Before attempting to fight the beast, you must be aware that if you die you will not receive a gravestone. Your items will instead be dropped on the floor and after 3.5 minutes, they will be visible to any other players. After an additional 1 minute, they will disappear completely. Secondly, any weapon other than a spear will deal only 50% damage to the beast and therefore it is highly recommended to use a Chaotic spear or Zamorakian spear to fight it. Furthermore, Summoning familiars should not be used as they will be devoured by the beast and partially heal it.
The beast uses three main Magic-based attacks and these are:
- Standard Attack: The beast will fire a blast of energy at you which is capable of hitting up to 4500. This damage can be partially reduced with Protect from/Deflect Magic, but the reduction is less than the normal 50%.
- Stat Drain Attack: The beast will fire what looks like a white orb at a player which drains either their Magic, Summoning or Prayer and deals damage when it hits. If the stat has already been drained to 0, then it will deal extra damage.
- Area-of-effect Attack: The beast will fire what looks like a claw into the ground in front of it's target, which then explodes into small orbs which spread out across the ground and hit up to 400-600 each. This can be avoided by moving one square away before the attack hits.
