Gauntlet Master (5e Feat)
From D&D Wiki
You have trained yourself to using your fists when wearing gauntlets to be immensely powerful, compared to others. You gain the following benefits.
- You have a +1 bonus to attack and damage rolls with gauntlets.
- When you have a free hand or hand wielding a gauntlet, you can use your reaction when being attacked to increase your armor class by 2. This effect lasts until the start of your next turn.
- You cannot be disarmed of gauntlets unless you are unconscious.
