Pulsework Soldier is one of the most resilient enemies found in the Vile Peaks, resisting all types of attacks. They lose these resistances when staggered, and also lose their ability to attack, making defeating them once staggered trivial.
Pulsework Soldiers are often targeted by the roaming CocoonWatchdrones and Thexterons. Choosing the right side when engaging these warring groups is important, as taking down Pulsework Soldiers is often tedious.
