[RPG] Aid or Interfere roll+Bond… How much variation is there with bond bonuses

New answer for a renewed question. The old one is here

I'd say that a hidden move is quite against the grain of *World games'idea of moves. It robs the players of their agency in determining their characters' story.

And in your case, the intra-party conflict that may occur if the infiltrator is exposed seems to be more important than whether the infiltrator will be able to commit acts of sabotage and betrayal behind their backs. I'd base the move on that and add another move for the other party members to respond.

Infiltrator

You are an agent of your deity with a secret agenda. When you commit acts of sabotage and betrayal behind your comrades' backs, mark experience, and choose one comrade that doesn't already have it to receive the "Suspicious" move immediately.

Suspicious

You are suspicious of the infiltrator's weird behavior. When the Infiltrator commits acts of sabotage and betrayal behind your back, roll+INT.

• On a 10+, you have seen enough, but just need some more evidence. Replace this move with "Deeply Suspicious"
• On a 7-9, you noticed something unusual. Take +1 forward to your next "Suspicious" roll, but getting there wasn't easy. Choose one:
  • You had to get into trouble to get your information and come back with 1d8 damage.
  • Information is pricey. You had to spend 2d6x20 coin to find some clues.
  • Lies are everywhere. You wrongly implicate another comrade (The infiltrator will tell you who). You cannot aid or interfere with them until the next time you roll "suspicious"

Deeply suspicious

Replaces Suspicious

Same as "Suspicious" but add these to the list of possible outcomes.

• On a 12+ , you have enough evidence to expose and implicate the Infiltrator. Now everyone in the party knows better. You decide the fate of the traitor.
• On a 10-11, you collect a solid piece of evidence, slowly building a strong case. Give another comrade the "Suspicious" move if they don't already have it, or replace their "Suspicious" with "Deeply suspicious"

This is based on the assumption that the infiltrator is a well known and trusted member of the party in the beginning. The first act of the infiltrator is essentially free. His or her comrades suspect nothing in the beginning and they trust the infiltrator. But then it gets harder and riskier every time.

And yes, all this can and will eventually leave the fate of the infiltrator in the hands of another player. The question is, when?

You've got the petition backwards. Petitions are the things the cleric does to worship, not what the cleric gets from worshipping.

Your religion is cultish and insular, add Petition: Gaining Secrets

Petitioning by Gaining Secrets means learning a new secret for the cult, not being given one by the god. To petition What Lies Beneath via Gaining Secrets, the cleric needs to learn a secret for What Lies Beneath. This cannot be spammed, because it's limited by what the cleric can personally uncover in the world. One new secret discovered on their own = one new chance to use Divine Guidance to learn something else.

How it works is like this:

1. Adventure and investigate the world, and while doing so discover a secret unknown to the god/cult.
2. Discovering that secret gives the cleric an opportunity to petition What Lies Beneath — the god is pleased because they've uncovered a new secret for them.
3. Trigger Divine Guidance to learn something different the god already knows.

What you've been doing instead though is:

1. Ask for secret from the god via Divine Guidance.
2. Get it.

… which would be inherently spammable. And that's why the move doesn't work that way.
