Things I am learning as a first time DM
The first 10/15 minutes are the worst. Everyone’s attention is on me and I have to talk?!!! However once the first bit of session is over the players go and do the things, and then it’s a bit easier after that
Dungeons.Make sure there’s a couple things per room minimum, like an encounter and loot, or world lore and a puzzle, or some kind of mixture of things. Keeps different player types engaged with variety.
Playing a story heavy campaign and want the players to engage the story? Fuck with their backstories. One of my players has a connection to the Bad Guy the party followed from a bar because the bar got blown up. During looting of the place they followed him to another player found photos of themselves and their siblings. Things are gonna happen.
Don’t be afraid to fudge rolls and dcs depending on rolls and things. Sometimes things need to be changed on the fly. The dice gods are fickle beings.
Improv is hard. But a necessary skill. Hopefully I will get better in time lol
Describe the places in detail, and NPCs with only a couple distinguishing features.
Oh god do prep before the day you play. Unless you can handle that type of thing.
