Out of the Abyss
Persuading, Debating, Interrogating
This system will be used to govern success or failure of the party when trying to convince another NPC to provide information or perform a task. Note that this encounter system is only needed when that NPC is opposed to the request
Each individual in the party can take one of the following actions each round.
(1) Making an argument or counter-argument allows the player character to make progress towards convincing the target to provide information or perform an action OR undermine the progress of an adversary.
Successfully delivering the argument depends on Charisma (Persuasion), Charisma (Deception) or Charisma (Persuasion).
Progress towards successful persuasion depends on the type of argument. Logical ones use Intelligence, Intelligence (Arcana), Intelligence (Nature), Intelligence (Religion) or Intelligence (History). Emotional pleas use Wisdom or Wisdom (Insight). Note that the argument must reference some relevant citation if using a specific skill (i.e. to use Intelligence (Nature), the argument must be based on some logic about nature).
(2) Identify objections or read intent allows the player character to identify the target’s objections OR identify an adversary's ultimate intent. Success is dependent on Wisdom (Insight).
(3) Aiding an ally makes the target more receptive to arguments or bolsters an ally’s arguments. There are two options when using this action. (1) The player can choose to aid one ally, which requires no roll and grants advantage to one party member. (2) The player can choose to aid the entire party, granting all of them advantage, laying the groundwork for a series of arguments by successfully rolling a Intelligence, Intelligence (Arcana), Intelligence (Nature), Intelligence (Religion), Intelligence (History), Wisdom or Wisdom (Insight). Note that the action must reference some relevant citation if using a specific skill (i.e. to use Intelligence (Nature), the aid must be based on some argument about nature).
(4) Distracting an adversary flusters an opponent’s attempts to make arguments. Success means the adversary makes arguments at disadvantage. The same options that are available for aiding an ally are available here.
(5) Casting a spell offers a variety of advantages in social encounters.
