The Dark energy core is a monster that appears from within the Corporeal Beast. This monster heals the Beast, and attacks any players within the vicinity of the Core. It is advised to kill the Dark Core as soon as it is launched towards the player, as it transfers the player's Hitpoints to the Corporeal Beast and in very large clans, can be quite irritating. It can be weakened immensely by poisoning it. Once it has been poisoned, its attacks will be extremely slow, although there must be at least one player around the Dark energy core or else it will start hopping around again and will attack normally. If the Dark energy core was stunned but someone moved away from him and he starts hopping around again, it cannot be stunned again. It will keep dealing damage rapidly until it is killed. If the Corporeal Beast dies, the Dark Core will disappear.
The dark core has a 1 in 8 chance of spawning after the Corporeal Beast receives 32 or more damage from a hit or when it attacks while below 1,000 Hitpoints.
