I forgot a rule I have found quite helpful in my OSRgaming. It also works if you want to use a DCC style funnel or run L0 adventures.
Simply L0 Stacks
A L0 character has no class but they roll stats, an origin and get hit points equal to 1/2 Con modified by origin (+1 or -1 HP)
All this is retained at L1
At the GM's L0 player characters may roll their Gift and may have items appropriate to background added to the gear list.
The Return of Planescape? - Curious. There is a brief note on this 'countdown' at Enworld.
