The Synergist's Codex is a collection of new character options and GM mechanics to facilitate tactical team-based play.
Four new subclasses each incorporate a unique take on teamwork based mechanics. The Strategy Domain Cleric uses battle strategies to guide their allies, the Choreography dances a highly mobile duet across the battlefield with their allies, the Field Medic Fighter* tends to the wounds of the fallen in the midst of a battlefield, and the Tether Master Wizard creates arcane bonds which bolster allies or hamper enemies.
Four new magical items can be granted as rewards to parties which show great teamwork, or perhaps used as a light suggestion by Game Masters who would like to see more cooperation amongst their players.
Finally, our new Ally Action mechanic can be used by Game Masters to grant their players new tactical options while simplifying the complication of large encounters for themselves. When parties recruit allied NPCs to their side, these new actions substitute for the NPCs turns in combat, giving your players greater control of their side and reducing the number of creatures you need to track!
