Teamwork: At 4th, 8th, 12th, and 16th level the party may decide to take a teamwork feat and vote upon which one they will take. This feat will apply to every character in the party regardless of when they join or whatever feats they may already have. Taking this feat does not replace the ability score improvement or fear the players may gain at this level.
Swap!: Once initiative has been rolled but before the enemies initiative has been revealed two party members may agree to swap initiative, only 2 players may do this once per combat. If more than 2 players wish to swap then it will be voted upon by the party.
I'll follow your lead!: Once initiative has been rolled and revealed, any party member may choose to lower their initiative to 1 below any other party member in the combat. Your initiative score can not increase in this way, it can only be reduced. You cannot use this feature if Swap! has already been used.
