Pathfinder Remaster GM Core

Pathfinder GM Core releases this November 15 at your favorite local game store, bookstore, and the Paizo Store along with Pathfinder Player Core. As part of the Pathfinder Second Edition Remaster Project, it offers a fresh entry point to the Pathfinder Second Edition roleplaying game for Game Masters!

Customization and support are at the foundation of Pathfinder, and this book provides you with numerous ways to customize your game. Select whatever parts you need for the game you’re running with the toolbox nature of GM Core.

This blog will guide you in navigating the chapters of the GM Core, just like a trusty wayfinder! If you’re brand new to tabletop roleplaying games, read our summary on Archives of Nethys.


Introduction

The focus of every Pathfinder game is the player characters—they’re the stars of the show and appear in every scene that plays out in-game. But what about those scenes? What stories are being told? What old legends are being discovered, and what new ones are being forged? Who are the villains, the allies, the traitors, the lovers, the monsters, and the gods? Who runs the world? When you’re the Game Master, that’s all up to you!
GM Core

Here you will find the basics of what it means to be a GM and guidance from the authors on how to use the book. They help you choose your tools whether you are a new GM, running a published adventure, making your own, or just need items.


Running the Game

As Game Master, you run each session of Pathfinder, providing the link between the players and the world of the game. It’s up to you to set the scene as the player characters battle monsters, interact with other people, and explore new locations.
— GM Core

This chapter provides tools to create a welcoming environment, prepare adventures, create characters, and plan and run sessions. You will find one of the best guides in the industry on special considerations, running encounters, exploration, downtime, difficulty classes, and rewards. You will also find sidebars on topics such as Tools for Responsible Play, Collaboration During Play, and more!


Building Games

Game Mastering can be an extremely creative endeavor, and this chapter gives you a suite of tools to make your own campaign or adventure. You can even create your own creatures, hazards, and items to populate your game, or even make your own game world!
— GM Core

This chapter covers everything you need to build an adventure of your own, from campaign structure to encounter design, world building, variant rules, and more. While you may need to make something from scratch, you can also adapt existing material using the guidance from this chapter. Build your own hazards, items, and creatures using GM Core’s in-depth developer advice and mathematical benchmarks. The Rewards section gives you all you need to distribute Experience Points, Hero Points, and treasure throughout your campaign.


Age of Lost Omens

Ten thousand years ago, the world of Golarion came close to ending. Earthfall, as this extinction-level event came to be known, saw the world pummeled by a shower of falling stars that sank continents, hollowed out new seas, and destroyed civilizations. It took centuries for the world to recover, and centuries more for society to rebuild, but recover it did.
— GM Core

Though the Building Games chapter includes everything you need to create your game world, the Age of Lost Omens is a fully developed setting that’s ready to use and has vast amounts of support across Paizo’s adventures and Lost Omens books. Explore the Inner Sea Region and beyond, learning about the rich cultures, religions, and factions therein. Use tools like nation and settlement stat blocks to understand our locations or flesh out your own realms. This chapter also covers extraplanar setting elements, taking your campaign into the Great Beyond.


Subsystems

When your game goes into uncharted territory or you want to emphasize an element of gameplay that usually gets overlooked or condensed into a single check, you can use a subsystem. As the name implies, subsystems are extensions of the main rules system that allow you to explore a particular topic or style of play at your table.
— GM Core

Part of Pathfinder’s robust game engine lies in its ability to explore elements of gameplay that are not always in the forefront. The Subsystems chapter gives Game Masters a diverse set of tools to tackle any in-game challenge and to track progress on tasks using Victory Points. Where some systems may leave you in the lurch wondering “what should my players roll for this?”, Pathfinder’s subsystems provide support for Game Masters and players alike. Subsystems covered in this chapter include Influence, Research, Infiltration, Dueling, and more.

Treasure Trove

Characters acquire treasure from the glittering hoards of their foes, as rewards for defending the innocent, and as favors from the grand personalities they treat with. As they progress through their adventures and improve their station in the world, characters collect ever more fabulous items, from enchanted armor and weapons to spell-infused wands and staves.
— GM Core

The Treasure Trove is a Game Master’s guide of alchemical and magical items and how to use them. Not only does this chapter cover a large range of treasure—ranging from potions and magical staves to apex items and more—but it’s also a comprehensive guide to reading item stat blocks and understanding how items work.

