The VOIDRUNNER'S CODEX is coming! Explore new worlds, fight oppressive empires, fend off fearsome aliens, and wield deadly psionics with this comprehensive boxed set expansion for 5E and A5E!
What flavor needs to be preserved and is ruined by things existing in it? Cause that is the question. Greyhawk is literally the original Kitchen Sink setting. Everything in the D&D books were assumed to exist there.
Yes it's going to be smaller and less fleshed out than the settings that got around 200 page books, but it's still going to be a whole chapter of the book so I would expect at least 30 pages.
The Challenge Rating for each monster will be the same. So a CR 12 monster is still going to be CR 12, but they are all being rebalanced to more accurately match those CRs.
I should mention as well, that Fizban's used a couple images of the new dragon designs as well.
The New Green and White were also used on Diceling Toys
