OKAY! SO there are three things that were updated.
First is SD5. I put in a bunch of other new magical items that I'd been procrastinating on doing, so that's new.
SD16 is a race builder tool, and a new archetype that Boots build and I compiled and edited and all that jazz, so thank him for that.
And I added the new variant rule in SD16 to Rules and Ammo. So there. Go download.
