Crushers become available after completing the map Besik Farms. While not as durable as a Freedman, the Crusher deals more damage and can stun a target for one turn.
1 Spirit Point
Crushers deal 50% less damage while stunning their victims, so use it to incapacitate key enemies in an encounter while the rest of your team deals damage. Upon dying they will grant your other units additional armor - though the effect is the same as with the Freedman and the Crusher requires more expensive resources to craft.
