I’m going to write a second adventure for the Grim Hollow organized play campaign. I got a kick out of running my first at Gen Con. I’ll be running the second at Winter Fantasy

During wilderness travel in Crows, our ref @d20play.bsky.social rolls a random encounter and gets a curious elephant. It grabs a random item from a party member. The die chooses a rage potion and the beast samples it. Now we have a raging elephant problem. I like when the dice create a story

Witnessed yesterday: For some reason, a Camry driver enraged the driver in the next lane. He started pitching rubbish out at the Camry. While moving, he sticks BOTH hands out his window to do some lengthy, bird-flipping theatre with maximum flourish. Painted on his car: Responsible Driving School

When I click publish and look at my latest post, I inevitably, immediately find mistakes. In this case, I misspelled the name of the D&D franchise head. 😳

When I realized that my reaction to the D&D announcement would be ready so late, I considered scrapping the post. But in my biased opinion, I had some interesting and slightly controversial things to say. dmdavid.com/tag/wizards-...

I just checked the ticket situation at the one Chicagoland theater showing The Odyssey in 70mm IMAX. Even the 2:30am week day showings are sold out deep into September. I suppose I can wait until October.

I remember the 3e and 4e announcements. Just a big room with chairs. Now we have a spectacle with a soundtrack, a set and stars! Of course 3e had t-shirts and a Gary Gygax appearance, so that was fun

By the way, the third-level fighter I'm playing Thursday has 1 + 3 + 3 = 7 hp. He really should have followed advice and become a tailor.

Empire of the Petal Throne, TSR's 1975 D&D successor, has players reroll all their PC's hit dice at every level. When playing OSR games, I hate fragile PCs saddled with low hp through their career based on bad, early hp rolls, so I like this improvement. The vague OD&D rules even allow the method.

Just got my Gen Con judge schedule. I’m running Spies in the House of Many Eyes, the Grim Hollow adventure that I wrote, Fri, Sat, and Sun morning. Plus I have GH 2-2: Worse than the Disease on Sat afternoon. I prepped that for GameHole, but didn’t get to run it. I’m very happy with this line up!

A while back I thought about getting a phoenix mini for an adventure, so I shopped the Elder Elemental Phoenix figure. At $179, I skipped it. Now that WizKids put it on sale for $54, I splurged. I totally failed to appreciate its massive size. I’m going to need a bigger adventure.

I ran it a few times in a 4-hour convention slot. When 3 hours passed, the time came for a not-so-random encounter with the bad guy the party came to defeat. One of my favorite con mods! This photo dates to one of those games in 2016. 10 years ago. Damn

DDEX315 Szith Morcane Unbound by Robert Adducci fascinates me because although it’s an Adventurers League mod, its design targets home play with a big open dungeon complete with random encounters.

This is what I wrote for now. _Tactics._ If any characters are Frightened, then the [creatures] favor their melee attacks over more uses of _Fear._ This keeps the encounter from becoming a tedious series of Wisdom saves.

DM David Hartlage @dmdavid.com · 13/06/2026
As I write an adventure for organized play, I have a question for DMs: The party faces 3-4 monsters with the ability to cast fear 3 times each. Are you spamming fear because that's the way to "win," or are you using it more sparingly, say once per turn.

Is DnD 5e too lenient? Almost boring? Usually yes. But these Sithicus Ashes of the Black Rose adventures are HUMBLING me. Watch me and @dmdavid.com run from DM @d20play.bsky.social and try to survive!

Anecdote from Bulgarian tour guide: My son, he says to me, “We don’t get old anymore; we just level up.” I know that’s via video games, but it still has me thinking about the reach of Dave & Gary’s creation.

Players formed teams and played the same adventure. The highest-scoring teams advanced through rounds of competition. The A1-4 Slavers adventures come from the multiple rounds of a 1980 D&D tournament. For a sense of the scoring, look at the TOURNAMENT SCORING page in Hidden Shrine of Tamoachan.
