From publisher blurb:
Unleash your Pathfinder RPG! Returning for another installment, our fan-favorite Everyman Unchained line takes aspects of the Pathfinder RPG and adjusts them to enhance their playability and fun! Each Everyman Unchained product includes a small tidbit describing the design decisions made, so you’ll always know whether each Everyman Unchained product is right for you and your table.
This installment of Everyman Unchained includes: a complete revamp of the teamwork feats mechanic. Now if you possess a teamwork feat, you gain the ability to establish a team of allies that benefit from it. No longer will you have to worry about trying to coerce allies into “buying in” on teamwork feats with you or rely on tricky class features or archetype abilities, several of which have had their powers adjusted within this product.
