Sage Advice is on Facebook.
There are daily Dungeons and Dragons Questions&Answers on rules and dungeon mastering but It’s different from this website because there are also news and tips from D&D world not only focused on 5e, plus we discuss Questions&Answers of DnD Designers tweets.
I’ve added some revised images that comes from ancient fantasy novels, personal insights and I’ll try to answer you about rules of the best game ever made.
Hope to see you there!
