Vannaka (formerly called the combat instructor on Tutorial Island) is a medium-level Slayer master in RuneScape and used to be Duradel's student. Vannaka is also one of the NPCs associated with the Varrock Tasks. His mastery in swordsmanship and combat is shown by his high combat level of 146, strength level of 112, and the fact that he wields both a steel two-handed sword and dragon square shield at the same time. According to Duradel, another Slayer Master, Vannaka was once a student of his, and does not wish to challenge him due to his master's great skill.
He instructed new players in fighting with a shortsword/wooden shield and a bow back when Tutorial Island was still accessible.
K'ril Tsutsaroth is classified as a greater demon; thus, killing him counts towards any greater demon Slayer Task, and also allows a player to take advantage of the abilities of a black mask or Slayer helmet, if they have a greater demon Slayer task. Players will earn 350.5 Slayer experience if they slay K'ril Tsutsaroth on their greater demon slayer task. Before 31 December, K'ril Tsutsaroth was classified as a lesser demon.
NOTE: Slayer masters assign higher-levelled monsters more frequently if the player's combat level is high.
After a player has performed several slayer tasks for Vannaka, 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:
Both adult and baby chromatic dragons can drop scales. Multiple scales of the same type of dragon can be obtained, but extras are destroyed when the task is complete. These scales are only available as drops when the player is on this special task. Note that the challenge is only complete when the scales are brought to Vannaka; simply collecting all four scales does not finish the task.
Postbag from the Hedge 20 revealed that Vannaka was Duradel's student and had lost while attempting to challenge his master.
In issue 27 of the God Letters, it is revealed that at one point, before he went into exile on tutorial island, Vannaka was a follower of Saradomin. Saradomin states "It is somewhat of a pity that his glory days are behind him, and his self-imposed exile to tutorial island is in place, for I would deeply desire to see him overcome his shame for his past actions, and take up his place at the vanguard of my holy warriors once again." It could be that the 'shame' Saradomin speaks of was Vannaka's defeat at the hands of Duradel, though what made Vannaka leave Saradomin's service and tutor under Duradel in the first place is still unknown. Vannaka was clearly in the army of Saradomin at one point, because Saradomin states he wishes him (Vannaka) to take up his (Vannaka's) place with His (Saradomin's) holy warriors once more.
Vannaka is most well known because of his ability to wield a steel 2h sword, and a dragon sq shield at the same time. This issue was addressed by a player to Saradomin, who replied, "The fearsome Vannaka is one of the strongest warriors to ever grace this world, and as such he has the power to wield what would normally be considered to be a two handed sword single-handedly. This is a strength that most mortals do not posess, and it adds to his fearsome reputation as a great swordsman. It is somewhat of a pity that his glory days are behind him, and his self-imposed exile to tutorial island is in place, for I would deeply desire to see him overcome his shame for his past actions, and take up his place at the vanguard of my holy warriors once again. Perhaps the best we may see of him is his current role as Slayer Master and Combat Instructor, although I suspect his thirst for adventure may bring him back for one last battle, so that he may end his days in glory..." This indicates that Vannaka is a follower of the God of Order. Saradomin also responds, to the player's query of the kind of shield Vannaka wields, "The shield Vannaka wields is the mighty Square Shield of the Dragon, an ancient and powerful artefact possessed only by a few members of this world lucky enough to have found one. He has earnt the right to wield it many times over, and it is something of a trophy for him of past glories."
