Homebrew 2d10 vs 1d20

[DEFCON 1]

I also did 2d10 for ability checks in my two CoS games in order to get the bell curve and make the modifiers have a little more impact on results. (Kept the d20 for combat just due to ease of use and for the criticals on Nat 20s).

After going with the 2d10 for a long time, we came to the conclusion that in practice it didn't really make any appreciable difference. For ability checks the characters succeeded on them sometimes and failed them sometimes. And the checks occurred with such frequency that no one could really notice if the percentages changed on how often they succeeded via 2d10 vs 1d20. After a while it all just came out in the wash.

So now I just use 1d20 again for all checks.

I was unable to choose between them, so I compromised with a 1d15+1d5.

If I implemented this, I would look hard at the various ways PCs can achieve extreme AC values (greater than 22). I would consider +n shields, armor + shield spell, heavy armor + cloak of displacement. Otherwise, chance to hit them drops from 5-10% to 1-3%.

This also ties in to the decisions of, what is an automatic hit? What is an automatic miss?

In one of the games that my group ran, we did 2d10 for skill checks while also using the alternate proficiency dice rule (instead of a fixed proficiency bonus). A lot of the players enjoyed rolling more dice and feeling as though there was more variability to the outcome. I honestly can't say whether or not it made much difference, but it seemed more fun.

We had talked about possibly upgrading or decreasing dice size as a way to have more granularity with advantage and disadvantage (similar to Genesys,) but we never got around to trying it.
