Negotiator

You have honed the knack of the deal and counter offer, perhaps by crossing words with creatures used to getting the upper hand in negotiations. You gain the following benefits:

• Increase your Charisma score by 1 to a maximum of 20.
• When you attempt to convince a creature to engage in a course of action or to change its attitude with a Charisma (Persuasion) check and fail, you can retry the check on your next turn with disadvantage.
• When you purchase a good or service, you can attempt an opposed Charisma (Persuasion) check versus the seller's Wisdom (Insight). If you win the contest, you secure a 10% discount on the transaction. Once you use this feature on a given individual, you can't use it on them again for one week.
• When you pay for lifestyle expenses during downtime, they are halved.
