Sway

When you SWAY, you influence someone with guile, charm, or logic. You might outright lie to someone’s face. You might persuade a sucker to believe you. You might argue the facts with an officer. You could try to trick people into affection or obedience (but CONSORT or COMMAND might be better).
GM QUESTIONS

• Who do you SWAY? What kind of leverage do you have here?
• What do you hope they’ll do?
• Are you lying?

When you SWAY someone, you aren’t invested in their thoughts or feelings. You’re manipulating them—either with charm, lies, or arguments that can’t be easily dismissed. You’re trying to get them to do what you want, whether or not they want or need it. You can SWAY a friend or contact—they’re probably vulnerable to you—but the risks are higher if they figure out what you’re doing to them; it might be a desperate thing to try.
Additionally, SWAYING someone isn’t mind control. You need some reason for the target to listen to you. That could just be because you’re charming or desirable, or it might be good evidence and solid reasoning that backs up your story. Which approach works best depends on the target and circumstance. What works on one person might not on another. If you don’t have any leverage, you can try fear or intimidation with COMMAND, or genuine connection with CONSORT or DOCTOR.
It’s not possible to use SWAY when the target won’t listen to you. No amount of fast talk will convince the pirates whose ship you boarded that you fell in through an airlock by accident. If you need to convince someone that you’re someone you’re not for a moment, look at the Mystic’s Psy-Dancing ability.
You might be able to SWAY another character. Ask the player if they have some reason they could be SWAYED by you—perhaps you’re the captain and it’s your ship, or they owe you a favor. If you don’t have anything, you won’t be able to convince them.
