The Sigil
Mr. 3000 (Words per post)
Made my first WotC purchase in nearly two years this weekend with the advent of UA. The OGC declaration is something to the following effect (not verbatim, but this is pretty close):die_kluge said:Let me first caveat this by stating that I do not own UA, but would like to do so.
But, IIRC, UA was not going to be 100% OGC, but a big chunk of it is. That said, did you, in fact, verify that this particular part of UA is open content?
The OGL specifically prohibits XP advancement tables.
Product Identity: All trademarks, logos, proper names (of characters, places, etc.), and the terms beholder, gauth, githyanki/githzerai... (insert "special PI D&D monsters pulled/culled from the SRD but that do appear in the MM here")... and illustrations/artwork/graphic and desing elements are designated as product identity.
Open Game Content: Except for the beholder, gauth, githyanki/githzerai bloodlines which appear in Chapter One and that called out as PI above, the entire contents of this work are Open Game Content.
A very well-worded and pretty darn clear OGC statement, and one that puts the entire text of the book except for the stuff relating to "iconic monsters" into the OGC canon.
Because of that OGC statement, I did something I haven't done in years... bought a WotC book.
