System Mastery

No but thankfully this outfit really exists for the Halloween for grownups Dragoncon

We know you've got a choice in heroes this Halloween. Thanks for going Gold.

Guy's really leading the charge in inspiring new Bad Religion songs.

Oh also I know it's an annoying ask but if you do buy it anywhere we could really use a few reviews. They're super important to the process!

We've got a new book dropping today! It's the second edition of our Dungeonmeister cocktail book, now with mocktails and a bunch of new recipes! A perfect gift for anyone that consumes fluids.

Well everything else is awful but at least the left has reclaimed frog imagery.

SUMMON NEW ELDER GODS NYCC Panel and Signing featuring James D'Amato, Jef Aldrich, and Jon Taylor Saturday, October 11th 11:00 AM 1E Comm Stage Book signing at 12 PM, Hall 1A Tables 39-48

I totally forgot the bananas panel we are doing at NYCC this year.

To fit the horror theme for the show, @systemmastery.bsky.social @gurglespasm.bsky.social and I are going to do a Worldbuilding panel where we create new elder gods and then perform a ritual to summon one.

Taking a seven year old on any walk is the exact same experience as an old MMO escort quest. They walk painfully slowly and every fifteen seconds you realize you lost sight of them because they pathed into an enemy encampment (stall that sells $27 bubble wands).

At the very end they say drivethru RPG is handling printing and all so that's the best we know.

Hi everyone! Sorry the episode was late! Jef (me!) has been going through a lot of family stuff recently and it's been tough, but hey, who isn't going through tough stuff right now, right? Anyway, I'm posting the episodes again here tonight, and I'm gonna try harder to keep doing that later, too.

You should really have us on to play it some time. One of us would be happy to run it. It's good shit.

Yes, dude. Absolutely. Sentinels. I could talk about it forever and intend to.

Here's an Amazon link! It'll be out in time for holiday gift giving! a.co/d/0ASRqCp

Wild that we wrote a book that did well enough they let us make another edition of it but here we are. Dungeonmeister Expanded! Available for preorder wherever books are sold, releasing September 28! A whole new chapter of alcohol-free recipes and several more new drinks besides!

Oh I figured it was because Disney was hungry for 2014 to be the year that Tumblr was just millions of Elsa recolors with different elemental power sets, like fire, or ...fox.

Due to unexpected technical difficulties, this week's System Mastery episode is currently delayed. I expect it to go live next week some time. Thanks! Sorry!

Hell yeah! More books coming out everyone! That new version of the Dungeonmeister cocktail guide is gonna be rad! We've got mocktails in there now!

The day is finally here! Please go support Cosmic Century Knights, Homecoming, and Chuck on kickstarter!

If you back both CCK and Homecoming you'll recieve Chuck for free, it's such a great deal.

Help us grow from hopeful adventurers into legenday heroes!

Oh and of course there's some of our books in there!

And you know? I've gotta give it up to the old standbys I may not listen to all the time but ALWAYS have what I need - Jef & Jon at @systemmastery.bsky.social. That podcast is a literal treasure trove of content for all kinds of systems, but especially ones that never held the public eye for long.

Oh absolutely. Back from GenCon and all. Love to see you at Darrington, that's fantastic! Say hi to Darcy for us, we love her(who doesn't).

Oh hey, I just put a lot of pieces together real fast! Anyhow you're welcome, it was a fascinating read. I just hope you didn't get to the bonus content, because I'm sure we played it absolutely wrong.

Good, I hope it gets more airplay so I can get it at the karaoke place.

That's what I'm here for!
