Tests

A choice can require a stat test:

{
  "text": "Force the door open",
  "next": "force_door",
  "test": {
    "stat": "strength",
    "difficulty": 9
  }
}

Formula

2d6 + stat_value >= difficulty

The engine rolls two six-sided dice, adds the selected stat, and compares the result with the difficulty.

Suggested difficulties

Difficulty	Meaning
7	Easy
9	Medium
12	Hard or nearly impossible

You can use any integer difficulty your story needs.

Failure nodes

On failure, the engine automatically looks for a node named after the target with a _fail suffix:

target node:  force_door
failure node: force_door_fail

Always create the failure node:

{
  "force_door_fail": {
    "text": "You push with all your strength, but the door does not move. You hurt your shoulder.",
    "choices": [
      {
        "text": "Enter through the gap",
        "next": "entrance",
        "effects": {
          "health": -1
        }
      }
    ]
  }
}

If the _fail node is missing, the engine has nowhere to go after a failed test.

Valid stats

Use the stat IDs defined by the engine:

• strength
• dexterity
• intelligence

See Stats and Perks for their meaning.
