In my idea a character has half his hit points replaced with the same number of vitality points and the other half with wound points. Critical hits do their normal damage but it is applied to the vitality points first, a critical hit is fluffed as an exceptionally dangerous attack, to get out of the way of a critical hit requires a lot of stamina. All of a character's vitality points can be recovered by resting for 10 minutes. A Fighter type character could also spend some vitality to make special attacks.
- Sample Special attacks
Whirlwind Slash: Gain an extra melee attack, can not attack same target twice.
Mighty Bash: Free trip attempt on a successful melee attack.
Lunge: As an immediate action extend your reach by 5 feet.
- Upsides of this change:
- The party should be less dependent on healing magic to get through an adventure, they can just stop to catch their breath and continue on.
- Fighters are given a resource they can spend to do something other than just make another vanilla attacks.
- Downsides:
- More book keeping
- Probably requires new fighter feats for the special attacks to work well
