You are a true master of your craft, pushing the boundaries of creativity and expertise. You gain the following benefits:

1. Masterful Craftsmanship: When you spend a long rest working with your artisan's tools, you can choose one item you are proficient in crafting. The time and cost required to craft the chosen item are halved.

2. Quick Repair: As an action, you can attempt to repair a damaged object, such as a weapon or a piece of armor, using your artisan's tools. Make a Dexterity check with proficiency in the tools. The DC is determined by the DM based on the complexity of the repair. On a success, the object is repaired, and its effectiveness is restored. The DC for this check is 10 + the item's rarity.

3. Artisan's Insight: You gain advantage on Intelligence (History) checks related to the origin, craftsmanship, or historical significance of objects, artifacts, or structures.

4. Mastery in Diversity: Choose one additional proficiency from the following options: a set of artisan's tools, a language, or a skill. This represents your broad expertise beyond your primary craft.
