This is my collection of d20 house rules. They've changed a lot over the years. Originally, they were more drastic, including variants from Unearthed Arcana, Pathfinder, and True20, as well as a number of custom mechanics. More recently, I've pared it all back to mostly just tweaks and clarifications.

Rules I'm beta testing or still considering are in grey. Everything is OGL, so take what you find useful.
