Ascending Damage & Dicing With Death

The rule

You no longer have hit points. You have a Wounds tally - the higher it goes, the more badly you've been hurt. You start at 0 Wounds. Whenever you are hit by an attack, you suffer 1 Wound. (This replaces HP damage. Damage sources that would deal multiple dice of damage deal one Wound per die of damage.)

You have a Maximum Wounds number from your class table (modified by CON - note that there are no negative ability modifiers, as per this previous post, so Max Wounds is always at least 1). If your Wounds exceeds your Maximum Wounds, you must Dice With Death: roll a d20. If the result is below your current Wounds, you die. However, if the result is above your Constitution score, you fall unconscious for 1 hour.

While above your Maximum Wounds, you must Dice With Death again each time you take further Wounds. Additionally, you have -2 to attack rolls and AC.

The rationale

Dying and initiative seem to be the two topics that I re-tread over and over, no matter the system I’m playing. I recently realized that “Health” as the number of hits to kill a PC from my earlier post (which replaces rolled damage) would pair perfectly with an ascending damage system. That is, one where you tally up the damage you’ve taken on your character sheet, instead of subtracting from your hit points tally.

In the regular D&D system of HP and damage rolls, there is uncertainty at first, followed by certainty: first, you take variable amounts of damage, but once you’re at 0 HP, you’re dead (or unconscious or whatever it may be). The mechanics move from dynamic to static as play progresses. On the other hand, this proposed system of static damage (1 Wound per die) makes things… well, static and predictable at first. But Dicing With Death makes the next phase dynamic and uncertain. It flips the script of the adventure around, as it were: the uncertainty of rolling is moved to the later, higher stakes part of the game. As the adventure progresses and resources dwindle, uncertainty goes up. And, thematically, that makes sense, right?

(By the way, there exists a third system that differs from both the “dynamic to static” and “static to dynamic” systems. It’s the “static to static” system where a hit is a hit and death is death. Such a system was used in the very early days of the proto-D&D game which was based on Chainmail. Characters simply had “hits to kill” - so instead of having two hit dice, you could take precisely two hits, and then you were dead. For example: "Ogres are killed when they have taken an accumulation of six missile or melee hits in normal combat". As mentioned in the previous post, these “hits” were only later expanded into the more incremental system of hit point rolls and damage rolls, when players complained about dying too quickly. And that’s where hit dice get their name.)

I have always been fascinated by mechanics that add uncertainty at the point of (near-)death. Uncertainty means tension. However, damage rolls are not tense, because they’re routine and average out in the long run. They’re only tense when you’re very low - if you have 6 HP, then the trap’s 2d6 damage roll is the difference between life and death. But up until you get to that threat range, the damage rolls don’t matter, and you might as well just take the average result every time.

"Death spiral" systems, i.e. ones where your fighting capability falls linearly as you take damage, are bad for a different reason. They remove uncertainty up front: whoever gets hit first has probably lost, and the result of a fight is decided and obvious from the beginning..

Essentially, what I have done is extended the relative space of play where a single roll decides the fate of a player character. However, I haven’t made things more lethal overall. In fact, I’ve given players slightly more resources - first they lose their health, and then they get complications, while still having a chance to survive. You could perhaps call it a safety cushion, but the important thing is that the risk is real (unlike, say, 5th edition’s death saves which make it virtually impossible to die). At the same time, I’ve given players more rope to hang themselves with (which is always more fun). In an HP damage system, getting knocked out can be sudden (and double damage critical hits exacerbate the problem), but after it happens there’s nothing players can do about it that. But here, if they’re badly wounded and dicing with death, they always have the option to keep fighting and exploring. If they don’t want to retreat, it’s their own choice.

Compatibility & benefits

D&D with static and ascending damage might look very different to the D&D you know. However, it should be reiterated that this is all entirely compatible with existing materials and modules. When you play a module and it says you take 3d6 damage, you instead take three Wounds. The majority of the time there’s no maths involved in conversion - in fact there’s less maths than when playing normally.

Apart from cutting down on maths and redundant rolling, the Wounds tally system also has a logistical benefit. Character sheets get worn down more from erasing than they do from writing on them. When you play with descending HP, you have to erase a number and write a new one every time you take a hit. When you check a box each time you take a Wound (unlike HP, the maximum number of Wounds is small enough to reasonably be represented as checkboxes on the sheet), you only need to use an eraser when you get healed. And healing is a less frequent occurrence than taking damage. Therefore, you're saving trees by playing this way!

Optional rules

Though these reduce the elegance of the system, I may add them later to tweak the lethality once I see how it works out in playtesting. As always, everything is just theorycrafting so far, unless otherwise stated.

Critical Failures: When you Dice With Death, if you roll exactly your current number of Wounds, you suffer an additional Wound from internal bleeding (and must, therefore, Dice With Death again).

Adrenaline Spike: One exploration turn after any combat or chase in which you have Diced With Death, your adrenaline runs out; you must Dice With Death one more time, unless you have been healed down to your Max Wounds or below.

Static damage & different weapons

• Daggers have a -2 penalty to hit against defenders armed with long weapons. (That means things like swords, spears and polearms.) This does not apply to unaware targets or those who are otherwise unable to defend themselves. 
• Two-handed weapons and crossbows are Devastating. On a natural 20, they deal an additional Wound. Other weapons don't get to do that. 
• Unarmed strikes and improvised weapons (torches, thrown rocks, etc.) only deal damage on a successful Open Doors roll (2+STR in 6).
• Fighters get some other neat bonuses to make up for losing the bigger damage dice - more details on that in a later post.
• Leader monsters and monsters in modules listed with maximum HP may be counted as one HD higher (take 1 Wound more to kill than normal). For example, if a den of goblins (HD 1 = 1 Wound) is lead by a chieftain with 8 HP, then count the chieftain as HD 2 when determining Wounds to kill it.

Bonus: Other potential uses for “roll-between” mechanics

 Notice how when you Dice With Death(tm), you're trying to roll above one target number but below another? Just spitballing, but:

• When you hit with a two-handed axe, if the attack roll is below or equal to your Strength score, you sever a limb.
• When you hit while dual-wielding light weapons, if the attack roll is below or equal to your Dexterity score on your attack roll, you deal double damage.
• When you are parrying with a lighter weapon, if the opponent’s attack roll misses but is above your Strength score, your weapon is flung from your grasp. Otherwise, if the attack roll is below or equal to your Dexterity score, you get a free counterattack.
