Intimidation. Intimidation vs. Insight (+1d6 on success, -1d6 on fail and one NPCs disposition worsens)

Fake "Tell". Deception or Performance vs. Insight (gain +1d6 on success or -1d6 on fail. Also one NPCs disposition worsens)

Throw off. (reroll a die and take the lower value, improve one NPCs disposition)

Risk.

Shenanigans may have earned you some enemies.

After three wins or getting caught cheaing word gets around and nobody will play with you.
