Dungeoneering/Hard mode

Hard Mode is a Dungeoneering feature that was released 10 September 2013. It can be obtained as a reward after completing the elite set of Daemonheim tasks. It is only available for complexity 6 dungeons and makes the dungeon as difficult as it can randomly be.

How to access Hard Mode
To start Hard Mode, and assuming the player has met the above requirements, and has selected the floor and appropriate complexity, start a floor. Upon clicking the ladder, the player is prompted with, "Activate Hard Mode?"--once you select Yes, the player is prompted with a size. It is strongly recommended to choose size Small.

Once inside, do the dungeon as normal. However, keep the differences listed below in mind.

Upon completion of a Hard Mode floor, the following message will appear in your chatbox: ''You have completed floor [number] on Hard Mode. Your lowest floor incomplete on hard mode is: [number].''

Someone who has completed the elite set can allow people who have not, access to hard mode. This requires the player with the task-set complete to form and lead the dungeon.

Differences with Hard Mode

 * At the top left, under the Current keys section, "Hard Mode!" is written
 * All monsters and bosses spawn at their maximum levels. This includes the boss.
 * Due to the high combat level, certain boss monsters are difficult and may take a few minutes to kill, as opposed to a normal floor. This can be extremely tediuous if doing a solo-floor. Bosses begin to have special abilties. For example, World-gorger Shukarhazh begins to heal if no players are in its room.
 * A party of 3 or more may experience more monsters per room.
 * The chance of encountering slayer monsters is drastically increased.
 * Multiple slayer monsters may be encountered in a single room
 * The chance of finding tier 8+ items throughout the floors is increased
 * All doors behave like guardian doors, regardless of what kind of door it is. The "guardian eye" above the door will not appear. This means, you cannot exit any room without teleporting out of it. If you attempt open or leave a room, you will receive the following message: The door won't unlock until all the guardians in the room have been slain.
 * In regards to teleporting, you can teleport out of the faux-guardian doors and dead-ends, but you cannot teleport out of boss rooms.
 * All skill doors and challenge rooms will require skills of level 90 or higher, even if doing so makes the dungeon impossible to complete.
 * The "90" doors are crucial doors; this means that this door will be on a criticial path or lead to a critical path. Any doors higher than 90, speficially pot doors, do not need to be completed.
 * If you lack any 90+ skills, it is recommended to bring a friend who is close to 90+ or is 90+
 * Keep in mind that you are able to boost to these doors.
 * For example, a Gatherer's potion will boost Divination if you need 90.
 * The chances of getting Tier 10 and Tier 11 items as boss-drops is extremely high.
 * Doors that require boosted stats over 99 (portents or potions) become increasingly common.
 * Food is scarcer.

Rewards
After completeing the 60 Floors of Daemonheim in Hard Mode, players are rewarded with a title: "of Daemonheim". This title is also a requirement of the Trimmed Completitionist cape.

To even get this title, the highest requirement for it is 119 Dungeoneering.

Trivia

 * While not officially stated, each player needs 90 in each skill to complete the dungeons
 * It does not matter the order in which you complete Hard-Mode.
 * You can start on Floor 60 and work your way backwards, for example. The chatbox will display that your highest floor complete is 60, and your lowest incomplete is 1.
 * In theory, all players with 119 Dungeoneering can get this title
 * But, this is assuming that they have access to the Hard Mode or tags along with someone who does
 * Because players are able to experience more slayer monsters than normal, the drop-rate of their specialised drops become increasingly common
 * For example, it is entirely possible to see two Edimmu in a single room along with a Soulgazer
 * The rules of basic Dungeoneering apply to Hard-Mode; keeping that in mind, you are able to go about the floor as if it were a normal floor
 * The increased monster level does not have an effect on certain rooms (presently):
 * Suspicious grooves
 * Ghost Room
 * Monolith (sometimes; varies on the amount of people in the party)
 * Mercenary leader (sometimes; varies on the amount of people in the party)
 * While monsters have been given a significant boost in terms of their level of difficulty, boostable doors remain the same
