Rules from 5e For use in OSR Games

Originally published June 24th 2024

In 5e HD is determined by size. Tiny is 1d4, small 1d6, medium 1d8, large 1d10, huge 1d12, and gargantuan is 1d20. I think that works wells.

For those unaware of what those categories include here is a plain english explanation.

Tiny = Garden gnome

Small = 5 year old

Medium = Adult

Large = Horse

Huge = Elephant

Gargantuan = Orca

This is all.
