The Reunion DLC gives the Warrior his own set of Workouts. They can be found in chests and shops, and after winning a battle, new Workouts are given. These always require combinations of dice that need to be filled in over the course of an entire battle to complete. Once completed, the action described in the effect is done and the workout is destroyed.
One workout is selected from the list of all workouts, which is then kept throughout the match until fully completed or changed by equipment like Super Set. If completed, another workout is selected on the next turn.
Workouts are not reusable or repeatable, even if you have Re-Equip or Fury.
There are 30 workouts in the game.
