Thanks!My first advice: listen to Morrus. He's been doing this for a while so he knows what he's doing.
My second advice: The relevant part here is, I think, section 15 of the OGL. This is where you list both your own book, as well as any source you're incorporating OGC from. Note that you need to include the full section 15 of any source you use. For example, let's say I want to publish a book that includes the Beer domain from Midgard Heroes Handbook. If I do, I have to include all of this in section 15 in my own book:
And then I add my own product, something like: Staffan's Big Adventure © 2021 something something.
And the Beer domain doesn't really have anything to do with "Deep Magic: Elven High Magic", but I still need to include that in my section 15, because it's listed in the source I took the Beer domain from.
Also, did you notice what isn't on the list above? D&D. D&D is not open content. Wizards of the Coast has released a System Reference Document which is open content, and which mirrors much of what is in the core books, but they are not the same. If you want to publish stuff, you would do well to leave your books somewhere out of reach and rely on what's in the SRD. You don't want to accidentally include a wizard who can cast Bigby's hand and get a nastygram from Hasbro's lawyers.
Neither of those apply to publishing for Level Up. The OGL is the correct route to take for this particular topic.Not sure if the other two ways to publish D&D material are relevant and would be really interested to know:
It looks like the Fan Content Policy can be used for works that also include material from the OGL, so Option 1 may be possible? If so, would be great. I currently make use of it for the Tome of Variance project - the next edition is coming out September and I was then hoping to align it with A5E (not least as my own groups will change over!).
- Via the WotC Fan Content Policy, if you're publishing for free (I see some donation/ads allowed). Game mechanics are a confusing issue since game rules are by definition not copyright/IP.
- Or via DMs Guild (not recommended: policy not available for link but needs a close read as it doesn't let you distribute your copyright anywhere else even for free; also would need to be very careful not to include any A5E copyright).
Man. I hate that thing. It's apparently what you get pointed to if you ask about making stuff for 4e. The game with a license that exists but not in the place the license says it does but allegedly still applies despite not being made available. The "naughty word around and find out" license >:|
