Goblin could probably just extort people instead of killing them.
"Give me 20 Gold plus the revival cost of all your party that you want to survive or die"
Would also reduce how much money the church gets which would probably be a plus for the monsters. Especially if she just circles around and charges them again.
On that note now that I think about it, to revive someone at level 8 someone would have to kill 25 goblins (based on her 1 xp 2 gold joke) which is kind of brutal.
