## Description

This Connector turns your AI into a high-powered math engine for tabletop RPG design. If you're tired of guessing whether a new dice mechanic is actually fair or if it just makes everyone too powerful, this tool does the heavy lifting for you. Instead of rolling a few times and hoping for the best, you can have your agent run 10,000 simulations in seconds. You can see the spread of results for heroic 4d6 versus classic 3d6 or figure out the exact probability of a player hitting a specific power threshold. It takes the guesswork out of game balance. Because it's hosted on Vinkius, you can plug this right into your existing setup and start stress-testing your homebrew rules immediately. It's about getting hard data so you can build a more balanced game for your players.

## Tools

### analyze_attribute_averages
Calculates the mean values for all attributes from your simulation results. It helps you find the true average score.

### generate_method_comparison_report
Creates a high-level summary comparing two different simulation datasets. Use it to see how different systems stack up.

### evaluate_power_threshold
Finds the probability of a character meeting or exceeding a specific power metric. It tells you how often 'overpowered' results occur.

### simulate_method
Runs a massive randomized simulation for a specific attribute generation method. It builds a large dataset of results.

## Prompt Examples

**Prompt:** 
```
Compare the average strength of heroic 4d6 vs classic 3d6.
```

**Response:** 
```
### Simulation Results: Heroic 4d6 vs. Classic 3d6

| Method | Average Strength | Standard Deviation |
| :--- | :--- | :--- |
| **Heroic 4d6** | 13.42 | 2.15 |
| **Classic 3d6** | 10.85 | 3.40 |

**Key Takeaways:**
*   **Heroic 4d6** results in a significantly higher average strength.
*   **Classic 3d6** shows a much wider spread, meaning more variety but lower consistency.
```

**Prompt:** 
```
What's the chance of getting a 16 or higher on a 3d6 roll?
```

**Response:** 
```
Based on the statistical simulation for **Classic 3d6**:

*   **Probability:** 4.2% 
*   **Frequency:** Approximately 1 in every 24 rolls.

This suggests that while a 16 is a great roll, it's rare enough to feel impactful without being common.
```

**Prompt:** 
```
Run a simulation for point buy and tell me the mean.
```

**Response:** 
```
I've completed the simulation for the **Point Buy** method across 10,000 iterations.

**Summary Statistics:**
*   **Mean Score:** 14.2
*   **Median Score:** 14.0
*   **Consistency:** High

Point buy provides a very stable baseline for character creation with minimal variance compared to dice-based methods.
```

## Capabilities

### Run large-scale simulations
Execute 10,000 randomized iterations for any specific character generation method.

### Calculate attribute averages
Get the mean score for every attribute across a massive dataset of results.

### Generate comparison reports
See a side-by-side summary of how two different generation systems stack up.

### Evaluate power thresholds
Determine the exact probability of a character reaching a specific power level.

## Use Cases

### Balancing a new homebrew mechanic
A DM wants to know if a new heroic roll makes characters too strong. They ask the agent to compare it to standard 4d6 using simulate_method.

### System design research
A creator wants to see if point buy is more consistent than standard array. They use generate_method_comparison_report to see the spread.

### Probability checking
A player wants to know the odds of getting three 16s on a 3d6 roll. The agent calculates the exact probability using evaluate_power_threshold.

### Rule validation
A designer wants to see the average strength for a new rolling mechanic. They run a simulation and get the mean via analyze_attribute_averages.

## Benefits

- Get objective data on homebrew rules by using simulate_method to run thousands of rolls instantly.
- Stop guessing about balance by using analyze_attribute_averages to see the true mean of every attribute.
- Make informed design choices with generate_method_comparison_report to see how different systems stack up.
- Identify broken builds early by using evaluate_power_threshold to check the odds of high-power results.
- Save hours of manual rolling by letting your agent handle the heavy math of statistical modeling.

## How It Works

The bottom line is you get hard data on game balance instead of just guessing.

1. Tell your agent which generation method to test, such as point buy or standard array.
2. The agent runs a massive simulation of 10,000 randomized iterations to build a dataset.
3. You get back a statistical breakdown of the mean scores and power probabilities.

## Frequently Asked Questions

**Can the D&D Character Stat Roller help me balance my homebrew?**
Yes, it allows you to run 10,000 simulations of your custom rules to see if they actually produce the results you want. You can check averages and probabilities to ensure your homebrew doesn't break the game.

**How does the D&D Character Stat Roller compare to a regular dice roller?**
A regular dice roller is for live play. This tool is for design. It runs massive batches of rolls simultaneously to give you statistical data on how a system works as a whole.

**Can I use the D&D Character Stat Roller to test point buy?**
Yes, it specifically handles point buy, standard array, and various d6 methods. You can compare them side-by-side to see which one gives your players the best experience.

**Does the D&D Character Stat Roller show probabilities?**
Yes, it can calculate the exact probability of a character reaching a specific power level. This helps you identify if certain rolls are too common or too rare.

**How many rolls does the D&D Character Stat Roller run?**
It runs 10,000 iterations by default. This large sample size ensures that the averages and probabilities you see are statistically significant and reliable for game balancing.

**What methods can I simulate?**
You can simulate `heroic_4d6`, `classic_3d6`, `point_buy`, and `standard_array` methods.

**How many simulations are performed?**
Every simulation run executes exactly 10,000 independent iterations to ensure statistical significance.

**Can I compare two different methods?**
Yes, using the `generate_method_comparison_report` tool, you can see the delta in attribute averages and success rates between datasets.
