A simple command line utility for finding probabilities for Charges, Casting and Dispelling in Warhammer: Age of Sigmar.
2d6 has a basic interface best demonstrated via examples:
What is the probability of landing a 9" charge?
$ ./2d6 9
27.78% (exact: 5/18)... with rerolls?
$ ./2d6 9 r
47.84% (exact: 155/324)... and, say, a +3 to charge?
$ ./2d6 9 r +3
92.28% (exact: 299/324)What's the chance of successfully casting a spell with casting value of 8, with rerolls, +2 to cast and assuming the opponent can dispell me?
$./2d6 8 r +2 d
81.93% (exact: 6371/7776)If you find r and d to terse, you can replace them with reroll and dispell as you see fit.
You can also mix and match ordering and abbrevations. For example,
$ ./2d6 10 dispell +2 reroll
63.65% (exact: 9899/15552)is equivalent to
$ ./2d6 10 r +2 d
63.65% (exact: 9899/15552)Negative modifiers are also obviously supported:
What is the probability of completing a 9" charge with -2 to charge?
$ ./2d6 9 -2
8.33% (exact: 1/12)All you need is a python 3 runtime. There are no dependencies.
You invoke the command by running ./2d6 or python3 twodeesix.py.
There are some unit tests in tests.py. Also, a crude monte carlo
simulation to sanity-check the tool is found in verify_montecarlo.py.
- Add support for modifiers on Dispell attempts.
- Add support for rerolling Dispell attempts.
- Add support for Lord of Change's Mastery of Magic
