Trying to solve the weakness of Low-Tech armor with no modifications on ST damage tab

[Rasna]

I know, this topic has already been discussed several times. This is just my way in order to reach the maximum of realism without changing the DR of armor, the ST damage table and the damage bonus of most low-tech weapons. It isn't a "quick and dirty" solution, so it isn't adequate for those who don't like doing much extra math.

The solution isn't nothing new: armor divisors!
The main innovation is the extensive use of different armor divisors based on the type of damage, the form of the weapon and the material of both weapons and armors.

Armor is divided in three main categories: non-metallic armor (bone, cloth, horn, leather, straw, wood), metallic armor (bronze, copper, iron, steel, stone, TL 1-4 reinforced cloth/leather) and hardened steel armor (the latter is distinguished from metallic armor only for impaling and piercing weapons made of hardened steel, which they're more effective against ordinary metal armor but not very much against hardened steel armor).

Weapons behave differently because their form, their material, their balancing and the material of the armor they try to defeat, so a lot of them have a split armor divisor, one against metallic armor and one against non metallic armor. -
- Unbalanced crushing weapons made of metal (maces, pollaxes, flails) and piercing weapons (bec de corbin, ahlspiess, warhammers, bodkin arrows) are the best anti-armor weapons, so they maintain the (1) armor divisor. For their relatively high velocity compared with other low-tech ranged weapons, most single-shot firearms also get (1) armor divisor.
- Impaling weapons are more effective against non-metallic armor: most of them have armor divisor (0.66) against metallic armor, but they maintain the (1) armor divisor against non-metallic armor.
- Unbalanced cutting weapons (swords, khopesh and eplison axes excluded), unbalanced wood or balanced metal crushing weapons and piercing weapons made of soft metal (ex. lead sling bullets) perform a bit worse against armor. They get (0.66).
- Unbalanced swords, like dao and falchion, are more effective than ordinary swords against non metallic armor, but they aren't good as axes against metallic armor. Same thing for impaling weapons with multiple striking points, like the trident. They get (0.5) against metallic armor, but (0.66) against non-metallic armor.
- Broadheaded impaling weapons such leaft-shaped and hunting arrows seems to be more effective against cloth or leather armor, but they're less effective against metallic armor. They get (0.5) against metallic armor, but (1.5) against non-metallic armor.
- Balanced cutting weapons, the flat of blades, balanced wooden crushing weapons, unarmed attacks and stone piercing weapons aren't ideal against any kind of armor. They get (0.5).
- Metal weapons of fine/very fine quality and/or made of hardened steel improve their armor divisor against non-metallic armor (cutting attacks), or both metallic and non-metallic weapons (impaling and piercing attacks), but not against hardened steel armor.
- Low-tech materials (bone, obsidian, stone, fire-hardened or unhardened wood) generally perform significantly worse against armor, especially for cutting and impaling weapons.

Here is the table.
