I've just started DMing for my little brother, he's 11 but really smart for his age, he grasps the game the more we play, I do most of the rolls for him though.. He has 4 characters and he's running through Scourge of the Howling Horde right now, I'm working on a custom adventure right now for level 3-4 characters that I'll run him through. Anyways I wanted to know if anyone can tell me some DM tricks to keep the table exciting and fast-paced, I remember playing at my local comic shop going a lot faster so how can i speed things up?
I really appreciate any other DM tips and tricks to enhance the tabletop experience!
