This MCP server provides deterministic calculations for weapon banner mechanics. Use calculate_probability to find the chance of a target weapon appearing on the next 5-star pull, calculate_expected_investment to estimate the remaining pulls and primogem costs, and validate_banner_state to verify if your current pity and fate points are valid. It helps players plan their resource spending for specific target weapons.

I have 50 pity pulls and 0 fate points. How many primogems do I need to guarantee my weapon?

You will need 6400 primogems to guarantee your target weapon.

What is my probability of getting the weapon if I have 1 fate point?

Your probability of getting the target weapon on the next 5-star pull is 0.75.

Is it possible to have 95 pity pulls?

No, the maximum hard pity threshold is 90 pulls.

You can use the `validate_banner_state` tool to check if your current pity pulls (0-90) and fate points (0-2) are logically possible.
