Penance Rangers are only encountered during the Barbarian Assaultminigame. Like Penance Fighters, they can only be killed by the team's Attacker or by the use of the egg launchers. The attack style required to damage them changes over time; It is the job of the Collector to tell the Attacker which stance to use. Their combat level raises with every wave, and starts of with 69 and at wave 10 it lowers again.
If the Attacker uses the incorrect stance, they take 100 points of unblockable damage, heal them, and will be penalised at the end of the wave.
In hard mode, these monsters gain an adrenaline bar, which slowly fills up as they attack players. When the bar fills completely, they use the ultimate abilityDeadshot, which causes a large initial hit and extra damage over time. The damage over time can be cleared by using the Freedom ability.
In the Barbarian Assault hall, there is a statue and a plaque that describes them. It says: 'The Penance Ranger - These creatures store a highly corrosive liquid in the abdomen at the base of their bodies. It is believed that thsi was initially used for breaking up food matter to be passed on to the Queen for digestion. With the increase of easily digestible food sources (e.g. 'daring' adventurers), this functionality has been removed. It now seems to be used for offensive means in the form of projectiles. The only way to defeat this monster is to confront it with brute force, as it has no convenient weakness. That being said, the Penance Ranger can anticipate and adapt to attacks using the telekinesis common between all Penance, and hence, when taking on this monster, it is important to change attack style periodically to perform damage.'
