Dreadnaut

Dreadnaut is a boss monster that was first mentioned in Postbag from the Heim. This boss requires level 95 dungeoneering to access. His name is quite similar to that of a Rammernaut. His main attack style is melee, and he also uses a special attack that looks similar to the dragon scimitar's and can disable your protection prayers or deflect curses for 5 seconds.

From what it seems, Dreadnaut is a warped form of a Rammernaut. This has been proven from the brutes that he kills before you enter the room. He stops charging at you, which is strange since he is still a Rammernaut. He could also drop Equipment requisition orders like Rammernaut.

It is possible to safe spot Dreadnaut if you wish to use magic (or ranged), which is especially useful as he is weak to magic (ranged is not recommended). To do this, you should drop the group gatestone outside the boss door, and with your minimap facing the door. Enter the boss room, hugging the wall, go east, and drop a gate in the corner by the barrel. After dropping your gate, teleport to the group gatestone and wait for Dreadnaut to come up towards the door. Once he is there, teleport to your personal gate, leaving the group gatestone outside for emergencies and proceed to kill him with magic (or ranged). He will be unable to move as he is trapped by the boxes, and therefore will not deal you any damage, he is also unable to spawn the little "orange blobs" which deal you damage, so you should be able to defeat him without taking any damage. If you're with a team, make sure all your team drops a personal gate inside before luring.

Trivia

 * The examine text seems to indicate that the Dreadnaut is under the mind-control of a stalker, similar to the way sea slugs control minds.
 * The name of Dreadnaut's music track is spelled Dreadnaught.
 * After reading his lore, one may infer that Dreadnaut is in fact Rammernaut Hoskins, being posted to the warped floors and as a result of this he has been warped and driven insane.
 * In rare occurances before fighting Dreadnaut, there are a couple Brutes standing nearby trying to talk to him. Both Brutes talk back and forth saying that something isn't right, before Rammernaut decides to kill them.
