I was thinking back to D&D 4e and one of the things I liked about it were the ability cards. It made it easy to keep track of what you could do throughout an adventure. So, I decided to bring this feature back to D&D 5e! Attached is a PDF you can print out double-sided. The cards are each standard poker size. The fronts say when you can use it, what type of action it is, and have a space to write in a short description of the thing you can do, while the backs tell you when you get the action back.
I hope you all enjoy! :)
