Info:
This is the skill of talking others into doing things against their better judgment.
It is not taught (intentionally, that is) in school; you study it by working as a salesman, confidence man, lawyer, etc. In any situation that calls for a reaction roll, you may make
an Influence roll against Fast-Talk instead.
If you have Fast-Talk at level 20 or better, you get +2 on all reaction rolls where you’re allowed to talk!
Note that Fast-Talk differs from Acting. In general, Fast-Talk is used to get someone to make a snap decision in your favor, while Acting is used for long-term dissimulation
