This goes out to all your probability nuts out there


Pathfinder First Edition General Discussion


So awhile back I was looking at creating a Gnome Hunter, and was wonder just how much of a hit I was talking by not going with something like human which would get a bump to strength, rather than a penalty. I looked around for a good A/B DPR calculator that would let me get a sense of the impact and couldn’t find one, so I built my own Pathfinder Probability:

http://fieldofbattlecards.com/dmg_calc/index.html

Hello World and welcome to Probability Pathfinder! This application is designed to calculate the Damage Per Round (DPR) of a protagonist or antagonist in the Pathfinder Role Playing game (or any other game that uses the "3.5" d20 game system). It has some important features that make it different from the typical DPR method:

1. Probability Pathfinder is not designed to simply calculate the average DPR using the standard formula (h(d+s)+tchd). Instead it calculates the percentage likelihood of EVERY possible outcome in a round. This data is then plotted onto a histogram as well as being summed into a single average. The hope is by being able to "see" the probabilities behind the average will help players better understand the basic probabilities behind the game...or maybe I'm just a math nerd and no one else cares.

2. This application is designed for multiple attacker profiles at once, giving you the ability to smoothly and easily compare multiple different builds against one another. For instance if you wanted to compare a 6th level, 18-19 strength, power attacking fighter using an unenchanted Great Sword, Great Axe and Falchion, this tool will let you do that on one screen.

3. The data on this application is built for sharing. While no data is stored in the application itself, as you type data into the form a URL at the top of the page will dynamically change to reflect the form. Anyone who visits that URL will be shown the exact same data you just typed in; perfect for any internet arguments you want to have.


Looks good. Here are my ideas:

1) Clarify what you expect for input. I was Wondering if I put in dice formulas or what.

2) this doesn't cover two weapon fighting, rapid shot, multishot, etc


It takes standard dice input (xdy where x is number of dice and y is the number of sides) for all of the damage sections. You can also add, subtract, multiple or divide by dice or whole numbers.

It does handles two weapon fighting by clicking "Add Attack." For example this link compares a long sword / short sword combo (with weapon focus on the long sword) vs two short swords (with weapon focus on both) The long sword short sword demonstrates multiple different attacks.

Rapid shot can be done by manipulating iterative attacks, and multishot can be done by just increasing the damage in the damage box (1d8+4+1d8+4).

For more information on how it actually works, just click on About / Help (though, embarrassingly I did forget to mention adding attacks or creating new profiles, I'll do that as soon as I get home)
