Looking through the Additional Resources list recently, I noticed that there's some allowed equipment in AP 9: Escape from Old Korvosa. Among that is the urumi, a weapon so ridiculous I decided I had to build a character who used one. Or better, two.
In discussing things with some of the local GMs, however, I was told that the urumi had been changed in one of the later books, and that the new version no longer had reach, amongst other changes. We assumed that characters are required to use the newer version, though I couldn't find any specific ruling to this affect. Most likely explanation is that this is just a glitch: AP 9 is old, and possibly out of print, and thus it's possible that whoever's updating the Additional Resources list didn't even realize what was in it.
So, two things:
1. Where more than one version of an item (or feat, spell, what have you) exists, is there a general ruling on which one is legal and which one isn't? We assumed the newer one is required, but I'd like to be sure.
2. You may want to take a look at AP 9 the next time the Additional Resources list is updated. It's possible that all of the weapons there have since been revised.
