The Barrelchest Mk II attacks with melee and ranged. It can also detect prayer, so if the player was to use Protect from Melee, then Barrelchest Mk II would start using Ranged. It also uses a special attack which knocks the player back and destroys various objects in the player's house (they are later repaired). In addition, it possesses the unique ability to drain a bit of the player's Constitution level. This means that the player's maximum life points will be lowered, and therefore the player will be unable to heal up to their original Constitution level. However, drinking a Super restore potion will restore lost levels, and subsequently allow them to heal to full health.
