D&D 5E Stamina Rules
Below is my take on using the mechanics from Stamina Lite and the Stamina TTRPG and using them for Dungeons and Dragons 5th Edition. Making these was a bit of a meta activity for me since the mechanics introduced were originally designed to be homebrew rules for 5th Edition, but I had long since decided to make a fully separate RPG instead before I decided to go back and make these as a way to (in my opinion) make 5th Edition better, probably especially at high level play.
These rules are completely untested, so while I have confidence that the general concept is storng and valid, it is possible that some of the numbers balancing may need to be redone (I may even do it myself in the future).
