Is this the WOTC print, or an actual wood/white/oce?
The game is specifically and explicitly made to be modified and expanded. It does, indeed, say so in the rules; validating some things I have seen old-school gamers say.Oh the days of “I’ll start downloading this file and go to sleep.”
I also splurged on the premium re-release of a few years ago. Would love to give it a run for a couple of adventures, but there’s no way my group would go for it. Heck, 1d6 damage for all weapons alone would be enough to send them running.
