From publisher blurb:
A little something extra for your PF2 game!
Pathfinder Second Edition brings significant change to the way spells and magic function. While the game offers many of our old favorites, there’s still significant need for an expanded spell repertoire. Specialist wizards who really want to focus on their arcane school need more options to demonstrate discipline in their field, and nobody loves their sinister secrets like necromancers do with the nine new spells here!
The new Pathfinder Second Edition has a ton of customizable options, and the Just a Second line gives you about a page of new rules content to incorporate into your campaign. A set of feats, linked spells, clever magic items, and so on. No fuss, no muss, just new ideas and mechanics for GMs and players alike!
