Prerequisite: Proficiency with all armor and shields as well as strength and dexterity scores of 13 or higher.
You are at your best with armor on your chest. You may use a bonus action to partially don your armor if it is within 5 feet of you and you have a free hand. Until the start of your next turn, you have a bonus to AC equal to half your armor class when wearing armor (rounded up). Each time you are hit, reduce this AC bonus by 1. If the bonus drops below 10 + your dexterity modifier, you drop your armor. You do not gain any magical benefits from armor when it is donned in this way. At the start of your next turn, you must either drop your armor or use an action to don it. Once you don your armor in this way, you must finish a long rest before you can do it again. Your movement speed is halved while your armor is partially donned in this way unless you are wearing light armor.
In addition to the above trait, chose 1 of the following options:
- When wearing heavy armor, you may add +1 to your armor class. This bonus does not apply if your movement speed or dexterity score is restricted in any way.
- With medium armor, you can give yourself resistance to all non-adamantine weapon attacks for 1 round whenever you don your armor and you can don your armor in 1 minute.
- When wearing light armor, you may add half your level to saving throws against an effect that would reduce your movement speed.
