Shaper of Worlds
I'd like to offer this, then:I'd note that playtest materials don't necessarily mesh with each other; sometimes they're playtesting different things to see what works.
To go with:Wounds
Whenever a character is subjected to certain situations the loose hit point definition doesn't really encapsulate the sort of damage they should be taking. To facilitate this kind of injury, we use a tracked condition called Wounds. Each wound you sustain advances your position on the Wound track, which ultimately leads to the Doomed state. You gain Wounds under the following circumstances:
When you are subjected to a Critical Hit you take 1 Wound.
When you are at 0 hit points and struck by a melee attack you take 1 Wound.
You may also sacrifice a shield that you are wielding when subjected to a Critical Hit to negate the Critical Damage and the resulting Wound. If you sustain Wounds during combat you should keep track of them, but do not apply any cumulative penalties from the Wounds until after combat has ended. This represents your character's ability to ignore severe pain and trauma due to adrenaline, willpower, or magics.
And of course:Wound Track
1) Your movement speed is halved and you are unable to keep up a fast pace.
2) You are capable of only performing an action or a bonus action on your turn.
3) You take double damage from all sources, unless you have Immunity. Resistance applies normally.
4) You have disadvantage to all saving throws, including death saves.
5) You are Doomed to Die.
By creating another kind of Tracked Condition you slow things down a tiny bit, but it easily conveys your intentions without causing overlapping issues with Fatigue or Strife.Wound Recovery
For every twenty four hours of rest you take, you may reduce your current Wound count by 1. During this time you must remain confined to a bed, bedroll, or similar place of rest, receive aid in eating and drinking, and may not perform even light activity.
Certain magics, such as Regeneration or Restoration, can reduce your Wound level by 1 per casting.
Bonus points: They all three stack!
