Armor Enhanced

This feat is an additive feature, typically used in conjunction with Combat Enhanced (another feat) to add more complexity to 5e armor. These additions, look to give mundane armor more unique features and reasons for choosing any particular type. Note, everything here is purely additive to the core rules and options of 5e.

Listed below are some of the common armor found in 5e as listed in the PHB. The following list will contain the additional features added to each type of armor.

Repairing Armor

Armor may become damaged in conflict and battle. To repair a suit of armor, certain tools are required, either leatherworkers' or smith's tools. This is determined by what kind of armor you have. Repairing armor requires at least 2 hours per AC recovered and one hundredth the average gold cost of the armor in materials. If you have proficiency in the tools required to repair the armor further quarter the cost of materials and half the time of repairs. Expertise further quarters the cost and reduces the time by half. 

Modifying Armor

 Armor may be modified in downtime with the appropriate allocation of gold and time, either adding or reducing certain properties. It is impossible to remove a trait entirely, though the level of a property can be reduced or increased. Protections cannot be added or modified unless the armor started with that protection. Talk to your DM about how much time and gold an addition to your armor may cost and if a forge or any other infrastructure is necessary. Proficiency with leatherworkers' or smith's tools is necessary for modifying. Only non-magical armor can be modified, and any particular armor may only be modified with a maximum of two modifications.

Light Armor

Medium Armor

Heavy Armor
