Duradel

Duradel is the second highest level Slayer Master, and the father of Kuradal. Players must have at least level 50 in the Slayer skill and 100 combat before they may receive Slayer assignments from him. Duradel is found upstairs from the fishing shop in Shilo Village. To have him assign you a task, players must have completed the Shilo Village quest.

Duradel used to be the toughest slayer master. However, on 8 December, 2009, a new slayer master was released. It was Duradel's daughter, Kuradal. She is a tougher slayer master, as she requires 75 slayer and 110 combat. The Slayer skillcape was moved from Duradel to Kuradal.

Once the player has completed the quest Smoking Kills, they are rewarded with 15 Slayer reward points for completing a task assigned by Duradel, assuming that they haven't switched tasks with Turael. This makes Duradel the second most rewarding in terms of reward points. He also gives 75 points for every 10th task, and 225 points for every 50th task completed for a total of 1125 points per 50 tasks.

Assignments
NOTE: Slayer masters assign higher-levelled monsters more frequently if the player's combat level is high.

Slayer Challenge
After a player has performed several slayer tasks for Duradel, he will occasionally offer a special task in place of a regular slayer task. The player can decline to take the special task without penalty. If the player accepts the special task, completing the task:
 * Earns extra slayer experience.
 * Earns Slayer reward points, if the player has completed the Smoking Kills quest.
 * Counts as a task for the player's consecutive task count, which is used for slayer reward points.

Duradel's special task is for the player to slay monsters in the Slayer Tower in a single trip without leaving the tower. The numbers of monsters that must be slain are:
 * 21 Crawling Hands on the ground floor
 * 8 Banshees on the ground floor (requires protection from the banshees' screams)
 * 9 Infernal Mages on the first floor
 * 7 Bloodvelds on the first floor
 * 7 Aberrant spectres on the first floor (requires protection from the spectres' odour)
 * 5 Gargoyles on the second floor (requires a Rock hammer)
 * 6 Nechryaels on the second floor
 * 6 Abyssal demons on the second floor

As the player kills the required number of each set of monster, a notice appears in the chatbox that the player has killed enough of the monster for the challenge.

Note that level 85 slayer is needed for this task (for the abyssal demons), the player needs special equipment against some monsters, and the player needs to be prepared to defend against melee, magical melee, and magic attacks. No monster attacks with more than one attack style, so switching between melee and magic defence armour as needed will be an effective tactic.

The reward for completing this task is a bonus of 20,000 Slayer experience and 35 bonus Slayer Points (bringing the total for the task to 50).

Tasks
To complete the hard Karamja Tasks you have to ask Duradel for a slayer assignment.

In While Guthix Sleeps
He has a small role in the quest While Guthix Sleeps as one of eight warriors recruited to hunt Lucien. After his recruitment during the quest, Lapalok replaces him in Shilo Village as the second highest-level Slayer master.

Upon questioning him in the White Knight's Castle as he prepares for his fight, he reveals he was being kept in Shilo Village by an unknown higher authority, and required special permission from them (he seemed to communicate telepathically with them) to leave for his part in the quest. Apparently, he took several shortcuts and 'trod on very important toes', as he puts it, to become the greatest Slayer master (which he was at the time, before being surpassed by his daughter, Kuradal). Unfortunately, he will not reveal any more information to the player, and states that he will take this secret to the grave to avoid tempting others. He does just that. The group attempt to save the player from Lucien in the Wilderness, and Duradel is one of the six who perish in the ensuing battle.

Also after this quest, a statue of Duradel is fittingly placed next to a statue of Turael at the entrance to the Slayer Tower near Canifis, and another statue can be found around the lake in Falador Park along with the other 5 heroes. During the cutscene of the battle between the heroes and Lucien in While Guthix Sleeps, it is revealed that Duradel has a combat level of 197.

Trivia

 * On his statue at the Slayer Tower and the Falador Park he is wearing the slayer cape.
 * He wears a pair of Rune Claws and a Cape of Legends.
 * It is possible to ask him why a powerful slayer master like himself would only wear Rune Claws, when doing so he will tell the player that he owns a stronger pair, but only uses it when the need arises.
 * In While Guthix Sleeps he seems to be wearing Dharok's platelegs and Guthan's platebody. He also used to wear his Slayer cape, until it was fixed by Jagex on 13 May 2010.
 * It's possible his name is a reference to the sword Durendal which belonged to paladin Roland in the Medieval story.
 * When asked about Vannaka, Duradel said "My student Vannaka may be strong and well armed, but what use is that when by your first swing you've already been stabbed in the back by a lightning fast creature? Besides, rune claws are just the ones I wear for teaching, I've got a special set few have ever seen back at my house for when I really mean business. Vannaka knows this and wouldn't ever want to challenge me - again." . It is revealed that Vannaka was a student of Duradel's, and once challenged him to be the strongest slayer master only to be beaten by his master with a sort of rare and powerful weapon. This may also mean that he has a set of Dragon claws, despite not having used them during the battle in While Guthix Sleeps.
 * Duradel used to sell the Slayer cape, before the release of Kuradal on 8 December 2009.
 * On the day of the release of While Guthix Sleeps, some Slayer masters, including Duradel, had a glitch in their names in the chatbox. If a player was assigned a task and asked "Got any tips for me?", instead of Duradel or Lapalok the game showed slayer_master_5_multi. This glitch could not be seen if using an Enchanted gem, Slayer ring or the NPC Contact spell. It could only be seen if talking personally to Duradel or Lapalok.
 * Duradel is a member of the Legend's guild.
 * If you use an enchanted gem and you are level 100+ and have 65-74 slayer and have no slayer task, you will talk to Duradel even with the exception of completing While Guthix Sleeps. Just activate the gem and ask "Got any tips for me?" They will say "I am not your approved Slayer Master; I'll pass you over to someone more suitable.
 * Duradel appears to be wearing the same facial paint as the Jungle Savages in the Kharazi Jungle, possibly indicating that he was originally from there.
