From publisher blurb:
Teamwork traits are a subset of social traits that reflect your working relationship with your comrades; how you encourage them, lead them, follow them, or your bond and friendship with them. Sometimes they benefit, sometimes you benefit, and sometimes you both benefit.
Enclosed herein, are 11 teamwork traits for your PFRPG compatible game world. Traits such as "Bait and Tactics", let you feint an enemy, allowing your other allies with this trait to also consider that enemy flat footed. While "Follow My Lead" allows one ally to follow directly behind you over difficult terrain without penalty.
"Working Together makes the Work go Faster" nets you and an ally a bit more gold per week on your Profession Skill checks.
Be "Jealous of Your Rival" or have a "Competitive Friendship". It's your team, and everyone has different traits.
