Just a simple DM aid that I quickly cooked up with Excel: Sheets of 144 pre-rolled hit point totals for 1 HD monsters. Gross.
Since we use d6 hit dice in our homebrew game, I made sheets for both 1d8 and 1d6:
With circles to mark off as they get hit.
I have a pile of d6s that I roll and just line up while playing, but this might be a useful alternative. I don’t have nearly enough d8s to do the same thing with d8 HD (and they don’t line up nearly so nice) so this could be a big time saver.
Also going onto the free Kreations page. I’ll cook up more sheets for higher HD as time allows.
