Edwin Greloff's fourth map is a quest item in The Witcher 3: Wild Hunt that can be purchased from Éibhear Hattori (after completing Of Swords and Dumplings).
Reading it reveals the locations for:
- All standard Griffin armor diagrams at Dragonslayer's Grotto
- Mastercrafted Griffin armor, steel sword, and silver sword diagrams

- [addendum] Map ain't worth shit. Only thing I found were some griffin symbols scratched on the walls. Can see we're not going to get anything worth near enough to pay back the debts that dandy doctor wracked[sic] up with us. Good thing he's worm food now. But maybe it would be worthwhile to loot that tomb under Crookback Hills? I doubt our doctor friend would've wasted his time just running around looking for primitive drawings - there's gotta be some treasure about.
