Here is the link to download cpyke's MathHammer Calculator v1.1. You will need Microsoft Excel, or another program that can read .xlsx files. So far it can calculate probabilities for shooting infantry and vehicles, as well as assaulting infantry and vehicles. It also has a deep strike risk calculator which definitely helps in placing your deep strikers. I will be adding more features to this as I go such as rending, daemon weapons, and template weapons as well as improving what I have now. And if you think of something that should be added, or see something that is wrong let me know and I'll try to add it in later versions.
Example: Which close combat weapon should I use?
In honor of the newly released codex, my example will be Chaos Space Marines fighting the forces of the Imperium.
The purple boxes show your chances of hitting, wounding, and getting through the enemy's armour. The red box shows the number of wounds you can expect to make on average. And the final, and maybe one of the most useful bits of information that this gives is the kill point ratio. Basically this number is how many points are you spending to wound the enemy. So if this number is 1.0, then for every point your model costs, you are killing 1 of theirs.
There are a few limitations that should be noted. First is that initiative is not taken into account here. So the axe and power fist have a chance of getting killed before they even hit. There is a way to figure the effect that initiative has, but it would be a bit more complicated and you would have to know exactly what enemy you will be fighting, and what weapons they will be using. Since this calculator is for list building, and not determining the outcomes of battles I left that out. Also if you are going up against a multi-wound character then using a power fist to get an insta-kill could be much more cost effective than the axe. It really just depends on what you are trying to accomplish.
I was planning to add all of my examples in one post, but I underestimated how long it would be. So be watching for the next post in this series where we will look at the best choice for anti-air in a Chaos army. Thanks for reading, and any comments are greatly appreciated!
