*💰 The haggler's helm 💰*

This helm has an angular shape with gems and coins welded to the sides. It is made entirely of gold and silver, which was used to display status. This helm is sentient and has the personality of a greedy goblin (LE) and as an action, the player can choose to bargain with it. The player either tells the helm what punishment they will impose on themselves, or the reward they want in return. The player must roll persuasion and then, depending on the result, the DM chooses what the helm replies with. If they chose their punishment then they get a random mechanical reward (e.g advantage on attacks) and if they chose the reward then they get a random mechanical disadvantage (e.g disadvantage on saving throws). The player cannot back out once they have chosen to bargain and effects last until the end of a combat encounter or for 1 hour unless specified in the terms of the bargain (DM decides).
