1st of all sorry to whoever ends up moving this that its in the wrong place. My bad
This makes no sense at all.The average armour values are a good bit higher than what you have posted, and what if i wear full plate will that mean im -4 slots or just 1?
Just the 1 slot used. Its non stacking so your 1 slot used for body armour would not stack on top of any slots used for helms, gloves or boots. I thought about a system that increases the number of overall slots and counts each individual piece of armour but this actually works out simpler imo. You either decide to be heavily armoured and sacrifice a weapon slot, or you decide to be lightly armoured.
To answer other comments
I picked a value of 30 for body armour as this is where the armour suddenly jumps in weight from approx 5 to approx 10. I see no reason to distinguish between chain and plate because plate armour, although potentially heavier, was in fact easier to wear due to it being in pieces that were individually supported by didfferent bits of the body rather than all the weight being on the shoulders.
The other stuff I just picked what seemed logical as a peasant with a full plate helmet would look a bit silly. An alternative would be to say that if your total armour weight exceeds 10 then it costs a slot. I think my system gives people more choice though.
As for slots, 4 is more than enough imo even with a slot taken up by heavy armour. People still have plenty of options. There will be no change for light armour wearers whilst heavy armour wearers still get 3 slots to use on either
Heavy Shield + 1 Hander
Normal Shield + 1.5 Hander (Bastard Sword)
Normal Shield + 1 Hander + Throwing Weapon
2 Hander + Throwing Weapon
2 Hander + 1 Hander
1 Hander + Lighter Bow/Xbow & Arrows/Bolts
Lighter Bow/Xbow & Arrows/Bolts + Normal Shield + 0 Slot Weapon (Hammer)
Heavier Bow/Xbow & Arrows/Bolts + 0 Slot Weapon (Hammer)
That's plenty to be going on with just off the top of my head
What awesomeasaurus said was exactly what I was going for. Making people choose between attack and defense although it doesn't actually limit peaople that much.
The only thing it stops is things like Heavy Xbow + Heavy Armour + a good Melee Weapon of some sort which is good imo as it stops people being able to have both great ranged weapons, great melee weapons and great armour. You get 2 out of 3 instead
