[hider=Damage]
Sticking with the theme of 10 as the base I think characters will have 10 hours give or take 1 or 2 depending on things.
Being that, damage will be relatively low.
Each weapon will have important individual stats but here's a rough idea.

1 - usually fists or small rocks
D2 - claws or sharp projectiles (darts/sling)
1+D2 - small blades, clubs, arrows
2xD2 - medium blades, axes, bullets
1+(2d2) or 2d3 - large two handed weapons, heavy fire power.

So the guard with his gun sword, while its technically one weapon, each function has its own stats.

Gum sword:
Sword - d10 potential w 1+d2 damage
Gun - d8 potential w 2d2 damage

[b]Now combining atk and dmg[/b]
One sword attack, 
Opponent doesn't defend
2+d8 = 7
To hit = 5. 7-5=bonus 2
Damage norm = 1+d2 
now with bonus = 1+d4

Opponents armour reduces potential dmg by -1
So end result is 1+d3

Armour

I foresee the best armour increasing the to-hit from 5 to 7 and reducing potential damage by 3. But that should be a magical/mechanical full plate.

Most armours should only reduce potential dmg by 1 or 2
The stronger full body protection also reducing the to-hit potential of a weapon. Ie a d10 becoming a d9 or d8


Armour stats would be as follows.
[u]Chain mail[/u]
Atk potential -1
Dmg potential -1
---
Dodge -1
Block /
Parry /


[u]Hide Armour[/u]
Atk potential -0
Dmg potential -1
---
Dodge /
Block /
Parry /


[u]Steel full plate[/u]
Atk potential -2
Dmg potential -2
---
Dodge -3
Block -1
Parry -1



Still to come:
Defensive manoeuvres, stats, skills and Str bonus dmg
