Merchant's Ward

An invisible magical ward appears on your head and protects you. For the duration, you have Advantage on Wisdom checks to determine lies, and any check made to determine the quality of a trade good, an object or coins. In addition, you choose up to 50 pounds of goods that you can see within 30 feet of you. For the duration, if they are moved out of that location without your permission, you can track them and know where they are. However, if the customers pay for them, or you allow them to leave with the items (for example, as a token of charity), you can't track the items.
