Advice book on how to convert/modify the Pathfinder Roleplaying Game ruleset from high-magic (and how!) to function in a low-magic game.
I am not familiar with this book I will have to pick up the PDF and check it out.Green Ronin's Psychic's Handbook.
Adventures different from what Paizo is offering.
Give us something special (megadungeons or fantastic locations) and/or site-based adventures. Give me planar sites I can drop into a campaign (like a pit fiend's lair in Hell or the abode of a minor demon lord in the Abyss). Heck, give me planar and non-planar ruins (small and large) or dungeons that I can drop into a campaign.
We do have Coliseum Mopheuon in PDF and in Full-Color print (via our print distribution partner Cubicle Seven) at your FLGS or at places like Paizo.com. Its Planer (plane of dreams) and as a transitional plane like the plane of shadow, astral, and ethereal its easy to drop into any campaign.
We do have fantastic location with out Evocative City Sites series, but I have been thinking about a fantastical 5 room dungeon setting.
Nothing. I've got a decade worth of 3.x material that is very easy to use in Pathfinder. I used to be all about the 3pp material but these days I'm not seeing a need or have a desire for any of it anymore. I keep reading about different versions of the same things and it has really burnt me out on it.
