Spreadsheet for Offensive ability vs Defensive Ability, as well as crit damage returns

Hello,

I created a spreadsheet for estimating the value of OA and Crit damage, from a crit build perspective. In order for things to make sense i should give a quick introduction of how crits are rolled Grim dawn according to information from the official game guide.

Introduction:

In grim dawn the crit chance depends on your Offensive ability(OA) vs your targets Defensive ability(DA). Comparing these two values gives a single number called PTH(short for "Probability To Hit"). This PTH results in your crit chance.

Critical strikes are a bit convoluted, and depending on how large your PTH you have a chance to roll bigger crits, while still retaining the chance to roll lesser crits. Crits can roll damage multiplier values of 1.1, 1.2, 1.3, 1.4 and 1.5 before considering crit damage. There is one table with these values if you wondered what those meant, but in general just ignore them and use the "total crit%".

TLDR:

To use the tables, first compare your OA to target DA to find a PTH value using the upper table, then use the lower table to find out what that PTH value means for your damage output.

To find a target's DA:

- To find a target's you can follow the instructions under the crit damage calculator inside the spreadsheet.
- You could also use the table to estimate your PTH against the target given your listed crit chance against target, and then either use that directly or use the table to estimate how much DA the target has against your OA to get that PTH value.

However, since it messes up the sizing here is a download link for the original file where the crit stat calculator is also able to be used:

I hope it is some use to you, as it seems almost no one actually estimates the value of OA and crit damage when build theorycrafting.

Note:

The table is meant for crit builds, so the damage values will be inaccurate for PTH below 70 where your hits actually start doing less damage which i have not accounted for. Maybe i should expand it later.

Also note that the calculations are based on two assumptions i have not been able to validate yet since i for reasons won't open the game until the expansion arrives, and have had to estimate from searching the forum for information.

1. Critical damage % adds flat value to each treshhold, so if i have 50% crit damage it will turn a 1.1 crit in a 1.6 crit and a 1.4 crit into a 1.9 crit.
2. When dealing with PTH values above the final treshhold, it will simply keep adding points to the chance to get a max tier crit.

If anyone knows whether those assumptions are correct or flawed i would love to know, so please leave a message so i can correct the table.

Or if for some reason some other error is found do let me know.

I will be gone for a week and will arrive home friday, 2 days after the expansion so i can't guarantee i will correct it until after then.

Cheers!
