Blacksmith

You are a master blacksmith, able to more easily create powerful weapons and armor. You gain the following benefits: :

• Increase your Strength or Constitution score by 1, to a maximum of 20.
• You gain proficiency with smith'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 smith's tools, it requires half the amount of materials and time to craft.
• With 10 minutes of work, you can temporarily improve a melee weapon's balance or sharpness, giving it the ability to deal fierce damage when needed the most. To use this benefit, you must have smith's tools with you, and the weapon must be within reach. When this weapon deals damage, its wielder can expend the improvement to roll one of the weapon's damage dice an additional time and add it as extra damage of the weapon's damage type. You must finish a short or long rest before you can improve a weapon again, and any weapons you have modified lose this improvement when you finish a long rest.
