Am playing my first campaign and feel behind the others who either have experience with D&D or video games so know the jargon and flow of the sessions. This book helped me with much of that jargon - what’s a saving throw - so I feel better prepared. I only skimmed the DM section but noticed there’s no conclusion. The book just ends. If the authour ever updates it, please add a glossary at the front or back of 25 most used terms in a session and campaign. I play in a few days. My Tiefling Bard is ready to sing and charm.
