (Opponent is Grim Patron obv) Spare part is from Toshley.
So... 1. Is this lethal? 2. If not, what's the most amount of damage we can do?
