Age of Sigmar Statshammer

A tool for calculating and comparing damage outputs for Warhammer Age of Sigmar units (also referred to as Mathhammer).

The production deploy of the tool is located at: https://aos-statshammer.netlify.app/

The tool works by adding a number of weapon profiles to various units, which can contain a number of modifiers (abilities)

Features

• Average Damage Stats
  • Gather the average damage that each unit is expected to do against each possible save.
  • This average is a calculated value (not simulated)
  • The average damage is presented the following forms:
    • Table
    • Bar Graph
    • Line Graph
    • Radar Graph
• Profile Modifiers
  • Add various modifiers, or abilities, to your weapon profiles in order to replicate the vast array of unit rules/abilities.
  • Some examples are:
    • 'Deal x Mortal Wounds on a roll of y'
    • 'Rerolls'
    • 'Leader Bonuses'
• Target Modifiers
  • Add various modifiers, or abilities, to the target to which stats are generated against (the opponents unit).
  • Some examples are:
    • 'Ethereal'
    • 'Rerolls'
    • 'Negate wounds and mortal wounds on a roll of y'
• Simulations
  • Generating x simulations to gather the following:
    • Discrete Probabilities
    • Cumulative Probabilities
    • Various Sample Metrics (mean, max, variance, etc.).
  • The number of simulations is customizable from the simulations screen.
• Import/Export JSON
  • Save your crafted units so that you can re-import them later
• Export PDF
  • Export the full stats, as well as, simulations to PDF form
• Dark Theme
• Persisitent data between refreshes
• And more
  • Keep an eye on the Github Releases

Roadmap Features

• Ability to add modifiers to the unit as a whole, and not just to each profile
• Ability to provide points costs to provide stats for average damage / 100 points
