A blue egg is used in Barbarian Assault to hurt penance monsters. If loaded into the egg launcher and shot at penance creatures, it would have different effects depending on the type of creature. It will lower the stats of Penance Fighters and Penance Rangers, extend the poison affecting penance healers, and makes the next food item act as the correct bait for penance runners.
As players may intentionally use the wrong bait or repeatedly poison penance healers to death quickly instead of waiting for the poison to whittle down their life points, Penance Fighters and Rangers would be good targets as they are less situational; targeting them would reduce the load of healing especially if the attacker has a low combat level.
