As soon as I wrote that title, my brain went to “pork chops and applesauce”.
Brady Bunch-isms aside, I recently had an idea about hit points and armor class in D&D-esque games. In terms of combat, hit points and armor class combine to form a sliding scale for determining how long a character or creature can last in combat. Armor class determines how hard it is to “deal damage” to a target, so it is impacted by the form of armor worn (or natural armor) and by dexterity. Hit points represent how much “damage” a target can suffer before it dies, with damage in this context meaning not just physical injury, but also exhaustion and your skill in avoiding telling blows. In other words, there’s a whole lot wrapped up in the hit points concept.
This is all fine and dandy in the context of combat, but hit points are used outside of combat as well. Damage from traps, damage from falling – and that is where it gets a little goofy.
Fighters have more hit points than thieves, for example, because they are more skilled at combat than thieves and should therefore last longer in combat than thieves. But why should that help them survive falls better than thieves? Shouldn’t thieves be better at falling than fighters? And perhaps they are, depending on the system used, via the saving throw system, but even then – a character’s ability to withstand physical punishment outside of combat should have more to do with their constitution score than their fighting ability.
Some games introduce multiple kinds of hit points, or shifting non-combat damage directly to the constitution score, which is fine, but does create more book keeping. I thought of another way to go that is simple and doesn’t require any additional rules or statistics.
First, equalize hit points across classes. Everybody rolls d6 for hit points at each level, and still add their constitution bonus to hit points.
Second, un-equalize the character’s base Armor Class. Using the ascending version of AC, fighter types have a base AC of 12, cleric and thief-types of 10, and magic-user types of 8. Monks use the system they’ve always used. For barbarians, who usually roll even more hit points than fighters, go base AC of 14.
The base AC now represents fighting skill, while the hit points are a representation of one’s ability to survive injuries either through sheer physical endurance and toughness or luck (or both). Fighters can’t take more falling or trap damage than anyone else, but they can survive combat better than everyone else.
