Bulwark beast

The Bulwark beast is a Dungeoneering boss. At the beginning of the encounter, it has armour plating which nullifies any damage received from melee or ranged. The armour must be broken using a pickaxe before it can be damaged. It attacks with all three styles, including melee (crush), ranged (falling rocks, green breath attack) and mage (electrical attack). Magic attacks, deflect prayers and familiars will hit through the beast's armour regardless and damage its life points. It is best to fight the Bulwark beast with melee armour and Protect from magic as the melee armour provides the best protection against the other two styles. He is weak to slash attacks.

This boss does randomly drain Prayer.

His own attack where he drops rocks weakens his armour as well. This takes a long time and is not recommended as he can easily kill you as you wait.

Trivia

 * The method of using a pickaxe to fight a Bulwark beast is similar to fighting the TokTz-Ket-Dill (monster) in the Tzhaar quest TokTz-Ket-Dill.
 * It is possible to kill it through magic without breaking the plates. Familiars will also directly damage the beast whether the armour is broken or not.
 * It is also possible to kill it without using a pickaxe or magic; Occasionally rocks will fall from the ceiling, which will damage both you and its armour plates.
 * The Bulwark Beast is almost identical to the Gluttonous behemoth, except for the colour, armouring and shield-like mandibles, due to being a member of the same species (as mentioned in the Behemoth notes.) Stomp (monster) is also of the same species, but is too large to fit through the portal.
 * It is possible to fight the Bulwark beast with a Dungeoneering level of 23 (the required level is 24).
 * It is possible to get a different pickaxe then what is said in the chat box. (EX: You received a Kratonite Pickaxe, when you really get a bathus)