Finally, GM Core is complete with Treasure Table, Glossary, and Index sections as additional tools for you to use on the fly.

Inside GM Core you’ll find the guidance you need to build and run the fantastic stories you wish to tell!

Interesting choice to describe the chapter on "Running the Game" twice.

edit: OP has fixed this, so I'm editing this so I don't look dumb.

The foxhead medallion grants complete immunity to all magical effects, right?

I had REALLY hoped that when paizo said editing and clarity was going to be a focus that they'd improve their layout... but alas... a split table in the preview.

I guess no one in the non-indie ttrpg space has seen the layout from games like OSE??

I know I've got an Old School Essentials PDF lying around here somewhere so I can back you up, but my file organization is abysmal.

Still, the layout here--split table be damned--isn't so bad when you factor out that massive gutter in the middle. I was about to really go off on all the wasted space in that big beige box when I suddenly remembered how book spines work, lol.

Just spells tagged with four of the elements and also spirit damage. ;)

Yeah, you always have to remember, when looking at these in PDF format or as previews like this, that there are first and foremost designed to be massive hardcover books. You need to have a *little* lead in for the binding. :V

Hm. Seems like Authorization Day will be Thursday October 26th, and the shipping window will be October 30th to November 10th. I'm guessing, of course. We'll see. :-)

It's changed here, but not on the main post.

Unfortunately it is also magical, so you become immune to that effect and the medallion no longer grants you protection. /s

Hmm. It seems that the Madcap Top will fill the niche opened up by the removal of the OGL Deck of Many Things.


I really liked having the "Age of Lost Omens" lore available from the start as a player, though I can see why it felt better suited to the GM core than the Player Core since not all players will use it.

Is there/will there be a good, short introduction to the world online or in a PDF for new players playing in the Golarion setting? The wiki is a bit overwhelming to start with.

Probably way too late, but they didn't give us a playtest or earlier preview, sooo...
Suggested Variant Rule : Key ability scores are added to cantrip damage.

Honestly, simple rule that would solve most of the discontent about caster changes. Without it being in the book, it won't get into the Foundry rules, which is how I imagine most people play online.

Foundry doesn't need any extra automation to support that - if you open the details for a spell, there's just a tickbox indicating whether ability modifier is added to damage. Add your cantrips, tick the box for each, and you're done.

I don't think this sort of selective buff fits within the space of variant rules, especially when it undermines the various design goals laid out by Adam. It would be like adding a variant rule that reload weapons no longer take an action. House rules and official variant rules cover very different ground.

TBH, if this is the only complaint we have left about the editing, layout and clarity, I will be beyond ecstatic.

TBT I feel it is like asking PF2 to bring back the PF1 feeling of powerful casters by removing the Incapacitation trait : happiness for a few for the meager price of annihilating the efforts the designers did to bring us a better balanced game.

Only for magic affecting you directly. Indirect uses of magic, like someone chucking some manure at you or walking through an already existent magical portal are not canceled by the fox head medallion. It does have a cool interaction with creatures that have an antimagic field, though, so be sure to bash one of them with it.

Are... are you guys making Wheel of Time references?

Holy crap you guys are making Wheel of Time reference.

I love you. <3

(Although clearly the medallion only functions against casters who identify as female [except randomly in the last session of the campaign the GM may decide to ignore that restriction])

Yes the Player Core has a short section about what players know about the Lost Omens setting. The GM Core has the larger section.

What? No, that's an artifact.

This is the Rod of Wonder for minor whacky random stuff.


Now I come to think of it, Karzoug was on the cover of First Edition Gamemastery Guide, and Alaznist was on the cover of the Second Edition Gamemastery Guide. Xanderghul is on the cover of Pathfinder Remaster GM Core. If this is a tradition, then I wonder which runelord would be the cover model for Third or Fourth Edition Gamemastery Guide.

Anyway, Karzoug was with a blue dragon and Alaznist was with a black dragon. I'm honestly not sure which dragon is with Xanderghulhul. It does not look like one of the true dragons.

We're easing off the chromatics a bit here in ORCland, but iirc that one is supposed to be a Mirage dragon, one of the Arcane variety of dragons.

The GM Core dragon is the Mirage Dragon. The Player Core dragon is the Diabolic Dragon. The Monster Core dragon is the Adamantine Dragon.
