Skill outfit add-ons are items won from Treasure Hunter and combined with the headpieces of Experience-boosting sets to grant them additional abilities, whilst maintaining their existing 1% experience boost to their relevant skill. The first batch was released on 5 September 2014, and the second batch was released on 11 June 2015. Players can only win them if they already own the headpiece. Add-ons can also be purchased from Vic's Store when Vic the trader is around. When purchasing from Vic, the list of possible add-ons is not limited to those for which the headgear is already owned.

Each headpiece gains the following effects when modified:

  • Offers three daily teleports to a skill-related location.
  • Generates items, the number related to the number of additional pieces of the outfit owned.
  • Offers a chance to save a skill-related resource or duplicate a created item.
