So, if I’m undstanding this, while making death saving throws, the player can every themselves by taking levels of exhaustion. 1 level for Bonus action or reactions, 3 levels for actions. They can move half their movement speed (while staying prone?), as well as talk, without taking additional levels.

Additionally, you’re reworking the exhaustion rules to be -1 to all ability checks and saves per level of exhaustion, up to 10 where the PC dies.

Then the first short rest improves exhaustion by y one level, then they have to use long rests, which improve 2 levels each.

Sound right? I think this sound a pretty decent

The OGL only covers what’s in the SRD, which is essentially the Basic Rules you find in the starter set plus a bit more.

Also worth noting after the fiasco earlier this year the SRD is also published under Creative Commons.

The full rulebooks aren’t covered under any open license, and the only way to (legally) publish things with content from those books is to do so via DMsGuild where a portion of sales goes to royalties, unless you get some kind of an exclusive license (which generally doesn’t happen).

Pathfinder is different, in that they made all the rulebooks open licensed, so something like Archives of Nethys completely legit, so long as they don’t use artwork or specific IP.

(This is all a very loose, oversimplification of the whole situation, and I’m aware of that. Rules/mechanica cant be copywriten, only the specific expression of them, yada yada.)
