Armor for Mixed and Modern Settings

Shields

Shields don't have to change at all. However house rule shields are applied to touch ACs. The new DR Armor doesn't change AC so this makes one less thing you have to keep track of as normal AC is just touch AC.

Damage Reduction Armor System

This system is for if you want to mix tech levels and keep it interesting. With this system your armor has very little effect on your AC so it makes more sense to think of AC as DC to attack or Attack Class. even so for compatibility we will still call it AC.

Damage Reduction

Damage Reduction(DR) is the value remove from damage done each attack because of your characters armor. Each time damage gets by the DR the DR is reduced by one. When the armor is reduced to 0 DR it is disabled, still encumbering the wearer, but no longer providing any protection.

A sunder attack against armor can reduce its DR by multiple points. Attack as normal but any damage that gets past the DR is instead applied to the armor after reduced DR until the damage no longer exceeds the DR or the armor is disabled.

For example a sunder attack for 15 points of damage against armor with 7 DR would be applied thus:

Or 10 sunder damage done to DR 3 armor:

Armor repair

Armor that has lost DR can be repaired. An armor patch kit costs 1/20th of the base cost of the armor. It takes 15 minutes to repair armor that contains only soft layers and 1 hour to repair armor including hard layers. The DC to repair any damage is 20. The DR recovered by the repair is equal to the craft roll times the remaining damage to the DR divided by 40. Minimum 1 DR repaired, if the 20 DC is exceeded. A character can hastily repair a suit of armor as a full round action by taking a -10 to the repair roll.

 DR recovered = (Repair Roll * DR missing)/40

Energy Armor

Weapons that do not normally ignore the energy armor must be linked to the field generator to coordinate an instantaneous shutdown of the field when attacking.

This cost $100 per ranged weapon, vibro or energy weapon.

Metal normal melee weapons in contact your hands are automatically linked to a magnetic field generator and are treated as a vibro variant of that same weapon if applicable.

Generic Armor

For a classic DnD game the DnD armor system is fine. You could make a generic armor system mostly just reskinning the DnD Armor.
