Kharidian scorpion
Three rare Kharidian scorpions feature in the Scorpion Catcher quest. One is deep in Taverley Dungeon, one is in the agility training course at the Barbarian Outpost, and one is upstairs in the Monastery. Players can catch the scorpions during the Scorpion Catcher quest by using a scorpion cage on them.
These scorpions have not been seen anywhere in the Kharidian Desert or any other locations in RuneScape, so they are possibly very rare.
A player will receive 30 damage while attempting to "pick up" the scorpions, it is possible to have 3 damage "splats" on the player at a time from repetitive clicking. Please note that this can be fatal to characters with a low number of lifepoints. It is rumoured that some players have died because of lag, as they have attempted to pick one up at moderately low lifepoints under lag not aware that they deal out 30 life points at a time. Some players also use them as a form of suicide when they have low lifepoints or are in need of stat healing.
