From the publisher blurb:
"D&D -> Thief/Rogue, Revised (2016)
Back in the '80s I wrote the BECM version/edition of the D&D game. The span of 36 character levels was a requirement. When I spread the thief abilities over that range, it was a huge mistake, because hardly anybody played higher than Level 12.
So I've revised it, added new stuff, made it lots more playable and interesting. And I've gone with "Rogue" as a title, because 'thief' is too limiting. (Jack-of-all-Trades, or Factotum, would be even better.)
If you like, give it a download at Piazza (link below) and use that message board to tell me what still needs fixing."
