What AI agents can do with RPG Damage Engine: 4 Tools for TTRPG Combat Math

Use these tools to analyze formulas, predict encounter outcomes, and calculate final damage numbers with precision.

Calculate encounter probability

Predicts the likelihood of successfully defeating an enemy given their stats and your party's attacks.

Analyze damage expression

Provides a full statistical breakdown (min, max, average, std dev) for any complex damage formula.

Evaluate modified damage

Calculates the final damage number after applying combat modifiers like resistances or critical rules.

Parse damage expression

Takes a raw text description of damage and breaks it down into its numerical parts for analysis.

Frequently Asked Questions

How does the RPG Damage Engine calculate complex hit probabilities? +

It uses advanced simulation models to factor in multiple dice rolls and enemy defenses. You simply tell it the scenario, and it gives you a reliable percentage chance of success or failure for that encounter.

Can I use the RPG Damage Engine to check damage with different elemental resistances? +

Yes. The engine handles modifiers like resistance and vulnerability automatically. You get the final, adjusted damage number you should expect after all system rules are applied.

What kind of damage expressions can I feed into the RPG Damage Engine? +

It supports most standard TTRPG formulas, like '2d6+3 fire.' You just describe the formula in plain text, and it breaks down all the statistical properties for you.

Is this MCP better than using a separate dice calculator? +

Yes. A basic calculator only gives you random rolls. This engine calculates statistics—the average, min, max, and probability—so you get actionable data for game balance, not just a single number.

How does the RPG Damage Engine handle critical hits? +

It incorporates common critical hit rules from major TTRPG systems. You input the base damage, and it runs the calculations as if a crit occurred, giving you the right expected outcome.
