I was looking for a list of which abilities recharge on a short rest versus a long rest, and I couldn't find any. So I made one! Here it is, for all you DMs with rest balance issues:
Ability Meta-Table
I hope this helps! Any feedback would be appreciated, even (constructively) negative ones. I know that this doesn't include things like hit dice and abilities that recharge for everyone, I didn't think it was necessary. If you want me to add it, just ask. Also, I think some of these might be "at the end of a short/long rest" instead of "once per short/long rest," but I'm not sure. If someone with more rules mastery than me wants to go through and find things like that, feel free. The way I wrote the Uses column is that "ability" means that the exact number of uses is calculated based on an ability score, and therefore varies from character to character, and ∞ means infinite uses. I included these for things like the Barbarian and Druid capstone abilities, so that DMs don't forget that they can ignore those abilities at some point. Enjoy!
