True skill mastery

Level 120 (or "true skill mastery") is achievable in the skill Dungeoneering and was released 12 April 2010. When a player reaches level 99 in Dungeoneering, they can proceed to 120 to receive a true skill cape. Currently, this is unique to Dungeoneering thus is not possible to reach 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.

104,273,166 experience is needed to reach level 120. This is about 8 times the experience as 'Skill Mastery'. No player has level 120 in Dungeoneering at this time. There are currently no plans to raise the skill barrier for any other skills. There are only floors up to level 69 (floor 35), so there is no floor for true skill masters.
