Leatherworker

You have mastered the art of working with leather and hide, and can use such materials to reinforce armor. You gain the following benefits:

• Increase your Dexterity or Wisdom score by 1, to a maximum of 20.
• You gain proficiency with leatherworker's tools. If you are already proficient with them, you add double your proficiency bonus to checks you make with them.
• When you craft a nonmagical item using leatherworker's tools, it requires half the amount of materials and time to craft.
• With 10 minutes of work, you can reinforce armor with leather or hide, giving it the ability to lessen a terrible blow. To use this benefit, you must have leatherworker's tools with you, and the armor must be within reach. When the armor's wearer is hit by an attack, they can expend the improvement to gain resistance to any bludgeoning, piercing, and slashing damage dealt by that attack. You must finish a short or long rest before you can improve armor again, and any armor you have modified lose this improvement when you finish a long rest.
