The Arkus has an ability that I am deciding to call "The Poster's Wish".
After engaging a creature in conversation for at least a minute, you can attempt to influence how that creature is perceived, promoting it as a friend, dismissing it as a fool, or denouncing it as an enemy. Your words are so well chosen that even you and it are affected, because your conviction and its doubt are paramount. The accuracy of your assessment isn’t important as long as you keep up the rhetoric. From then on (or until you change your rhetoric or the creature offers a convincing defense to those who’ve heard your label), the friend’s social interactions gain an asset, the fool’s social interactions are hindered, or the enemy’s defenses are hindered. Action to initiate, one minute to complete.
