Sorry Sage! Didn't realise you'd posted that idea before
Edit (on topic post - didn't want to double post):
I think this was suggested or mentioned earlier - but I'm in favour of energy/strength instead of health as such.
Your strength determines the speed and power of your blows/reversals - and acts as an automatic buffer for the auto-block.
Blocks will drain your strength and put you on the back foot; requiring a short recovery before you can attack/reverse (but you can still roll/dodge to disengage).
If as your strength wanes you will be unable to block the more powerful attacks and will get hit for full force.
Getting hit drains much more strength than blocking the hit.
Strength the majority of strength loss should be recoverable within a fight - but a certain amount of trauma is going to take additional time/sleep/food/whatever to heal. Obviously the amount of trauma would be practically none from a block and much, much more for a heavy blade or point.
Run out of strength and you pass out.
If trauma takes you into minus health you die.
Being passed out slows your strength regain but counts as rest so you can heal some trauma.
I'm sure everyone understands this: but i'm avoiding work so I'm going to take the time to do a short visual explaination below
Our intrepid Hero Turner is at full strength (10 points)...
Turner |00000|00000|
Blocks a hit losing a point of strength...
Turner |00000|0000_|
And is then struck hard while reeling losing 4 Strength (and taking 2 trauma)...
Turner |00000|___XX|
Turner dodges about and defeats the rebel bunny (foot+face=win) before pausing to get his breath back...
Turner |00000|000XX|
The trauma will take much longer to heal and requires calm (cannot heal during fighting). If Turner has no more opponents and stops running and jumping about the place for a bit he can heal the trauma and regain his full strength...
Turner |00000|00000|
I'm fairly certain much of the system is similar to this - but then I'm remembering bits and pieces from all over the place so i could be misinterpretting something.
