True skill mastery

True skill mastery is an achievement greater than skill mastery currently obtainable only by reaching level 120 in Dungeoneering. The achievement was released 12 April 2010 with the release of Dungeoneering. When a player reaches level 99 in Dungeoneering, they can continue to proceed to level 120 to receive a true skill cape. Currently, this is unique to Dungeoneering; thus it is not possible to (permanently) exceed level 99 in any other skill. The true mastery skill cape (according to the skill interface) does not look much different from the ordinary level 99 skill cape, and it is unknown if it will have a "true skill cape" emote, or any other additional bonuses.

104,273,167 experience is needed to reach level 120. This is about 8 times the experience as 'Skill Mastery'. as of 8/11/10 no one has achieved level 120 in Dungeoneering and at this time and only 585 players (as of 12 August 2010) have reached level 99. It appears that Jagex currently has no plans to raise the level cap for any other skill .There are only floors up to level 69 (floor 35), so there are no special floors for true skill masters, although reaching level 120 does give a player the ability to bind up to four items..

Trivia

 * It was thought that a glitch where most of the levels on the stats tab flash to level 120 for a quick second however many players now consider it to be an Easter egg by Jagex as the total level is 1337, meaning leet in leet speak.
 * If Daemonheim contained unique floors all the way up to True Skill Mastery, the highest floor would be floor 60, accessible at levels 119 and 120. True skill masters would not have their own floor.


 * After the Dungeoneering update each floor environment has its own waiting room with a circle drawn in it (even the unreleased occult and warped). There is also a similar circle in the middle of the castle, which may have something to do with 120 Dungeoneering.


 * Each specific theme (Frozen, Abandoned, Furnished and the yet to be released Occult) has twelve floors, with the exception of Frozen which is one short. If Warped follows this pattern, 59 floors will be available, reaching level 117. This is one floor short of the above mentioned floor 60.
 * Judging by the in-game guide picture, the level 120 Dungeoneering cape has a gold trim.
 * There was a glitch that when you reach level 115 Dungeoneering in RuneScape, it would say you are level 120 on high scores despite saying level 115 in RuneScape. Jagex removed all accounts with "level 120" from high scores and fixed them individually to reflect the proper levels.
 * If the level cap on all combat skills were raised to 120, the maximum combat level would be 168.
 * Jagex stated that True Skill Mastery of Dungeoneering will reveal more about the Strange Power event.
