Penance Runner

Penance Runners are monsters encountered during the Barbarian Assault minigame. They have no combat level, do not attack, and cannot be attacked directly. However, they must be killed before they reach the cave on the other side of the battlefield, or the Defender will lose points.

To do this, the Defender must lure the runners into traps, with baits (such as tofu, crackers or worms). At the traps, if the Runner says Blurghh, this means that the wrong bait has been placed, and the trap has failed. And if the Runner says Chomp chomp, this means that the Runner has taken as bait, and the trap will go off, which will kill it immediately. Runners can also be damaged, stunned, or poisoned with eggs fired from the Egg launcher. When using the launcher to kill Penance runners, red eggs are the most useful to fire since they can deal 35 life points each, thus killing the runner in two hits.

Trivia

 * The Penance Runner resembles the Flood Carrier organism from the Halo series. There are other monsters in RuneScape that resemble aliens of the Flood.
 * The Runner's legs resemble those of player-character's legs before the graphical update. The stance and shape are exactly the same.
