That One Guy said:So, I was thinking about threshold damage minions. They go down when hit by an attack that does >=x damage. So by these zany and fun rules, a Vampire spawn minion (are those stats from the minis?) would have to take 10 or more damage in a single hit to go down.
The /10 is it's bloodied condition. Half it's hitpoint total. That's all that 10 means. It's not damage resistance or anything.
