On one claw, the Harbinger Ranger archetype reflects what the Dark Crests were designed to do: infiltrate and destroy other broods from within. On the other, they are not allowed to become furies due to anger management training
, nor does their Adapted Pheromones trait say that they may choose to succumb to the frenzy as the Long Claw can. They are not susceptible to Ss'ressen frenzy, and the pheromone-producing gland that triggers it in others was removed, but does this mean that someone specially trained to hunt other broods would be physically unable to do so?
