The Patchwork Scroll is a print collection of four small (originally) PDF expansions for Exalted. All share the trait of being “leftover material” from their respective main books, material that was actually pretty good but did not within the page count limit. Releasing it as PDFs, and now, later, as a print compilation, was a nice move. Especially so since there is a lot of fun stuff here, I’ve used quite a few bits and pieces from this in my own game. Nothing you absolutely need, but a pile of extra options for martial arts, Wyld creatures and encounters, Dragon Kings and ghosts.
The first supplement is The Imperfect Lotus, containing some extra martial arts styles (left over from Scroll of the Monk). Many are quite specific to certain regions, but can provide fun flavor. There’s also a weird set of MA for gods, based on the Virtues.
Splinters of the Wyld is next, providing some extra Wyld locations (and creatures), leftovers from the main Wyld book. Lots of good stuff here, I ended up using quite a few of these when my players were off in the Wyld. High weirdness factor, which suits the Wyld perfectly.
Debris of the Fallen Races contains some martial arts styles for Dragon Kings, some Chaos Pattern Charms, and some extra subterranean creatures. Useful if you have Dragon Kings or the Underfolk in your games, useless if not.
Lastly, Lost Arts of the Dead has some extra Arcanoi for ghosts. May or may not be useful, depends on the game.
Each of these can also be purchased separately as PDFs, of course.
