Armor Savant (5e Feat)
From D&D Wiki
Prerequisites: Proficiency with medium and/or heavy armor and Strength of 15 or higher
Your experience and skill with your use of armor allows you to deflect damage.
- Increase your Strength score by 1, to a maximum of 20
- While wearing medium or heavy armor you can reduce non-magical damage by your proficiency bonus + 1/5 your level rounded down. You must be aware of the attack. This will not apply if you are attacked from behind, asleep, surprised, unconscious, held, restrained or otherwise incapacitated. If the armor you are wearing is magical armor, you may reduce the damage taken from magical sources as well.
