David (5e Equipment)
From D&D Wiki
Wondrous Item, artifact (requires attunement)
A small, unseemly pocket handkerchief
David This item is sentient, once attuned, the personality of a mild-mannered man named David will join you in your body. He will only take control when he deems it necessary - like to talk with you, or apologize for your behavior. He loves tea parties. He is also very frugal, and will try to prevent you from making needless purchases.
As part of being with David, you are under these effects:
All intimidation and deception checks are treated as if you rolled a 1, as David interjects
When you need to be polite or are at a formal event, you may ask David to take over. While David is interacting with others, you have advantage on all CHA checks (except deception and intimidation), and your CHA becomes 22.
David is very perceptive - Your passive investigation, perception, and insight all become 20, and you automatically pass any of those checks with a DC lower than 15, as David will move your eyes for you.
Due to his love of tea, David will take over your body entirely when fine tea is nearby, and go over to try some. You can resist this each time with a DC25 WIS save. On a success, David will not try again for that specific tea for 12 hours.
