ohhh! I love this idea. That would really speed up combat, which can be dragged down in PBP. Then I’d change the word of Health to something more akin to “endurance” as a minor blow would still tax your enemy in the sense that it tires them out, even if it doesn’t deal “damage”.
Great thought!
p.s. the pbp game I posted got a ton of applicants once ppl read the PHB. 😄
